Struct DspContext

pub struct DspContext {
    pub sample_rate: f64,
    pub num_channels: usize,
    pub buffer_size: usize,
    pub current_sample: u64,
    pub channel_layout: ChannelLayout,
}

Runtime context passed to blocks during audio processing.

Contains the audio specification (sample rate, channels, buffer size) and the current playback position. This context is passed to every block’s process() method, allowing time-dependent calculations.

Fields

sample_rate: f64

The audio sample rate in Hz (e.g., 44100.0, 48000.0).

num_channels: usize

The number of output channels (e.g., 2 for stereo).

buffer_size: usize

The number of samples processed per block.

current_sample: u64

The absolute sample position since playback started. Increments by buffer_size after each process cycle.

channel_layout: ChannelLayout

The channel layout for audio processing. Describes the speaker/channel configuration (stereo, surround, ambisonics).

Trait Implementations

impl Clone for DspContext

fn clone(&self) -> DspContext

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
