Expand description

A resource of audio samples.

Required Methods§

Source

fn num_channels(&self) -> NonZeroUsize

The number of channels in this resource.

Source

fn len_frames(&self) -> u64

The length of this resource in samples (of a single channel of audio).

Not to be confused with video frames.

Source

fn fill_buffers( &self, buffers: &mut [&mut [f32]], buffer_range: Range<usize>, start_frame: u64, )

Fill the given buffers with audio data starting from the given starting frame in the resource.

buffers - The buffers to fill with data. If the length of buffers is greater than the number of channels in this resource, then ignore the extra buffers.
buffer_range - The range inside each buffer slice in which to fill with data. Do not fill any data outside of this range.
start_frame - The sample (of a single channel of audio) in the resource at which to start copying from. Not to be confused with video frames.
