AudioMixer

Struct AudioMixer 

Source
pub struct AudioMixer {
    channels: u8,
    mic_queue: VecDeque<f32>,
    sys_audio_queue: VecDeque<f32>,
}
Expand description

Two-source audio mixer. Both inputs must use the same sample rate + channel count as the configured output.

Fields§

§channels: u8§mic_queue: VecDeque<f32>§sys_audio_queue: VecDeque<f32>

Implementations§

Source§

impl AudioMixer

Source

pub fn new(channels: u8) -> Result<Self, MixerError>

Construct a new mixer for the given channel count.

§Errors

Returns MixerError::ZeroChannels if channels == 0.

Source

pub fn push_mic(&mut self, samples: &[f32]) -> Result<(), MixerError>

Push interleaved F32 mic samples. samples.len() must be a multiple of channel count.

§Errors

Returns MixerError::UnalignedSamples on misalignment.

Source

pub fn push_sys_audio(&mut self, samples: &[f32]) -> Result<(), MixerError>

Push interleaved F32 system-audio samples. Same alignment contract as Self::push_mic.

§Errors

Returns MixerError::UnalignedSamples on misalignment.

Source

pub fn pull(&mut self) -> Vec<f32>

Drain whatever’s currently mixable + return the merged interleaved samples.

Length = min(mic_avail, sys_avail) when both are active; mic_avail when only mic is pushing; sys_avail when only system-audio is pushing; 0 when neither has anything.

Always returns a sample count that’s a multiple of channel count.

Source

pub fn mic_queued(&self) -> usize

Bytes currently queued from the mic input (sample count, not byte count — multiply by 4 for F32 byte length).

Source

pub fn sys_audio_queued(&self) -> usize

Bytes currently queued from the system-audio input.

Source

pub fn channels(&self) -> u8

Output channel count this mixer was configured with.

Source

fn validate_alignment(&self, sample_count: usize) -> Result<(), MixerError>
