Web based multitracks audio editing

I need an audio sequencer like soundtrap.com made in javascript/HTML/CSS, it should be made using plain vanilla JS or eventually react js. details will be discussed later. deadline is within 2 weeks or 3 weeks MAX.

Basic features I need:
- timeline
- multitracks
- SVG waveform from audio file imported
- drag and drop
- audio levels adjustments
- audio effects for every track
