DefaultMixBus

khora_core::audio::mix_bus

Struct DefaultMixBus 

Source 
pub struct DefaultMixBus { /* private fields */ }
Expand description

Mutex-backed ringbuffer impl of AudioMixBus.

Lives in khora-core so apps and tests can construct one without pulling khora-infra. Performance is adequate for early development; migration to a lock-free queue is a follow-up PR.

Implementations§

Source§

impl DefaultMixBus

Source

pub fn new(info: StreamInfo, capacity_frames: usize) -> Self

capacity_frames is the high-water mark in frames (not samples). Samples beyond that are dropped from the head — newest wins.

Trait Implementations§

Source§

impl AudioMixBus for DefaultMixBus

Source§

fn stream_info(&self) -> StreamInfo

Channel count and sample rate negotiated with the device. Read more
Source§

fn write_block(&self, samples: &[f32])

Push interleaved PCM samples produced by an audio lane. Read more
Source§

fn pull(&self, out: &mut [f32])

Drain the next out.len() samples into the hardware output buffer. Called from the audio backend’s callback thread. Read more

impl<T> Any for T
where T: 'static + ?Sized,

Source§

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more
