How useWaveform scales bars.

Properties​

floorDb?​

floorDb?: number;

Defined in: display.ts:387

Level mapped to 0 by scale: 'db', in dB relative to the reference. Default -40.

Inherited from​

NormalizeOptions.floorDb

percentile?​

percentile?: number;

Defined in: useWaveform.ts:25

Percentile of the bucket levels used as the reference when reference is not given (see peaksLevel). The reference is taken over the whole analyzed range, so zooming or changing barCount never rescales the waveform. Default 1 (the loudest bucket).

reference?​

reference?: number;

Defined in: display.ts:385

Level that maps to 1. Defaults to the largest magnitude of the input; use peaksLevel for a stable scale across zoom levels and bar counts. Values above the reference are clamped.

Inherited from​

NormalizeOptions.reference

scale?​

scale?: "linear" | "db";

Defined in: display.ts:379

  • linear (default): divide by the reference. Keeps silence at 0 and the proportions between bars.
  • db: decibels relative to the reference, mapped from floorDb…0 dB to 0…1. Brings out quiet passages.
