Five features, all in one place
Built by a working musician to make practice easier.
11-stem Separation
Hear through the mix.
Vocals, bass, guitar, piano, and drums, split six ways: kick, snare, toms, hi-hats, ride, and crash. Separation paired with slowdown that stays clear.
Language library
Never forget a lick.
What was that out lick that Herbie played comping behind Miles, on Live at the Plugged Nickel? One click in your personalized language library takes you back to that exact moment, so you can easily jump back into internalizing the language.
smart looping
Loops that lock in with the band.
Hit loop and get a perfect bar—boundaries locked to the recording's real grid, even when the tempo fluctuates. No more wrestling with Ableton warp markers, nudging loop points by hand.
One-shot sampling
Sampling made easy for producers.
The easiest way to collect and organize drum one-shots: select a drum transient then right click to save it in your samples folder.
metronome
Load grooves into your metronome.
Standard metronome, plus every groove that you save into your groove library. Stop switching between the google metronome, Drum Genius, and scattered Ableton and logic sessions when you’re practicing time.
One click to change between Tony Williams, Dilla, Church loops, and a basic click.
The whole mix, separated.

Questions
What are the system requirements?
A Mac with Apple Silicon (M1 or newer) running macOS 13 or later. Practice Room is built native for Apple Silicon. I wrote this app specifically leveraging the Apple silicon ecosystem.
How does the free trial work?
The app includes a 14-day full-featured trial — open it and everything works, no account, no credit card. When you buy, your license key arrives by email; paste it into the app and it works forever offline.
Is my audio uploaded to the cloud?
No. Analysis, separation, and playback all happen on your Mac. The app works fully offline - internet is only used for license activation and optional downloads.
How many Macs can I use it on?
Your license activates on up to 2 Macs. You can deactivate a machine any time to free a slot.
What about refunds?
If it's not working well for you, write within 14 days of purchase and we'll refund you — but just give the 14-day trial a shot first.
Who makes this?
I’m Nathan Suh - a working jazz and R&B musician, songwriter, and multi-instrumentalist. I wrote this app to make my life easier, after spending years in the practice room, annoyed at clunky technology. I just finished up school at Berklee College of Music in Boston, and I used to be a Machine Learning engineer working for startups in San Francisco.
