Audio Feedback & Project Management

Stacktune provides secure collaboration spaces for your audio projects that enable you to manage all your data in a centralized place. Whether it's sharing the newest mix or master with clients, distributing rehearsal recordings to your bandmates, or sending your song to promoters, managers, and record labels - Stacktune has you covered.
Managing feedback and tracking to-do items becomes a breeze with timestamped comments. And for daily tasks like comparing different versions, Stacktune ships with a multitude of helpful tools, like level matching.
Capture precise feedback with time-stamped comments
Whether it's a point in time, a region or a general comment, Stacktune is the perfect tool for your clients and bandmates to submit precise feedback or changes. No more guessing what someone is talking about.


All your files and feedback in one place
Keep track of each version of songs in your projects - and all the comments and requests. Everything well organized in one place, and with email notifications, you'll never miss a beat.

Comparing audio files never has been that easy
Don't waste your time doing repetitive work. We automate all the time-consuming tasks like level matching and aligning versions, making it easy to compare different mixes reliably. Figuring out the differences between versions 3 and 5? Eliminate the guesswork with Stacktune.


Keep track of all your progress
Comments and feedback turn into an automatically updating to-do list, so you always know what needs to be done to finish a project. When selecting a song or version, the list also focuses on relevant items only.
Collect feedback from anyone - without all the hassle
Public Version Pages enable you to collect feedback without the need to invite members to your project. Simply share a link using your favorite messenger or social media. Anyone who knows the link can leave feedback - even if they don't have a Stacktune account.
