AudioNote

Annotate your music.
Your notes and timestamps, always yours.

Chrome & Edge · files never leave your device

Two ways to annotate — pin moments, or note the whole track
📂
Pick your files
Select audio files from your machine — MP3, WAV, M4A, FLAC and more. Nothing is uploaded.
▶️
Play & seek
Full player with scrubbing, volume control, and instant seeking to any point in the track
⏱
Mark any moment
Hit M at any point while playing — drop as many markers as you want, each with its own label. Click any marker to jump back.
📝
Annotate tracks
Write freeform notes about the whole track — separate from your timestamp markers, auto-saved as you type
⬇
Export CSV
All your notes and every timestamp — with labels and times — exported as one clean CSV
