I wanted to share a quick update on Opusonix (https://opusonix.com), a fairly new mix review and collaboration platform that’s been steadily evolving since launch. It’s developed by a very small team, but it’s been encouraging to see it gaining traction and positive feedback from engineers, producers, and composers.
Over the past few weeks, Opusonix v1.6 added several workflow-focused features:
- Powerful A/B mix comparison
Loudness-matched playback (see it in action: )
Custom sync markers (useful for comparing different sections or referencing other tracks) - Improved mobile experienceMore phone-friendly UI and smoother navigation
- Fast project switching & deep searchJump to any project with a few keystrokes
Search now includes track comments, so you can instantly find and jump to specific feedback - Conversational Notes
A living document attached to each track project to keep context, decisions, and conversations in one place - Ownership transfer
Easily hand off full control of a track workspace to a client or collaborator when a project is complete

If you’re starting a new track and want a cleaner way to review mixes, compare revisions, and keep communication organized, you’re very welcome to give it a try. Feedback is always appreciated — it’s still early days, and the platform is shaped heavily by real-world use.
Thanks for taking a look: https://opusonix.com
