<p><a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> stream option flags. </p>
|
||||
<p>The following flags can be OR'ed together to allow a client to make changes to the default stream behavior:</p>
|
||||
<ul>
|
||||
<li><em>RTAUDIO_NONINTERLEAVED:</em> Use non-interleaved buffers (default = interleaved).</li>
|
||||
<li><em>RTAUDIO_MINIMIZE_LATENCY:</em> Attempt to set stream parameters for lowest possible latency.</li>
|
||||
<li><em>RTAUDIO_HOG_DEVICE:</em> Attempt grab device for exclusive use.</li>
|
||||
<li><em>RTAUDIO_ALSA_USE_DEFAULT:</em> Use the "default" PCM device (ALSA only).</li>
|
||||
</ul>
|
||||
<p>By default, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> streams pass and receive audio data from the client in an interleaved format. By passing the RTAUDIO_NONINTERLEAVED flag to the openStream() function, audio data will instead be presented in non-interleaved buffers. In this case, each buffer argument in the RtAudioCallback function will point to a single array of data, with <code>nFrames</code> samples for each channel concatenated back-to-back. For example, the first sample of data for the second channel would be located at index <code>nFrames</code> (assuming the <code>buffer</code> pointer was recast to the correct data type for the stream).</p>
|
||||
<p>Certain audio APIs offer a number of parameters that influence the I/O latency of a stream. By default, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> will attempt to set these parameters internally for robust (glitch-free) performance (though some APIs, like Windows Direct Sound, make this difficult). By passing the RTAUDIO_MINIMIZE_LATENCY flag to the openStream() function, internal stream settings will be influenced in an attempt to minimize stream latency, though possibly at the expense of stream performance.</p>
|
||||
<p>If the RTAUDIO_HOG_DEVICE flag is set, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> will attempt to open the input and/or output stream device(s) for exclusive use. Note that this is not possible with all supported audio APIs.</p>
|
||||
<p>If the RTAUDIO_SCHEDULE_REALTIME flag is set, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> will attempt to select realtime scheduling (round-robin) for the callback thread.</p>
|
||||
<p>If the RTAUDIO_ALSA_USE_DEFAULT flag is set, <a class="el" href="classRtAudio.html" title="Realtime audio i/o C++ classes.">RtAudio</a> will attempt to open the "default" PCM device when using the ALSA API. Note that this will override any specified input or output device id. </p>

<p>Notification of a stream over- or underflow is indicated by a non-zero stream <code>status</code> argument in the RtAudioCallback function. The stream status can be one of the following two options, depending on whether the stream is open for output and/or input:</p>
|

<ul>
|

<li><em>RTAUDIO_INPUT_OVERFLOW:</em> Input data was discarded because of an overflow condition at the driver.</li>
|
