Support for signed integers and floats. Audio data fed to/from an RtAudio stream is assumed to ALWAYS be in host byte order. The internal routines will automatically take care of any necessary byte-swapping between the host format and the soundcard. Thus, endian-ness is not a concern in the following format definitions. Note that 24-bit data is expected to be encapsulated in a 32-bit format.

RtAudio stream status (over- or underflow) flags.

Notification of a stream over- or underflow is indicated by a non-zero stream status argument in the RtAudioCallback function. The stream status can be one of the following two options, depending on whether the stream is open for output and/or input:

RtAudio callback function prototype.

All RtAudio clients must create a function of type RtAudioCallback to read and/or write data from/to the audio stream. When the underlying audio system is ready for new input or output data, this function will be invoked.

Parameters:
- - - - - - - +
Parameters
+
outputBuffer For output (or duplex) streams, the client should write nFrames of audio sample frames into this buffer. This argument should be recast to the datatype specified when the stream was opened. For input-only streams, this argument will be NULL.
inputBuffer For input (or duplex) streams, this buffer will hold nFrames of input audio sample frames. This argument should be recast to the datatype specified when the stream was opened. For output-only streams, this argument will be NULL.
nFrames The number of sample frames of input or output data in the buffers. The actual buffer size in bytes is dependent on the data type and number of channels in use.
streamTime The number of seconds that have elapsed since the stream was started.
status If non-zero, this argument indicates a data overflow or underflow condition for the stream. The particular condition can be determined by comparison with the RtAudioStreamStatus flags.
userData A pointer to optional data provided by the client when opening the stream (default = NULL).

To continue normal stream operation, the RtAudioCallback function should return a value of zero. To stop the stream and drain the output buffer, the function should return a value of one. To abort the stream immediately, the client should return a value of two.

The RtAudio API incorporates many of the concepts developed in the PortAudio project by Phil Burk and Ross Bencina. Early development also incorporated ideas from Bill Schottstaedt's sndlib. The CCRMA SoundWire group provided valuable feedback during the API proposal stages.

The early 2.0 version of RtAudio was slowly developed over the course of many months while in residence at the Institut Universitari de L'Audiovisual (IUA) in Barcelona, Spain and the Laboratory of Acoustics and Audio Signal Processing at the Helsinki University of Technology, Finland. Much subsequent development happened while working at the Center for Computer Research in Music and Acoustics (CCRMA) at Stanford University. All recent versions of RtAudio have been completed while working as an assistant / associate professor of Music Technology at McGill University. This work was supported in part by the United States Air Force Office of Scientific Research (grant #F49620-99-1-0293).

API Notes

RtAudio is designed to provide a common API across the various supported operating systems and audio libraries. Despite that, some issues should be mentioned with regard to each.

+

RtAudio is designed to provide a common API across the various supported operating systems and audio libraries. Despite that, some issues should be mentioned with regard to each.

+

+Linux:

RtAudio for Linux was developed under Redhat distributions 7.0 - Fedora. Four different audio APIs are supported on Linux platforms: OSS (versions >= 4.0), ALSA, Jack, and PulseAudio. Note that RtAudio now only supports the newer version 4.0 OSS API. The ALSA API is now part of the Linux kernel and offers significantly better functionality than the OSS API. RtAudio provides support for the 1.0 and higher versions of ALSA. Jack is a low-latency audio server written primarily for the GNU/Linux operating system. It can connect a number of different applications to an audio device, as well as allow them to share audio between themselves. Input/output latency on the order of 15 milliseconds can typically be achieved using any of the Linux APIs by fine-tuning the RtAudio buffer parameters (without kernel modifications). Latencies on the order of 5 milliseconds or less can be achieved using a low-latency kernel patch and increasing FIFO scheduling priority. The pthread library, which is used for callback functionality, is a standard component of all Linux distributions.

