Key & BPM Lab
Private audio tools for musicians, DJs and creators
Find a song's key and BPM, change pitch or tempo, cut and join audio, tap a beat and practice with a metronome. Free private browser audio tools.
Hey Product Hunt 👋
We built Key & BPM Lab because working with a song often means jumping between several apps: one to find the BPM, another to detect the key, another to change the tempo, and yet another to trim or export the result.
We wanted to bring those everyday music tasks into one focused browser workspace.
With Key & BPM Lab, you can:
🎵 Detect BPM, musical key, scale and Camelot code
🎚️ Change pitch and tempo independently
✂️ Cut, fade, arrange and join audio
🥁 Tap a tempo or practice with a precise metronome
🎙️ Record audio directly in your browser
🤖 Remove vocals, split stems, enhance audio and convert melodies to MIDI with AI
Most of the core tools run locally on your device. That means supported files can be analyzed, edited and exported without being uploaded to our servers. When a tool requires cloud AI processing, we explain that clearly before the job starts.
The essential browser tools are free and do not require a subscription. AI tools use flexible credits for heavier processing.
We’re launching today to learn from musicians, DJs, producers and creators:
1. Which audio workflow should we improve next?
2. What tool is still missing from your current setup?
3. Where does the experience feel confusing or slow?
Thanks for checking out Key & BPM Lab. We’ll be here throughout the launch and would love your honest feedback.
