-RtAudio is a set of C++ classes that provide a common API (Application Programming Interface) for realtime audio input/output across Linux, Macintosh OS-X and Windows (DirectSound and ASIO) operating systems. RtAudio significantly simplifies the process of interacting with computer audio hardware. It was designed with the following objectives:

RtAudio significantly simplifies the process of interacting with computer audio hardware. It was designed with the following objectives:
<UL>
<LI>object-oriented C++ design</LI>
<LI>simple, common API across all supported platforms</LI>
- <LI>only one source and two header files for easy inclusion in programming projects</LI>
+ <LI>only one source and one header file for easy inclusion in programming projects</LI>
<LI>allow simultaneous multi-api support</LI>
<LI>support dynamic connection of devices</LI>
<LI>provide extensive audio device parameter control</LI>
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 \ref apinotes section for information specific to each of the supported audio APIs.
-\section whatsnew What's New (Version 4.0)
+\section whatsnew Latest Updates (Version 4.1.0)
-RtAudio V4 represents a significant rewrite of the code and includes a number of API and functionality changes from previous versions. A partial list of the changes includes:
-- new support for non-interleaved user data
-- additional input/output parameter specifications, including channel offset
-- new support for dynamic connection of devices
-- new support for stream time
-- revised callback arguments, including separate input and output buffer arguments
-- revised C++ exception handling
-- updated support for OSS version 4.0
-- discontinued support of blocking functionality
-- discontinued support of SGI
+A minor API change was made. The RtError class was renamed RtAudioError and embedded directly in RtAudio.h. Thus, all references to RtError should be renamed to RtAudioError and the RtError.h file should be deleted.
-Devices are now re-enumerated every time the RtAudio::getDeviceCount(), RtAudio::getDeviceInfo(), and RtAudio::openStream() functions are called. This allows for the proper identification of hot-pluggable (USB, Firewire, ...) devices that are connected after an RtAudio instance is created.
+Changes in the previous 4.0.12 release included:
+
+- new functionality to allow error reporting via a client-supplied function (thanks to Pavel Mogilevskiy)
+- new function to return the version number
+- updated RtAudio.cpp and ASIO files for UNICODE support (thanks to Renaud Schoonbroodt)
+- updates to PulseAudio API support (thanks to Peter Meerwald and Tristan Matthews)
+- updates for pkg-config support in configure script
+- 24-bit format changed to true 24-bit format, not sub-bytes of 32-bits (thanks to Marc Britton)
+- bug fixes to make sure stream status is closed if error during probeDeviceOpen
+- updates / fixes to SCHED_RR code in ALSA (thanks to Marc Lindahl)
+- various changes to avoid global variables (thanks to Martin Koegler)