The ALSA library includes OSS emulation support. That means that you can run programs compiled for the OSS API even when using the ALSA drivers and library. It should be noted however that OSS emulation under ALSA is not perfect. Specifically, channel number queries seem to consistently produce invalid results. While OSS emulation is successful for the majority of RtAudio tests, it is recommended that the native ALSA implementation of RtAudio be used on systems which have ALSA drivers installed.

The ALSA implementation of RtAudio makes no use of the ALSA "plug" interface. All necessary data format conversions, channel compensation, de-interleaving, and byte-swapping is handled by internal RtAudio routines.

-

-Macintosh OS-X (CoreAudio and Jack):

-

The Apple CoreAudio API is designed to use a separate callback procedure for each of its audio devices. A single RtAudio duplex stream using two different devices is supported, though it cannot be guaranteed to always behave correctly because we cannot synchronize these two callbacks. The numberOfBuffers parameter to the RtAudio::openStream() function has no affect in this implementation.

The numberOfBuffers parameter to the RtAudio::openStream() function has no affect in this implementation.

It is not possible to have multiple instances of RtAudio accessing the same CoreAudio device.

The RtAudio Jack support can be compiled on Macintosh OS-X systems, as well as in Linux.

-Windows (DirectSound):

-

The configure script provides support for the MinGW compiler. DirectSound support is specified with the "--with-ds" flag.

+

+Windows (DirectSound):

+

The configure script provides support for the MinGW compiler. DirectSound support is specified with the "&ndash;with-ds" flag.

In order to compile RtAudio under Windows for the DirectSound API, you must have the header and source files for DirectSound version 5.0 or higher. As far as I know, there is no DirectSoundCapture support for Windows NT. Audio output latency with DirectSound can be reasonably good, especially since RtAudio version 3.0.2. Input audio latency still tends to be bad but better since version 3.0.2. RtAudio was originally developed with Visual C++ version 6.0 but has been tested with .NET.

The DirectSound version of RtAudio can be compiled with or without the UNICODE preprocessor definition.

-

-Windows (ASIO):

-

ASIO support using MinGW and the configure script is specified with the "--with-asio" flag.

-

The Steinberg ASIO audio API allows only a single device driver to be loaded and accessed at a time. ASIO device drivers must be supplied by audio hardware manufacturers, though ASIO emulation is possible on top of systems with DirectSound drivers. The numberOfBuffers parameter to the RtAudio::openStream() function has no affect in this implementation.

ASIO device drivers must be supplied by audio hardware manufacturers, though ASIO emulation is possible on top of systems with DirectSound drivers. The numberOfBuffers parameter to the RtAudio::openStream() function has no affect in this implementation.

A number of ASIO source and header files are required for use with RtAudio. Specifically, an RtAudio project must include the following files: asio.h,cpp; asiodrivers.h,cpp; asiolist.h,cpp; asiodrvr.h; asiosys.h; ginclude.h; iasiodrv.h; iasiothiscallresolver.h,cpp. The Visual C++ projects found in /tests/Windows/ compile both ASIO and DirectSound support.

The Steinberg provided asiolist class does not compile when the preprocessor definition UNICODE is defined. Note that this could be an issue when using RtAudio with Qt, though Qt programs appear to compile without the UNICODE definition (try DEFINES -= UNICODE in your .pro file). RtAudio with ASIO support has been tested using the MinGW compiler under Windows XP, as well as in the Visual Studio environment.

Return an RtAudio::DeviceInfo structure for a specified device number.

Any device integer between 0 and getDeviceCount() - 1 is valid. If an invalid argument is provided, an RtError (type = INVALID_USE) will be thrown. If a device is busy or otherwise unavailable, the structure member "probed" will have a value of "false" and all other members are undefined. If the specified device is the current default input or output device, the corresponding "isDefault" member will have a value of "true".

+

A public function for opening a stream with the specified parameters.

