Key + BPM from any audio on your Mac
I built Session Key to instantly find the key and BPM of anything playing on your Mac, samples, references, loops, YouTube, Spotify, voice memos, whatever.Tommy Rush
Fully private: the audio never leaves your Mac. All key and BPM detection runs entirely on-device.
Being built in the same sessions as the records.
Leave your email and you're first in the room when it ships. No spam, just the launch.
It lives in your menu bar, listening to your system audio and telling you the key and BPM of whatever's playing.
Samples, references, loops, YouTube, Spotify, voice memos, whatever. If your Mac can play it, Session Key can read it.
Real-time detection straight from your system audio. The key and tempo appear the moment the music starts.
Always one click away. The audio you play never leaves your Mac, and detection runs on-device.
