Opusonix is a web-based platform (with a free tier) designed to simplify mix reviews, client collaboration, and project management for producers and audio engineers.
At its core, Opusonix brings all the moving parts of a typical mix project, like audio tracks, feedback, revisions, and task lists, into a single, organized workspace.
So, if you’re working with multiple clients or collaborating with friends, it can help streamline your workflow. Instead of juggling dozens of email threads, cloud links, and spreadsheets, you can handle everything from version control to communication in one place.
The idea behind this one is straightforward. It’s basically designed to make collaboration in audio production as efficient as it is in other creative fields (and it’s no secret that we producers are known for not being the best at organizing stuff, probably due to having folders full of projects with filenames like “Song 4 (better mix) MASTERED – Final FINAL V9 October 2025.WAV”).
Within each project in Opusonix, you and your collaborators can upload audio files (compressed or uncompressed). There’s 1 GB of storage available in the free tier, and the Pro plan includes 200GB of data for file exchange (not just audio files), which is sufficient for most engineers/producers to handle their file exchange needs without involving a 3rd-party service.
Once the audio files are uploaded, you can leave timestamped comments directly on the waveform, or even record voice notes that automatically generate transcriptions.
Each comment is threaded, which means that all project notes, questions, and replies stay contextual and easy to follow.
One of my favorite features in Opusonix is how it handles mix versions and A/B tests. You can upload multiple mixes, compare them instantly, and tag the current “primary” version.
This workflow helps clarify which version a client is referencing, which is an issue that traditionally causes endless confusion during remote mix revisions.
For album projects, the Album Planner offers a broader view. It lets you manage multiple tracks, test running orders, and evaluate the full album flow in real time.
Producers working on multi-track projects or recurring clients can also use custom project templates to define review stages, mix checklists, and deliverable formats, which makes it easy to stay consistent from one project to the next.
Beyond audio review, Opusonix integrates task management and scheduling tools directly into the workspace. The built-in Kanban board lets you visualize progress, while tasks created from feedback automatically sync with a project calendar.
Using natural language processing, Opusonix can turn comments like “fix vocals by Friday” into actionable tasks with due dates.
Collaboration works both in real time and asynchronously. You can host live review sessions or let clients log in later to leave notes, which makes the platform equally useful for studio engineers, remote mixers, and post-production teams.
Security is handled through encrypted cloud storage, and file access is granted via time-limited private links. Opusonix supports all standard audio formats (WAV, MP3, M4A, AIFF) and allows file uploads for stems, scores, or session folders.
Opusonix is available now as a web app with a free tier (1 GB storage, 10 projects) and a Pro plan ($9.99/month) offering 200 GB of storage, templates, and AI summaries. You can try the Pro version free for seven days at the official website.