An RtError (type = SYSTEM_ERROR) is thrown if a stream cannot be opened with the specified parameters or an error occurs during processing. An RtError (type = INVALID_USE) is thrown if any invalid device ID or channel number parameters are specified.

-
Parameters:
- - - - - - - - - +
Parameters
+
outputParameters Specifies output stream parameters to use when opening a stream, including a device ID, number of channels, and starting channel number. For input-only streams, this argument should be NULL. The device ID is an index value between 0 and getDeviceCount() - 1.
inputParameters Specifies input stream parameters to use when opening a stream, including a device ID, number of channels, and starting channel number. For output-only streams, this argument should be NULL. The device ID is an index value between 0 and getDeviceCount() - 1.
format An RtAudioFormat specifying the desired sample data format.
sampleRate The desired sample rate (sample frames per second).
*bufferFrames A pointer to a value indicating the desired internal buffer size in sample frames. The actual value used by the device is returned via the same pointer. A value of zero can be specified, in which case the lowest allowable value is determined.
callback A client-defined function that will be invoked when input data is available and/or output data is needed.
userData An optional pointer to data that can be accessed from within the callback function.
options An optional pointer to a structure containing various global stream options, including a list of OR'ed RtAudioStreamFlags and a suggested number of stream buffers that can be used to control stream latency. More buffers typically result in more robust performance, though at a cost of greater latency. If a value of zero is specified, a system-specific median value is chosen. If the RTAUDIO_MINIMIZE_LATENCY flag bit is set, the lowest allowable value is used. The actual value used is returned via the structure argument. The parameter is API dependent.

A function that closes a stream and frees any associated stream memory.

If a stream is not open, this function issues a warning and returns (no exception is thrown).

- +
+ + + + + +
- - - - + + +
void RtAudio::startStream (void  )  [inline]void )
- -
+
+inline
+

A function that starts a stream.

An RtError (type = SYSTEM_ERROR) is thrown if an error occurs during processing. An RtError (type = INVALID_USE) is thrown if a stream is not open. A warning is issued if the stream is already running.

- +
+ + + + + +
- - - - + + +
void RtAudio::stopStream (void  )  [inline]void )
- -
+
+inline
+

Stop a stream, allowing any samples remaining in the output queue to be played.

An RtError (type = SYSTEM_ERROR) is thrown if an error occurs during processing. An RtError (type = INVALID_USE) is thrown if a stream is not open. A warning is issued if the stream is already stopped.

- +
+ + + + + +
- - - - + + +
void RtAudio::abortStream (void  )  [inline]void )
- -
+
+inline
+

Stop a stream, discarding any samples remaining in the input/output queue.

+ + + + + +
- - - - + + +
long RtAudio::getStreamLatency (void  )  [inline]void )
- -
+
+inline
+

Returns the internal stream latency in sample frames.

The stream latency refers to delay in audio input and/or output caused by internal buffering by the audio system and/or hardware. For duplex streams, the returned value will represent the sum of the input and output latencies. If a stream is not open, an RtError (type = INVALID_USE) will be thrown. If the API does not report latency, the return value will be zero.

- +
+ + + + + +
- - - - + + +
unsigned int RtAudio::getStreamSampleRate (void  )  [inline]void )
- -
+
+inline
+

Returns actual sample rate in use by the stream.

On some systems, the sample rate used may be slightly different than that specified in the stream parameters. If a stream is not open, an RtError (type = INVALID_USE) will be thrown.

If you are having problems getting RtAudio to run on your system, make sure to pass a value of true to the RtAudio::showWarnings() function (this is the default setting). A variety of warning messages will be displayed which may help in determining the problem. Also, try using the programs included in the tests directory. The program audioprobe displays the queried capabilities of all hardware devices found for all APIs compiled. When using the ALSA and JACK APIs, further information can be displayed by defining the preprocessor definition __RTAUDIO_DEBUG__.

