miniaudio is written in C with no dependencies except the standard library and should compile clean on all major

compilers without the need to install any additional development packages. All major desktop and mobile platforms

are supported.



Features

========

- Simple build system with no external dependencies.

- Simple and flexible API.

- Low-level API for direct access to raw audio data.

- High-level API for sound management, mixing, effects and optional 3D spatialization.

- Flexible node graph system for advanced mixing and effect processing.

- Resource management for loading sound files.

- Decoding, with built-in support for WAV, FLAC and MP3, in addition to being able to plug in custom decoders.

- Encoding (WAV only).

- Data conversion.

- Resampling, including custom resamplers.

- Channel mapping.

- Basic generation of waveforms and noise.

- Basic effects and filters.



Refer to the [Programming Manual](https://miniaud.io/docs/manual/) for a more complete description of

available features in miniaudio.



Examples

========



This example shows one way to play a sound using the high level API.



```c

#define MINIAUDIO_IMPLEMENTATION

#include "miniaudio.h"



#include 



int main()

{

    ma_result result;

    ma_engine engine;



    result = ma_engine_init(NULL, &engine);

    if (result != MA_SUCCESS) {

        return -1;

    }



    ma_engine_play_sound(&engine, "sound.wav", NULL);



    printf("Press Enter to quit...");

    getchar();



    ma_engine_uninit(&engine);



    return 0;

}

```



This example shows how to decode and play a sound using the low level API.



```c

#define MINIAUDIO_IMPLEMENTATION

#include "miniaudio.h"



#include 



void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount)

{

    ma_decoder* pDecoder = (ma_decoder*)pDevice->pUserData;

    if (pDecoder == NULL) {

        return;

    }



    ma_decoder_read_pcm_frames(pDecoder, pOutput, frameCount, NULL);



    (void)pInput;

}



int main(int argc, char** argv)

{

    ma_result result;

    ma_decoder decoder;

    ma_device_config deviceConfig;

    ma_device device;



    if (argc < 2) {

        printf("No input file.\n");

        return -1;

    }



    result = ma_decoder_init_file(argv[1], NULL, &decoder);

    if (result != MA_SUCCESS) {

        return -2;

    }



    deviceConfig = ma_device_config_init(ma_device_type_playback);

    deviceConfig.playback.format   = decoder.outputFormat;

    deviceConfig.playback.channels = decoder.outputChannels;

    deviceConfig.sampleRate        = decoder.outputSampleRate;

    deviceConfig.dataCallback      = data_callback;

    deviceConfig.pUserData         = &decoder;



    if (ma_device_init(NULL, &deviceConfig, &device) != MA_SUCCESS) {

        printf("Failed to open playback device.\n");

        ma_decoder_uninit(&decoder);

        return -3;

    }



    if (ma_device_start(&device) != MA_SUCCESS) {

        printf("Failed to start playback device.\n");

        ma_device_uninit(&device);

        ma_decoder_uninit(&decoder);

        return -4;

    }



    printf("Press Enter to quit...");

    getchar();



    ma_device_uninit(&device);

    ma_decoder_uninit(&decoder);



    return 0;

}

```

Building

========

Do the following in one source file:

```c

#define MINIAUDIO_IMPLEMENTATION

#include "miniaudio.h"

```

Then just compile. There's no need to install any dependencies. On Windows and macOS there's no need to link

to anything. On Linux just link to `-lpthread`, `-lm` and `-ldl`. On BSD just link to `-lpthread` and `-lm`.

On iOS you need to compile as Objective-C.



If you get errors about undefined references to `__sync_val_compare_and_swap_8`, `__atomic_load_8`, etc. you

need to link with `-latomic`.



If you prefer separate .h and .c files, you can find a split version of miniaudio in the extras/miniaudio_split

folder. From here you can use miniaudio as a traditional .c and .h library - just add miniaudio.c to your source

tree like any other source file and include miniaudio.h like a normal header. If you prefer compiling as a

single translation unit (AKA unity builds), you can just #include the .c file in your main source file:

```c

#include "miniaudio.c"

```

Note that the split version is auto-generated using a tool and is based on the main file in the root directory.

If you want to contribute, please make the change in the main file.



ABI compatibility is not guaranteed between versions so take care if compiling as a DLL/SO. The suggested way

to integrate miniaudio is by adding it directly to your source tree.



Documentation

=============

Online documentation can be found here: https://miniaud.io/docs/



Documentation can also be found at the top of [miniaudio.h](https://raw.githubusercontent.com/mackron/miniaudio/master/miniaudio.h)

which is always the most up-to-date and authoritive source of information on how to use miniaudio. All other

documentation is generated from this in-code documentation.



Supported Platforms

===================

- Windows

- macOS, iOS

- Linux

- FreeBSD / OpenBSD / NetBSD

- Android

- Raspberry Pi

- Emscripten / HTML5



miniaudio should compile clean on other platforms, but it will not include any support for playback or capture

by default. To support that, you would need to implement a custom backend. You can do this without needing to

modify the miniaudio source code. See the [custom_backend](examples/custom_backend.c) example.



Backends

--------

- WASAPI

- DirectSound

- WinMM

- Core Audio (Apple)

- ALSA

- PulseAudio

- JACK

- sndio (OpenBSD)

- audio(4) (NetBSD and OpenBSD)

- OSS (FreeBSD)

- AAudio (Android 8.0+)

- OpenSL|ES (Android only)

- Web Audio (Emscripten)

- Null (Silence)

- Custom
