@soundtouchjs/interpolation-strategy-hann

Hann 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 { registerHannStrategy } from '@soundtouchjs/interpolation-strategy-hann';

registerHannStrategy({ registerInterpolationStrategy });

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

st.setInterpolationStrategyParams({ zeroCrossings: 6 });

Profile

Good general-purpose quality with moderate roll-off.

Params

• zeroCrossings (default 4, normalized to 2..8)
• normalize (default false) — when true, kernel weights are normalized to sum to 1
• windowPower (default 1) — exponent applied to the Hann window shape; values above 1 sharpen the window