-  // a simple buffer copy operation here.
-  if ( status ) std::cout << "Stream over/underflow detected." << std::endl;

In this example, audio recorded by the stream input will be played out during the next round of audio processing.

Note that a duplex stream can make use of two different devices (except when using the Linux Jack and Windows ASIO APIs). However, this may cause timing problems due to possible device clock variations, unless a common external "sync" is provided.

Error Handling

Error Handling

RtAudio makes restrained use of C++ exceptions. That is, exceptions are thrown only when system errors occur that prevent further class operation or when the user makes invalid function calls. In other cases, a warning message may be displayed and an appropriate value is returned. For example, if a system error occurs when processing the RtAudio::getDeviceCount() function, the return value is zero. In such a case, the user cannot expect to make use of most other RtAudio functions because no devices are available (and thus a stream cannot be opened). A client can call the function RtAudio::showWarnings() with a boolean argument to enable or disable the printing of warning messages to stderr. By default, warning messages are displayed. There is a protected RtAudio method, error(), that can be modified to globally control how these messages are handled and reported.

RtAudio incorporates the concept of audio streams, which represent audio output (playback) and/or input (recording). Available audio devices and their capabilities can be enumerated and then specified when opening a stream. Where applicable, multiple API support can be compiled and a particular API specified when creating an RtAudio instance. See the API Notes section for information specific to each of the supported audio APIs.

Using Simultaneous Multiple APIs
+
- - -

Using Simultaneous Multiple APIs

Because support for each audio API is encapsulated in a specific RtApi subclass, it is possible to compile and instantiate multiple API-specific subclasses on a given operating system. For example, one can compile both the RtApiDs and RtApiAsio classes on Windows operating systems by providing the appropriate preprocessor definitions, include files, and libraries for each. In a run-time situation, one might first attempt to determine whether any ASIO device drivers exist. This can be done by specifying the api argument RtAudio::WINDOWS_ASIO when attempting to create an instance of RtAudio. If no available devices are found, then an instance of RtAudio with the api argument RtAudio::WINDOWS_DS can be created. Alternately, if no api argument is specified, RtAudio will first look for an ASIO instance and then a DirectSound instance (on Linux systems, the default API search order is Jack, Alsa, and finally OSS). In theory, it should also be possible to have separate instances of RtAudio open at the same time with different underlying audio API support, though this has not been tested. It is difficult to know how well different audio APIs can simultaneously coexist on a given operating system. In particular, it is unlikely that the same device could be simultaneously controlled with two different audio APIs.

The static function RtAudio::getCompiledApi() is provided to determine the available compiled API support. The function RtAudio::getCurrentApi() indicates the API selected for a given RtAudio instance.

We open the stream in exactly the same way as the previous example (except with a data format change) and specify the address of our callback function "saw()". The callback function will automatically be invoked when the underlying audio system needs data for output. Note that the callback function is called only when the stream is "running" (between calls to the RtAudio::startStream() and RtAudio::stopStream() functions). We can also pass a pointer value to the RtAudio::openStream() function that is made available in the callback function. In this way, it is possible to gain access to arbitrary data created in our main() function from within the globally defined callback function.

In this way, it is possible to gain access to arbitrary data created in our main() function from within the globally defined callback function.

In this example, we stop the stream with an explicit call to RtAudio::stopStream(). It is also possible to stop a stream by returning a non-zero value from the callback function. A return value of 1 will cause the stream to finish draining its internal buffers and then halt (equivalent to calling the RtAudio::stopStream() function). A return value of 2 will cause the stream to stop immediately (equivalent to calling the RtAudio::abortStream() function).

Probing Device Capabilities

Probing Device Capabilities

A programmer may wish to query the available audio device capabilities before deciding which to use. The following example outlines how this can be done.

