@soundtouchjs/interpolation-strategy-lanczos

Lanczos 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 { registerLanczosStrategy } from '@soundtouchjs/interpolation-strategy-lanczos';

registerLanczosStrategy({ registerInterpolationStrategy });

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

st.setInterpolationStrategyParams({ zeroCrossings: 6 });

Params

• zeroCrossings (default 4, normalized to 2..8)
• normalize (default false) — when true, kernel weights are normalized so they sum to 1
