Struct MetricsAccumulator 

pub struct MetricsAccumulator { /* private fields */ }

Accumulates per-sample statistics and reduces them to UiMetrics every block.

Used by the audio thread to compute RMS, peak, and tap tube/transformer state. Call accumulate() every sample, then reduce() every block_size samples.

Implementations

impl MetricsAccumulator

pub fn new(block_size: usize) -> MetricsAccumulator

Create a new accumulator with the given block size.

pub fn set_nominal_supply(&mut self, voltage: f32)

Set the nominal supply voltage for sag calculation.

pub fn accumulate_levels(&mut self, input: f64, output: f64)

Accumulate input/output levels for one sample.

pub fn accumulate_stage(&mut self, stage_idx: usize, level: f64)

Record a stage level (call after each WDF stage processes).

pub fn record_stage_solver( &mut self, stage_idx: usize, iterations: u32, residual: f64, converged: bool, )

Record one nonlinear/coupled solver call for a stage.

pub fn record_signal_fault(&mut self, value: f64)

Record a runtime signal fault caught outside normal level metering.

pub fn record_tube(&mut self, tube_idx: usize, plate_current_ma: f32, vpk: f32)

Record tube state (call once per sample or per block).

pub fn record_supply(&mut self, voltage: f32)

Record supply voltage (for sag visualization).

pub fn record_lfo_phase(&mut self, phase: f32)

Record LFO phase (for pulse indicator).

pub fn record_gain_reduction(&mut self, gr_db: f32)

Record gain reduction (for compressor meters).

pub fn is_block_complete(&self) -> bool

Check if a block is complete and ready for reduction.

pub fn reduce(&mut self) -> UiMetrics

Reduce accumulated statistics to UiMetrics and reset for next block.

Call this every block_size samples. Returns the reduced metrics.