-
// audioprobe.cpp
-
-#include <iostream>
-#include "RtAudio.h"
-
-int main()
-{
-  RtAudio audio;
-
-  // Determine the number of devices available
-  unsigned int devices = audio.getDeviceCount();
-
-  // Scan through devices for various capabilities
-  RtAudio::DeviceInfo info;
-  for ( unsigned int i=0; i<=devices; i++ ) {
-
-    info = audio.getDeviceInfo( i );
-
-    if ( info.probed == true ) {
-      // Print, for example, the maximum number of output channels for each device
-      std::cout << "device = " << i;
-      std::cout << ": maximum output channels = " << info.outputChannels << "\n";
-    }
-  }
-
-  return 0;
-}
-

The RtAudio::DeviceInfo structure is defined in RtAudio.h and provides a variety of information useful in assessing the capabilities of a device:

-
  typedef struct RtAudio::DeviceInfo {
-    bool probed;                           // true if the device capabilities were successfully probed.
-    std::string name;                      // Character string device identifier.
-    unsigned int outputChannels;           // Maximum output channels supported by device.
-    unsigned int inputChannels;            // Maximum input channels supported by device.

-    std::vector<unsigned int> sampleRates; // Supported sample rates.
-    RtAudioFormat nativeFormats;           // Bit mask of supported data formats.
-  };
-

The following data formats are defined and fully supported by RtAudio:

-
  typedef unsigned long RtAudioFormat;
-  static const RtAudioFormat  RTAUDIO_SINT8;   // Signed 8-bit integer
-  static const RtAudioFormat  RTAUDIO_SINT16;  // Signed 16-bit integer
-  static const RtAudioFormat  RTAUDIO_SINT24;  // Signed 24-bit integer (lower 3 bytes of 32-bit signed integer.)
-  static const RtAudioFormat  RTAUDIO_SINT32;  // Signed 32-bit integer
-  static const RtAudioFormat  RTAUDIO_FLOAT32; // 32-bit float normalized between +/- 1.0
-  static const RtAudioFormat  RTAUDIO_FLOAT64; // 64-bit double normalized between +/- 1.0
-

The nativeFormats member of the RtAudio::DeviceInfo structure is a bit mask of the above formats which are natively supported by the device. However, RtAudio will automatically provide format conversion if a particular format is not natively supported. When the probed member of the RtAudio::DeviceInfo structure is false, the remaining structure members are undefined and the device is probably unusable.

+

A programmer may wish to query the available audio device capabilities before deciding which to use. The following example outlines how this can be done.

+
// audioprobe.cpp
+
+
#include <iostream>
+
#include "RtAudio.h"
+
+
int main()
+
{
+
RtAudio audio;
+
+
// Determine the number of devices available
+
unsigned int devices = audio.getDeviceCount();
+
+
// Scan through devices for various capabilities
+
RtAudio::DeviceInfo info;
+
for ( unsigned int i=0; i<=devices; i++ ) {
+
+
info = audio.getDeviceInfo( i );
+
+
if ( info.probed == true ) {
+
// Print, for example, the maximum number of output channels for each device
+
std::cout << "device = " << i;
+
std::cout << ": maximum output channels = " << info.outputChannels << "\n";
+
}
+
}
+
+
return 0;
+
}
+

The RtAudio::DeviceInfo structure is defined in RtAudio.h and provides a variety of information useful in assessing the capabilities of a device:

+
typedef struct RtAudio::DeviceInfo {
+
bool probed; // true if the device capabilities were successfully probed.
+
std::string name; // Character string device identifier.
+
unsigned int outputChannels; // Maximum output channels supported by device.
+
unsigned int inputChannels; // Maximum input channels supported by device.
+
unsigned int duplexChannels; // Maximum simultaneous input/output channels supported by device.
+
bool isDefaultOutput; // true if this is the default output device.
+
bool isDefaultInput; // true if this is the default input device.
+
std::vector<unsigned int> sampleRates; // Supported sample rates.
+
RtAudioFormat nativeFormats; // Bit mask of supported data formats.
+
};
+

