Opusonix

Which mix is THE mix?

Your mix review shouldn't happen in someone's inbox.

Opusonix is the branded mix workspace that you own - not an email thread they will lose, or a Dropbox folder full of files.

This image shows timestamped comments added on an audio track, and the same track with the same timestamped comments on a smartphone, rendered in a user-friendly way that looks like a chat conversation.

The Confusion-Free
Mix Review Workspace

Every review points at one current version.
All the feedback pinned to the exact moment.
Overall notes, chat, built-in A/B and a clear approval status.

"You can also leave both text or recorded audio comments at whatever timestamp you want on the tracks timeline. That is always a super useful feature [...] I find this so much more helpful than someone’s abstract explanation of where a problem is in a song."
Drew Vandenberg
Editor, the TapeOp Magazine
"Best all-around producer feedback platform for structured project workflow". "If you are working with clients regularly, handling multiple revisions, or managing several music projects at once, [Opusonix] is the most complete option".
Music Feedback Pro
"Opusonix significantly reduces the need for third-party cloud storage and cuts down on email communication. (...) On-track conversations keep feedback precise, and export tools make final delivery straightforward and professional.”

"As your client leaves comments, you can quickly turn them into to-do tasks and add them to a list, to stay on top of what needs to be done on that project. (...) For the price point, nothing really competes with Opusonix Pro."

Fewer Emails
0 %

Manage notes, tasks, files, versions of audio tracks and timestamped feedback all in the same place. No more digging through email threads or guessing which version someone meant.

Fewer Revisions, Avoid Mix Fatigue

With integrated mix notes, on-track comments, and level-matched A/B.

Leave comments right on the mixes, and A/B test mixes with loudness matching.

Branded & Structured Project Intake

There's no such thing as structured intake in an email inbox.
Opusonix lets your clients submit project requests with notes, deadlines and track files.

Collaborate, Share, and Deliver

From working together, to sending off the final mixes.
All in One Workspace.

Share Tracks with Playlists

Emails can't play an album. It can only attach files. An Opusonix playlist sequences your tracks like a Spotify list, so a client hits play and hears the record as a record.

Realtime & Async Collaboration

Opusonix works like Google Docs for audio teams, so you can work with your team in realtime or on your own schedule.

Final Delivery Made Easy

Ready to deliver? Use the Export feature to pack up all assets and send to your client with a single click. Or - transfer ownership of the entire workspace to your clients so they get to keep the project and the revisions.

Give your clients one link that's always current. Not an inbox to dig through.
