Built for working mix engineers

Send mixes. Get feedback. Approve and deliver.

Upload an export. Send a link. Your client leaves timestamped notes on the waveform. You get a checklist. No more copying emails to another checklist. No more wrong timestamps.

You're on the list. We'll be in touch.

The current workflow

Five apps.
Every single revision.

You've mixed the song. The client emails notes. Here's what happens next — before Mix Revision.

Step 01
Open Gmail. Parse the chaos.
Wall of text. Vague references. "Around the 2-minute mark." You're guessing at timestamps before you've even opened Pro Tools.
Step 02
Build a checklist. Manually.
Copy each note somewhere you can track it. Every engineer has a different system. None of them are fast.
Step 03
Work through it. Switch apps constantly.
DAW open, notes open, browser open. Mark things done by hand. Lose your place. Bounce when you think you're done.
Step 04
Send the new version. Start over.
Upload somewhere. Send the link. Wait. New notes arrive in a reply thread — not on the player, not timestamped, not organized.
Repeat until approved — or until someone gives up

How Mix Revision works

Three steps.
One tool.

01
Upload your export
Drag a WAV, AIFF, MP3, or FLAC onto the song page. Creates a new revision automatically. Set it active in one click.The original file is preserved. Always.
02
Send the review link
One persistent URL per song. Never changes. Your client opens it on their phone or laptop — no account, no download, no app.They click the waveform to drop a note. Timestamp is automatic.
03
Work the checklist
Notes arrive as a timestamped task list. Check off as you go. Upload the next version when you're ready. Client sees it on the same link.Loop complete. No app-switching.

From the creator

We built this because I was sick of switching between five apps every time a client sent notes. I wanted one place where the note lands and the checklist is already waiting for me.
