Berlin Pulse
Add music or sound
Upload from your computer, pick a demo, paste a media URL, or load an M3U/M3U8 playlist. Everything mixes into the master bus and drives the live analyser below.
Upload from your computer
Drop audio or video files here, or click below to pick.
Use demo sounds
Quick-start a session with a bundled loop or hit.
Demo files live in static/audio/demo/ — if a card errors, drop the matching mp3/wav into that folder and reload.
Paste a stream or media URL
Direct mp3 / wav / mp4 / webm work straight away. CORS-locked sources will say so.
Paste a playlist (M3U / M3U8)
Drop in a playlist body — entries are parsed and shown below to pick from.

Notes
- No autoplay. Every entry point only starts audio after you click — required by browsers.
- Tab / system audio uses the screen-share picker. Pick a tab and tick "Share tab audio" (Chromium) or a window with audio.
- CORS: external mp3 URLs work only when the server returns
Access-Control-Allow-Origin. The friendly error tells you when this is the cause. - Uploads stay local — files never leave your browser. Object URLs are revoked when you remove the source.
- Mic constraints: echoCancellation / noiseSuppression / autoGainControl are off so the analyser sees raw levels.
