Struct AudioMixer 

pub struct AudioMixer { /* private fields */ }

Multi-channel audio mixer with fixed-point arithmetic

Implementations

impl AudioMixer

pub fn new(sample_rate: u32, channels: u8) -> Self

Create a new audio mixer

Arguments

• sample_rate - Output sample rate in Hz (e.g., 48000)
• channels - Number of output channels (1=mono, 2=stereo)

pub fn add_channel(&mut self, name: &str) -> u16

Add a new mixer channel and return its ID

pub fn remove_channel(&mut self, id: u16)

Remove a mixer channel by ID

pub fn set_volume(&self, channel_id: u16, volume: u16)

Set volume for a specific channel (0..65535)

pub fn set_master_volume(&self, volume: u16)

Set the master volume (0..65535)

pub fn get_master_volume(&self) -> u16

Get the master volume (0..65535)

pub fn mix_to_output(&mut self, output: &mut [i16])

Mix all active channels into the provided output buffer

For each sample position, reads from all channels, applies per-channel volume and mute, sums with saturation, then applies master volume. The result is written directly to output.

pub fn channel_count(&self) -> usize

Return the number of active channels

pub fn get_channel_mut(&mut self, id: u16) -> Option<&mut MixerChannel>

Get a mutable reference to a channel by ID

pub fn write_channel_samples(&mut self, channel_id: u16, samples: &[i16])

Write samples to a specific channel
