|
*
|
||
|
* raudio v1.0 - A simple and easy-to-use audio library based on miniaudio
|
||
|
*
|
||
|
* FEATURES:
|
||
|
* - Manage audio device (init/close)
|
||
|
* - Manage raw audio context
|
||
|
* - Manage mixing channels
|
||
|
* - Load and unload audio files
|
||
|
* - Format wave data (sample rate, size, channels)
|
||
|
* - Play/Stop/Pause/Resume loaded audio
|
||
|
*
|
||
|
* CONFIGURATION:
|
||
|
*
|
||
|
* #define SUPPORT_MODULE_RAUDIO
|
||
|
* raudio module is included in the build
|
||
|
*
|
||
|
* #define RAUDIO_STANDALONE
|
||
|
* Define to use the module as standalone library (independently of raylib).
|
||
|
* Required types and functions are defined in the same module.
|
||
|
*
|
||
|
* #define SUPPORT_FILEFORMAT_WAV
|
||
|
* #define SUPPORT_FILEFORMAT_OGG
|
||
|
* #define SUPPORT_FILEFORMAT_XM
|
||
|
* #define SUPPORT_FILEFORMAT_MOD
|
||
|
* #define SUPPORT_FILEFORMAT_FLAC
|
||
|
* #define SUPPORT_FILEFORMAT_MP3
|
||
|
* Selected desired fileformats to be supported for loading. Some of those formats are
|
||
|
* supported by default, to remove support, just comment unrequired #define in this module
|
||
|
*
|
||
|
* DEPENDENCIES:
|
||
|
* miniaudio.h - Audio device management lib (https://github.com/mackron/miniaudio)
|
||
|
* stb_vorbis.h - Ogg audio files loading (http://www.nothings.org/stb_vorbis/)
|
||
|
* dr_wav.h - WAV audio files loading (http://github.com/mackron/dr_libs)
|
||
|
* dr_mp3.h - MP3 audio file loading (https://github.com/mackron/dr_libs)
|
||
|
* dr_flac.h - FLAC audio file loading (https://github.com/mackron/dr_libs)
|
||
|
* jar_xm.h - XM module file loading
|
||
|
* jar_mod.h - MOD audio file loading
