Struct web_audio_api::alloc::AudioBuffer

pub struct AudioBuffer { /* fields omitted */ }

Fixed length audio asset, basically a matrix of channels * [f32; BUFFER_SIZE]

An AudioBuffer has copy-on-write semantics, so it is cheap to clone.

Implementations

impl AudioBuffer

pub fn new(channel: ChannelData) -> Self

pub fn number_of_channels(&self) -> usize

Number of channels in this AudioBuffer

pub fn set_number_of_channels(&mut self, n: usize)

Set number of channels in this AudioBuffer

Note: if the new number is higher than the previous, the new channels will be filled with garbage.

pub fn channel_data(&self, index: usize) -> &ChannelData

Get the samples from this specific channel.

Panics if the index is greater than the available number of channels

pub fn channel_data_mut(&mut self, index: usize) -> &mut ChannelData

Get the samples (mutable) from this specific channel.

Panics if the index is greater than the available number of channels

pub fn channels(&self) -> &[ChannelData]

Channel data as slice

pub fn channels_mut(&mut self) -> &mut [ChannelData]

Channel data as slice (mutable)

pub fn mix(
    &mut self,
    computed_number_of_channels: usize,
    interpretation: ChannelInterpretation
)

Up/Down-mix to the desired number of channels

pub fn make_silent(&mut self)

Convert this buffer to silence

pub fn force_mono(&mut self)

Convert to a single channel buffer, dropping excess channels

pub fn modify_channels<F: Fn(&mut ChannelData)>(&mut self, fun: F)

Modify every channel in the same way

pub fn add(&mut self, other: &Self, interpretation: ChannelInterpretation)

Sum two AudioBuffers

If the channel counts differ, the buffer with lower count will be upmixed.

Trait Implementations
