pub struct AudioBuffer { reflector_: Reflector, js_channels: DomRefCell<Vec<HeapBufferSource<Float32>>>, shared_channels: DomRefCell<Option<AudioBuffer>>, sample_rate: f32, length: u32, duration: f64, number_of_channels: u32, }
Expand description

The AudioBuffer keeps its data either in js_channels or in shared_channels if js_channels buffers are detached.

js_channels buffers are (re)attached right before calling GetChannelData and remain attached until its contents are needed by some other API implementation. Follow https://webaudio.github.io/web-audio-api/#acquire-the-content to know in which situations js_channels buffers must be detached.

Fields§

§reflector_: Reflector§js_channels: DomRefCell<Vec<HeapBufferSource<Float32>>>

Float32Arrays returned by calls to GetChannelData.

§shared_channels: DomRefCell<Option<AudioBuffer>>

Aggregates the data from js_channels. This is Some<T> iff the buffers in js_channels are detached.