The following data formats are defined and fully supported by RtAudio:

+
typedef unsigned long RtAudioFormat;
+
static const RtAudioFormat RTAUDIO_SINT8; // Signed 8-bit integer
+
static const RtAudioFormat RTAUDIO_SINT16; // Signed 16-bit integer
+
static const RtAudioFormat RTAUDIO_SINT24; // Signed 24-bit integer (lower 3 bytes of 32-bit signed integer.)
+
static const RtAudioFormat RTAUDIO_SINT32; // Signed 32-bit integer
+
static const RtAudioFormat RTAUDIO_FLOAT32; // 32-bit float normalized between +/- 1.0
+
static const RtAudioFormat RTAUDIO_FLOAT64; // 64-bit double normalized between +/- 1.0
+

The nativeFormats member of the RtAudio::DeviceInfo structure is a bit mask of the above formats which are natively supported by the device. However, RtAudio will automatically provide format conversion if a particular format is not natively supported. When the probed member of the RtAudio::DeviceInfo structure is false, the remaining structure members are undefined and the device is probably unusable.

Some audio devices may require a minimum channel value greater than one. RtAudio will provide automatic channel number compensation when the number of channels set by the user is less than that required by the device. Channel compensation is NOT possible when the number of channels set by the user is greater than that supported by the device.

It should be noted that the capabilities reported by a device driver or underlying audio API are not always accurate and/or may be dependent on a combination of device settings. For this reason, RtAudio does not rely on the queried values when attempting to open a stream.

Using RtAudio for audio input is almost identical to the way it is used for playback. Here's the blocking playback example rewritten for recording:

-
-  // Do something with the data in the "inputBuffer" buffer.
-
-  return 0;
-}
-
-int main()
-{
-  RtAudio adc;
-  if ( adc.getDeviceCount() < 1 ) {
-    std::cout << "\nNo audio devices found!\n";
-    exit( 0 );
-  }
-
-  RtAudio::StreamParameters parameters;
-  parameters.deviceId = adc.getDefaultInputDevice();
-  parameters.nChannels = 2;
-  parameters.firstChannel = 0;
-  unsigned int sampleRate = 44100;
-  unsigned int bufferFrames = 256; // 256 sample frames
-
-  try {
-    adc.openStream( NULL, &parameters, RTAUDIO_SINT16,
-                    sampleRate, &bufferFrames, &record );
-    adc.startStream();
-  }
-  catch ( RtError& e ) {
-    e.printMessage();
-    exit( 0 );
-  }
-  
-  char input;
-  std::cout << "\nRecording ... press <enter> to quit.\n";
-  std::cin.get( input );

-    e.printMessage();
-  }

In this example, we pass the address of the stream parameter structure as the second argument of the RtAudio::openStream() function and pass a NULL value for the output stream parameters. In this example, the record() callback function performs no specific operations.

The RtAudio::openStream() function attempts to open a stream with a specified set of parameter values. In the above example, we attempt to open a two channel playback stream using the default output device, 32-bit floating point data, a sample rate of 44100 Hz, and a frame rate of 256 sample frames per output buffer. If the user specifies an invalid parameter value (such as a device id greater than or equal to the number of enumerated devices), an RtError is thrown of type = INVALID_USE. If a system error occurs or the device does not support the specified parameter values, an RtError of type = SYSTEM_ERROR is thrown. In either case, a descriptive error message is bundled with the exception and can be queried with the RtError::getMessage() or RtError::what() functions.

The RtAudio::openStream() function attempts to open a stream with a specified set of parameter values. In the above example, we attempt to open a two channel playback stream using the default output device, 32-bit floating point data, a sample rate of 44100 Hz, and a frame rate of 256 sample frames per output buffer. If the user specifies an invalid parameter value (such as a device id greater than or equal to the number of enumerated devices), an RtError is thrown of type = INVALID_USE. If a system error occurs or the device does not support the specified parameter values, an RtError of type = SYSTEM_ERROR is thrown. In either case, a descriptive error message is bundled with the exception and can be queried with the RtError::getMessage() or RtError::what() functions.

