Struct claxon::frame::Block
[−]
[src]
pub struct Block { /* fields omitted */ }A block of raw audio samples.
Methods
impl Block[src]
fn empty() -> Block
Returns a block with 0 channels and 0 samples.
fn time(&self) -> u64
Returns the sample number of the first sample in the block.
fn len(&self) -> u32
Returns the total number of samples in this block.
Samples in different channels are counted as distinct samples.
fn duration(&self) -> u32
Returns the number of inter-channel samples in the block.
The duration is independent of the number of channels. The returned value is also referred to as the block size. To get the duration of the block in seconds, divide this number by the sample rate in the streaminfo.
fn channels(&self) -> u32
Returns the number of channels in the block.
fn channel(&self, ch: u32) -> &[i32]
fn sample(&self, ch: u32, sample: u32) -> i32
Returns a sample in this block.
The value returned is for the zero-based ch-th channel of the
inter-channel sample with index sample in this block (so this is not
the global sample number).
Panics
Panics if ch >= channels() or if sample >= len() for the last
channel.
fn into_buffer(self) -> Vec<i32>
Returns the underlying buffer that stores the samples in this block.
This allows the buffer to be reused to decode the next frame. The
capacity of the buffer may be bigger than len() times channels().
fn stereo_samples<'a>(&'a self) -> StereoSamples<'a>
Returns an iterator that produces left and right channel samples.
This iterator can be more efficient than requesting a sample directly, because it avoids a bounds check.
Panics
Panics if the number of channels in the block is not 2.
