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;
|
||||
}
|
||||
```
