@soundtouchjs/interpolation-strategy-blackman

Blackman interpolation strategy plugin for SoundTouchJS.

I accept cash if you like what's been done.

Part of the SoundTouchJS monorepo — for more information and so much more.

Usage

import { registerInterpolationStrategy, SoundTouch } from '@soundtouchjs/core';
import { registerBlackmanStrategy } from '@soundtouchjs/interpolation-strategy-blackman';

registerBlackmanStrategy({ registerInterpolationStrategy });

const st = new SoundTouch({
  interpolationStrategy: 'blackman',
});

st.setInterpolationStrategyParams({ zeroCrossings: 6 });

Profile

Better stopband rejection than Hann with a slightly wider transition band.

Params

• zeroCrossings (default 4, normalized to 2..8)
• normalize (default false) — when true, kernel weights are normalized to sum to 1
• alpha (default 0.42), beta (default 0.5), gamma (default 0.08) — Blackman window coefficients for advanced window shape control
