Virtual rehearsal studio with instant performance feedback
Free browser practice studio that hears you play — vocal pitch training, vocal range tests, karaoke with live scoring, and guitar, piano and drum rooms that show every note you hit.
As a bedroom musician, I was frustrated by how fragmented practicing felt. I wanted to visualize my vocal pitch, isolate audio stems, read lyrics, and track my progress without juggling multiple clunky desktop apps.
To solve this, I built MercuryPitch: a free, open-source, in-browser rehearsal studio. The live pitch analysis runs entirely on-device, ensuring minimal latency and complete privacy.
Here is what you can do without downloading anything:
Drop in any song to isolate stems (vocals, backing, piano, drums, bass, and guitar) using deep learning models, and automatically sync lyrics to the melody.
Practice in dedicated Karaoke, Piano, Guitar, or Drum rooms with live visual feedback and session scoring.
Connect via peer-to-peer video Jam Rooms for live remote practice or teaching.
Review your recorded takes in the 'Hear Yourself' dashboard and train your ear in the Ear Lab Room.
Share your melodies, take on community challenges, and climb the leader boards
Launch Offer: While the core app and local processing are 100% free, we utilize premium cloud-based neural networks for our highest-fidelity stem separation. Use the promo code PRODUCT_HUNT when you sign up to get 5 free premium stem separation credits.
The repository is fully available on GitHub. I'll be here all day answering questions—let me know what instrument you play and what features you'd like to see added next!
P.S. separating a song into piano, drums, guitars and bass requires server side processing as the models are more complex, so use the free credits from this launch to try the full band split!
