mini_al - Mini Audio Library
============================
mini_al is a simple library for playing and recording audio. It's focused on simplicity and has
a very small number of APIs. This is not a full-featured audio library, nor will it ever be. It
is intended to be used as a quick and easy way to connect to an audio device and deliver and
capture audio data from speakers and microphones.
C/C++, single file, public domain.
Features
========
- A very simple API.
- Both synchronous and asynchronous APIs.
Examples
========
Asynchonous API
---------------
In asynchronous mode, mini_al will request and deliver audio data through callbacks.
```
mal_uint32 on_send_audio_data(mal_device* pDevice, mal_uint32 sampleCount, void* pSamples)
{
return drwav_read_f32((drwav*)pDevice->pUserData, sampleCount, pSamples);
}
int main()
{
mal_uint32 channels = 2;
mal_uint32 sampleRate = 44100;
mal_uint32 fragmentSizeInFrames = 512;
mal_uint32 fragmentCount = 2;
mal_device playbackDevice;
if (mal_device_init(&playbackDevice, mal_device_type_playback, NULL, mal_format_f32, channels, sampleRate, fragmentSizeInFrames, fragmentCount) != MAL_SUCCESS) {
return -1;
}
mal_device_set_send_callback(&playbackDevice, on_send_audio_data);
mal_device_start(&playbackDevice);
printf("Press Enter to quit...\n");
getchar();
mal_device_uninit(&playbackDevice);
return 0;
}
```
Synchronous API
---------------
In synchronous mode, the application submits audio data to the device using APIs which block until
the device is ready to receive it.
```
int main()
{
mal_uint32 channels = 2;
mal_uint32 sampleRate = 44100;
mal_uint32 fragmentSizeInFrames = 512;
mal_uint32 fragmentCount = 2;
mal_device playbackDevice;
if (mal_device_init_synchronous(&playbackDevice, mal_device_type_playback, NULL, mal_format_f32, channels, sampleRate, fragmentSizeInFrames, fragmentCount) != MAL_SUCCESS) {
return -1;
}
mal_device_start(&playbackDevice);
for (;;) {
float pSamples[512];
mal_uint32 samplesToWrite = drwav_read_f32(&wav, fragmentSizeInFrames * fragmentCount, pSamples);
if (samplesToWrite == 0) {
break;
}
mal_uint32 samplesWritten = mal_device_write(&playbackDevice, samplesToWrite, pSamples);
if (samplesWritte != samplesToWrite) {
break;
}
}
mal_device_uninit(&playbackDevice);
return 0;
}
