Notes on the waveform
Put the note where the problem is
Click the waveform and your comment is pinned to that point in the track, down to the millisecond. Nobody has to work out what “around two minutes in” means.
For anyone who works with audio
Upload your stems, click the spot on the waveform you're talking about and leave a note. Everyone else on the project sees it straight away and can reply.

Notes on the waveform
Click the waveform and your comment is pinned to that point in the track, down to the millisecond. Nobody has to work out what “around two minutes in” means.
Live sessions
You can see who's in the project, and new notes show up as they're written. Reply while the idea's still fresh instead of waiting for a call back.
Full-quality files
Send full-quality WAVs with no compression. They go straight to the cloud and are ready to play in a few seconds, so nobody asks you to send that file again.
Revisions
Each upload sits in a project and a revision, so it's always clear which bounce is the latest. Comments stay attached to the version they were written on.
Uploading a stem and leaving a few notes on it, start to finish.
Drop in a mix, a bounce or all the stems. You can play it as soon as it's up.
Click anywhere on the waveform and type what you heard.
People reply under each note, and you mark it resolved once it's fixed.
Send a beat or a rough mix and get comments on the actual bars. Every version and every note stays in one project, not spread across five chats.
Listen to your part on its own or in the full mix, and mark anything that needs another take. Works on your laptop or your phone.
Share the arrangement once and the band's notes come back on the bars they're about. Rehearsal can start with the fixes already sorted.
Whether it's mixing, mastering, broadcast or post, you get notes with a timestamp on them rather than an email you have to decode.
iPhone and iPad
Hold your finger on the waveform and slide to the right spot before you comment. Handy at rehearsal or on the way home from one.
Coming soonThe free plan gives you 5 stems per revision and 2 GB of storage. If your sessions get bigger, Pro and Elite give you more stems, more space and version history.

Only people you've invited to the project, plus anyone you send a preview link to.
The iPhone and iPad app is coming soon. For now you can use STEMR in the browser on your phone.
Yes, whenever you like, from Settings. You keep your plan until the end of the period you've paid for, then you move back to Core.
Start a project, upload a stem and send the link to whoever you'd normally ask.
