<div class="textblock"><p>Generic container for audio samples. </p>
<p>This is the main container structure for audio data. The data are stored in unions, so you can access the matching pointer type without the need for casts. If you have noninterleaved channels, the i'th channel will be in channels[i].f (if you use floating point samples). For noninterleaved formats, use the samples member. valid_samples must be set by the source to the number of actually valid samples in this frame.</p>
<p>Audio frames are created with <a class="el" href="group__audio__frame.html#ga9a0679da671cfc38a1d1a8e39c404944">gavl_audio_frame_create</a> and destroyed with <a class="el" href="group__audio__frame.html#ga194da819036369ca914a8479a70a4c09">gavl_audio_frame_destroy</a>. The memory can either be allocated by gavl (memory aligned) or by the caller. </p>
