Environment independent library to create and read .bwcurve files.
npm install bwcurve.tsNOTE: Until this package gets to 1.0.0 it will not follow SemVer, the API _will_ change suddenly without any warning. Only use this package if you are fine with that.
BWCurve.ts is a Browser and Node.js compatible TypeScript library to read, write and modify Bitwig Studios .bwcurve format. Reading .bwcurve is not yet supported, but will be added as soon as possible.
Basic Usage:
``ts
import { BWCurve } from 'bwcurve.ts';
const curve = new BWCurve()
.setCreator('Alice')
.setCategory('Envelope')
.setName('My Curve')
.setTags(['tag1', 'tag2'])
.setPoints(
[
{ x: 0, y: 0, slope: 0 },
{ x: 1, y: 1, slope: 0 },
],
(p) => p
)
.toBuffer();
// save the file if you're in node, download the file if you're in the browser
`
Converting wav files:
`ts
import { BWCurve } from 'bwcurve.ts';
// ensure that the file is mono, or select a specific channel
const { channelData } = wavReader('path/to/file');
const curve = new BWCurve()
.setCreator('Alice')
.setCategory('Envelope')
.setName('My Curve')
.setTags(['tag1', 'tag2'])
.setPoints(channel_data, (sample, idx, array) => {
return {
x: idx / array.length,
y: Math.max(0.0, Math.min(1.0, y * 0.5 + 0.5)),
slope: 0,
};
})
.clamp()
.fitInXRange(0, 1)
.toBuffer();
// save curve to file
