AUDIOT

Simple wrapper around ffmpeg to combine and merge audio clips.

Installation

npm install audiot --save

Usage

import { compile } from 'audiot';
import type { Timeline } from 'audiot';

const timeline: Timeline = [
  { file: '1.mp3', start: 1000, speed: 1 },
  { file: '2.mp3', start: 6000, speed: 0.75 },
];

const {stdout, stderr} = await compile(timeline, 'output.mp3');

The start property is the time in milliseconds to start the audio clip (default to 0). The speed property is the speed of the audio clip (default to 1). A speed of 1 is normal speed, 0.5 is half speed, and 2 is double speed etc.

The compile function will merge the audio clips in the timeline and save it to the output file. The returned promise contains stdout and stderr from the ffmpeg process.
