waveform-playlist

waveform-playlist is a multitrack audio editor and player built for the web, enabling users to visually arrange, cue, fade, and shift multiple audio tracks using canvas waveform previews. It’s designed for developers and audio enthusiasts who need a browser-based tool for recording, annotating, and mixing audio, with the ability to export mixes as AudioBuffers or WAV files and integrate effects via Tone.js. Inspired by Audacity, it’s interesting because it brings professional-grade, real-time multitrack editing directly into the browser without requiring external software.
