Shared visualization buffer between audio and render threads.

Fields

samples: AtomicRingBuffer

PCM stereo interleaved samples.

fft_bins: AtomicRingBuffer

FFT magnitude bins.

rms_left: AtomicF32

RMS levels (300ms integration window).

rms_right: AtomicF32

peak_left: AtomicF32

Peak levels (1.7s hold, then decay).

peak_right: AtomicF32

phase_correlation: AtomicF32

Phase correlation coefficient (-1.0 to 1.0).

audio_clock_us: AtomicU64

Audio thread clock (microseconds since start).

game_tick_us: AtomicU64

Game tick clock (microseconds since start).

active_lane: AtomicU8

Active lane indicator (0=game, 1=mixer, 2=file).

underrun_count: AtomicU32

Buffer underrun counter.

Implementations

impl AudioVizBuffer

pub fn new(sample_capacity: usize, fft_capacity: usize) -> Self

pub fn compute_and_store_rms(&self, window: usize)

Compute RMS from the last window stereo interleaved samples. Called by audio thread after writing samples.

pub fn update_peak_hold(&self)

Update peak hold with decay. Called by audio thread.