RtAudio provides four signed integer and two floating point data formats which can be specified using the RtAudioFormat parameter values mentioned earlier. If the opened device does not natively support the given format, RtAudio will automatically perform the necessary data format conversion.

The bufferFrames parameter specifies the desired number of sample frames that will be written to and/or read from a device per write/read operation. This parameter can be used to control stream latency though there is no guarantee that the passed value will be that used by a device. In general, a lower bufferFrames value will produce less latency but perhaps less robust performance. A value of zero can be specified, in which case the smallest allowable value will be used. The bufferFrames parameter is passed as a pointer and the actual value used by the stream is set during the device setup procedure. bufferFrames values should be a power of two. Optimal and allowable buffer values tend to vary between systems and devices. Stream latency can also be controlled via the optional RtAudio::StreamOptions member numberOfBuffers (not used in the example above), though this tends to be more system dependent. In particular, the numberOfBuffers parameter is ignored when using the OS-X Core Audio, Jack, and the Windows ASIO APIs.

As noted earlier, the device capabilities reported by a driver or underlying audio API are not always accurate and/or may be dependent on a combination of device settings. Because of this, RtAudio does not attempt to query a device's capabilities or use previously reported values when opening a device. Instead, RtAudio simply attempts to set the given parameters on a specified device and then checks whether the setup is successful or not.

The RtAudioCallback parameter above is a pointer to a user-defined function that will be called whenever the audio system is ready for new output data or has new input data to be read. Further details on the use of a callback function are provided in the next section.

Several stream options are available to fine-tune the behavior of an audio stream. In the example above, we specify that data will be written by the user in a non-interleaved format via the RtAudio::StreamOptions member flags. That is, all bufferFrames of the first channel should be written consecutively, followed by all bufferFrames of the second channel. By default (when no option is specified), RtAudio expects data to be written in an interleaved format.

By default, RtAudio streams pass and receive audio data from the client in an interleaved format. By passing the RTAUDIO_NONINTERLEAVED flag to the openStream() function, audio data will instead be presented in non-interleaved buffers. In this case, each buffer argument in the RtAudioCallback function will point to a single array of data, with nFrames samples for each channel concatenated back-to-back. For example, the first sample of data for the second channel would be located at index nFrames (assuming the buffer pointer was recast to the correct data type for the stream).

-

Certain audio APIs offer a number of parameters that influence the I/O latency of a stream. By default, RtAudio will attempt to set these parameters internally for robust (glitch-free) performance (though some APIs, like Windows Direct Sound, make this difficult). By passing the RTAUDIO_MINIMIZE_LATENCY flag to the openStream() function, internal stream settings will be influenced in an attempt to minimize stream latency, though possibly at the expense of stream performance.

If the RTAUDIO_HOG_DEVICE flag is set, RtAudio will attempt to open the input and/or output stream device(s) for exclusive use. Note that this is not possible with all supported audio APIs.

If the RTAUDIO_SCHEDULE_REALTIME flag is set, RtAudio will attempt to select realtime scheduling (round-robin) for the callback thread. The priority parameter will only be used if the RTAUDIO_SCHEDULE_REALTIME flag is set. It defines the thread's realtime priority.

If the RTAUDIO_ALSA_USE_DEFAULT flag is set, RtAudio will attempt to open the "default" PCM device when using the ALSA API. Note that this will override any specified input or output device id.

The numberOfBuffers parameter can be used to control stream latency in the Windows DirectSound, Linux OSS, and Linux Alsa APIs only. A value of two is usually the smallest allowed. Larger numbers can potentially result in more robust stream performance, though likely at the cost of stream latency. The value set by the user is replaced during execution of the RtAudio::openStream() function by the value actually used by the system.
