tinyaudio

tinyaudio provides a cross-platform interface for sending 16-bit stereo PCM data to the device's audio hardware.

tinyaudio does NOT provide any type of mixing (gain, voice, panning, playback) support. I do provide another library (tinymixer) that provides a "normal" audio interface for a game project. The two projects are meant to work together; For sanity I keep tinymixer free from all platform specific code.

Current support exists for:

• Windows (xaudio)
• Chrome NativeClient
• null driver
• Linux (ALSA)
• Linux (pulse)

Integrating with your codebase

The easiest way to integrate tinyaudio into your project is to simply include the appropriate .cpp file inside of /src/ directly in your project.

Alternatively you can compile your platform's driver .cpp into a static library and link it.

For AirMech I literally have the following code in sound/compile/device.cpp:

#if HEAT_COMPILER_MSVC
#	include <tinyaudio_xaudio.cpp>
#elif HEAT_PLATFORM_NACL
#	include <tinyaudio_nacl.cpp>
...
#else
#	include <tinyaudio_null.cpp>
#endif

Including a .cpp file directly may feel dirty, but it's a heck of a lot easier than managing another 3rdparty pre-built library.

How to use tinyaudio in your game

Simply call tinyaudio::init with a callback handler to generate 16bit stereo PCM data. tinyaudio will invoke your callback when data is needed by the hardware. Simply fill the buffer in a timely manner to avoid audio lag.
