| 2 | * | ||
| 3 | * raudio v1.1 - A simple and easy-to-use audio library based on miniaudio | ||
| 4 | * | ||
| 5 | * FEATURES: | ||
| 6 | * - Manage audio device (init/close) | ||
| 7 | * - Manage raw audio context | ||
| 8 | * - Manage mixing channels | ||
| 9 | * - Load and unload audio files | ||
| 10 | * - Format wave data (sample rate, size, channels) | ||
| 11 | * - Play/Stop/Pause/Resume loaded audio | ||
| 12 | * | ||
| 13 | * CONFIGURATION: | ||
| 14 | * #define SUPPORT_MODULE_RAUDIO | ||
| 15 | * raudio module is included in the build | ||
| 16 | * | ||
| 17 | * #define RAUDIO_STANDALONE | ||
| 18 | * Define to use the module as standalone library (independently of raylib). | ||
| 19 | * Required types and functions are defined in the same module. | ||
| 20 | * | ||
| 21 | * #define SUPPORT_FILEFORMAT_WAV | ||
| 22 | * #define SUPPORT_FILEFORMAT_OGG | ||
| 23 | * #define SUPPORT_FILEFORMAT_MP3 | ||
| 24 | * #define SUPPORT_FILEFORMAT_QOA | ||
| 25 | * #define SUPPORT_FILEFORMAT_FLAC | ||
| 26 | * #define SUPPORT_FILEFORMAT_XM | ||
| 27 | * #define SUPPORT_FILEFORMAT_MOD | ||
| 28 | * Selected desired fileformats to be supported for loading. Some of those formats are | ||
| 29 | * supported by default, to remove support, just comment unrequired #define in this module | ||
| 30 | * | ||
| 31 | * DEPENDENCIES: | ||
| 32 | * miniaudio.h - Audio device management lib (https://github.com/mackron/miniaudio) | ||
| 33 | * stb_vorbis.h - Ogg audio files loading (http://www.nothings.org/stb_vorbis/) | ||
| 34 | * dr_wav.h - WAV audio files loading (http://github.com/mackron/dr_libs) | ||
| 35 | * dr_mp3.h - MP3 audio file loading (https://github.com/mackron/dr_libs) | ||
| 36 | * dr_flac.h - FLAC audio file loading (https://github.com/mackron/dr_libs) | ||
| 37 | * jar_xm.h - XM module file loading | ||
| 38 | * jar_mod.h - MOD audio file loading | ||
| 39 | * | ||
| 40 | * CONTRIBUTORS: | ||
| 41 | * David Reid (github: @mackron) (Nov. 2017): | ||
| 42 | * - Complete port to miniaudio library | ||
| 43 | * | ||
| 44 | * Joshua Reisenauer (github: @kd7tck) (2015): | ||
| 45 | * - XM audio module support (jar_xm) | ||
| 46 | * - MOD audio module support (jar_mod) | ||
| 47 | * - Mixing channels support | ||
| 48 | * - Raw audio context support | ||
