<h1>Fixed Size Callback</h1><p>
|
||||
Shows one way to implement a data callback that is called with a fixed frame count.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
miniaudio does not have built-in support for firing the data callback with fixed sized buffers. In order to support
|
||||
this you need to implement a layer that sits on top of the normal data callback. This example demonstrates one way of
|
||||
doing this.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
This example uses a ring buffer to act as the intermediary buffer between the low-level device callback and the fixed
|
||||
sized callback. You do not need to use a ring buffer here, but it's a good opportunity to demonstrate how to use
|
||||
miniaudio's ring buffer API. The ring buffer in this example is in global scope for simplicity, but you can pass it
|
||||
around as user data for the device (device.pUserData).
|
||||
</p>
|
||||
<p>
|
||||
|
||||
This example only works for output devices, but can be implemented for input devices by simply swapping the direction
|
||||
of data movement.</p>

<h1>Simple Capture</h1><p>
|
||||
Demonstrates how to capture data from a microphone using the low-level API.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
This example simply captures data from your default microphone until you press Enter. The output is saved to the file
|
||||
specified on the command line.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
Capturing works in a very similar way to playback. The only difference is the direction of data movement. Instead of
|
||||
the application sending data to the device, the device will send data to the application. This example just writes the
|
||||
data received by the microphone straight to a WAV file.</p>

<h1>Simple Duplex</h1><p>
|
||||
Demonstrates duplex mode which is where data is captured from a microphone and then output to a device.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
This example captures audio from the default microphone and then outputs it straight to the default playback device
|
||||
without any kind of modification. If you wanted to, you could also apply filters and effects to the input stream
|
||||
before outputting to the playback device.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
Note that the microphone and playback device must run in lockstep. Any kind of timing deviation will result in audible
|
||||
glitching which the backend may not be able to recover from. For this reason, miniaudio forces you to use the same
|
||||
sample rate for both capture and playback. If internally the native sample rates differ, miniaudio will perform the
|
||||
sample rate conversion for you automatically.</p>

<h1>Simple Enumeration</h1><p>
|
||||
Demonstrates how to enumerate over devices.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
Device enumaration requires a <span style="font-family:monospace;">ma_context</span> object which is initialized with <span style="font-family:monospace;">ma_context_init()</span>. Conceptually, the
|
||||
context sits above a device. You can have many devices to one context.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
If you use device enumeration, you should explicitly specify the same context you used for enumeration in the call to
|
||||
<span style="font-family:monospace;">ma_device_init()</span> when you initialize your devices.</p>

<h1>Simple Loopback</h1><p>
|
||||
Demonstrates how to implement loopback recording.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
This example simply captures data from your default playback device until you press Enter. The output is saved to the
|
||||
file specified on the command line.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
Loopback mode is when you record audio that is played from a given speaker. It is only supported on WASAPI, but can be
|
||||
used indirectly with PulseAudio by choosing the appropriate loopback device after enumeration.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
To use loopback mode you just need to set the device type to ma_device_type_loopback and set the capture device config
|
||||
properties. The output buffer in the callback will be null whereas the input buffer will be valid.</p>

<h1>Simple Looping</h1><p>
|
||||
Shows one way to handle looping of a sound.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
This example uses a decoder as the data source. Decoders can be used with the <span style="font-family:monospace;">ma_data_source</span> API which, conveniently,
|
||||
supports looping via the <span style="font-family:monospace;">ma_data_source_read_pcm_frames()</span> API. To use it, all you need to do is pass a pointer to the
|
||||
decoder straight into <span style="font-family:monospace;">ma_data_source_read_pcm_frames()</span> and it will just work.</p>

<h1>Simple Mixing</h1><p>
|
||||
Demonstrates one way to load multiple files and play them all back at the same time.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
When mixing multiple sounds together, you should not create multiple devices. Instead you should create only a single
|
||||
device and then mix your sounds together which you can do by simply summing their samples together. The simplest way to
|
||||
do this is to use floating point samples and use miniaudio's built-in clipper to handling clipping for you. (Clipping
|
||||
is when sample are clampled to their minimum and maximum range, which for floating point is -1..1.)

<h1>Simple Playback</h1><p>
|
||||
Demonstrates how to load a sound file and play it back using the low-level API.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
The low-level API uses a callback to deliver audio between the application and miniaudio for playback or recording. When
|
||||
in playback mode, as in this example, the application sends raw audio data to miniaudio which is then played back through
|
||||
the default playback device as defined by the operating system.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
This example uses the <span style="font-family:monospace;">ma_decoder</span> API to load a sound and play it back. The decoder is entirely decoupled from the
|
||||
device and can be used independently of it. This example only plays back a single sound file, but it's possible to play
|
||||
back multiple files by simple loading multiple decoders and mixing them (do not create multiple devices to do this). See
|
||||
the simple_mixing example for how best to do this.</p>

<h1>Simple Playback Sine</h1><p>
|
||||
Demonstrates playback of a sine wave.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
Since all this example is doing is playing back a sine wave, we can disable decoding (and encoding) which will slightly
|
||||
reduce the size of the executable. This is done with the <span style="font-family:monospace;">MA_NO_DECODING</span> and <span style="font-family:monospace;">MA_NO_ENCODING</span> options.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
The generation of sine wave is achieved via the <span style="font-family:monospace;">ma_waveform</span> API. A waveform is a data source which means it can be
|
||||
seamlessly plugged into the <span style="font-family:monospace;">ma_data_source_*()</span> family of APIs as well.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
A waveform is initialized using the standard config/init pattern used throughout all of miniaudio. Frames are read via
|
||||
the <span style="font-family:monospace;">ma_waveform_read_pcm_frames()</span> API.
|
||||
</p>
|
||||
<p>
|
||||
|
||||
This example works with Emscripten.</p>
