Interface: VisualizerDecodeState

Defined in: packages/player/src/visualizer.ts:295

Per-subscription state the smoothing and the auto-gain need between frames.

Kept explicit (rather than hidden in a closure) so the decode step stays a pure function of (capture, options, state) and is trivially testable.

Properties​

gainDb​

gainDb: number;

Defined in: packages/player/src/visualizer.ts:307

Current auto-gain offset in dB; 0 until the first non-silent frame.

peakHold​

peakHold: Float32Array;

Defined in: packages/player/src/visualizer.ts:303

Frames each cap still hangs before it starts falling.

peaks​

peaks: Float32Array;

Defined in: packages/player/src/visualizer.ts:299

Current peak-hold cap per band.

peakVelocity​

peakVelocity: Float32Array;

Defined in: packages/player/src/visualizer.ts:301

Downward velocity of each cap, accumulated by gravity.

plan?​

optional plan?: BandPlan;

Defined in: packages/player/src/visualizer.ts:309

Cached band geometry, rebuilt only when it actually changes.

power​

power: Float32Array;

Defined in: packages/player/src/visualizer.ts:305

Scratch for per-band power, reused so decoding allocates nothing.

smoothed​

smoothed: Float32Array;

Defined in: packages/player/src/visualizer.ts:297

Previous smoothed band values; grown/reset when bands changes.
