Stem Tracks
Three steps to collaborative music
From a song you love to a fully original recording owned by your group.
Buy, Import & Separate
Purchase a song on iTunes or Apple Music. Import it into the free PanEcho macOS app and separate it into stems — entirely offline on your Mac.
Practice & Record
Record your part against isolated stems — any instrument, voice, or electronic performance. Upload your lossless recording to the group when you're done.
Collaborate & Complete
Group members vote on each contribution. When all stems are replaced, you have a fully royalty-safe cover — zero copyrighted audio ever stored.
No copyrighted audio. Ever.
PanEcho never hosts, transmits, or stores any original copyrighted audio. Stem separation runs 100% locally on your machine. Only your original recordings reach our servers.
- Local-only stem separation via PanEcho desktop app

- DMCA takedown process for violations

100% Original Output
Every completed group produces a song made entirely of original recordings. No AI generation, no samples — just real musicians playing real instruments.
