Music mastering analysis for independent producers

Visit Website
August 31, 2026 I built Aumixys to make mastering feedback clearer for independent producers.

Hi Indie Hackers,

I’m Jacek, an independent music producer and the founder of Aumixys.

I built it because mastering feedback can be confusing: LUFS, True Peak, dynamics, stereo width and clipping often show up as isolated numbers, without making it clear what to do next.

Aumixys helps independent producers check a track before release and turn those measurements into practical feedback.

It currently focuses on:

- loudness and dynamics

- True Peak and clipping risks

- stereo balance

- a clear mastering report

- before/after comparison where a correction is useful

The goal is not to replace an experienced mastering engineer. It’s to give creators a faster way to understand what is happening in their file before publishing it.

I’d genuinely appreciate feedback from producers and makers here:

What is the most confusing part of checking your own master before release?

    The “what do I actually do with these numbers?” problem feels stronger than the metrics themselves.

    Curious whether producers mainly struggle to interpret the measurements, or whether they already know what they mean but lack confidence in deciding when a master is ready to release.

      That’s exactly the distinction I’m exploring. Most producers can recognize that LUFS, true peak, and dynamics matter, but they often lack confidence in translating those values into a release decision — especially in the context of their genre and intended platform. So the goal isn’t to present more numbers. It’s to turn them into clear, practical guidance: what looks healthy, what may cause problems, what to adjust, and when the master is genuinely ready to release. The “ready to release” decision is probably the more valuable layer.

        That makes sense. I’ll be interested to see how that “ready to release” layer holds up once you have more producers using it.

Most independent producers don't have a fast, clear way to check whether a master is ready for release. I built Aumixys to turn confusing measurements—LUFS, True Peak, dynamics and stereo—into practical feedback, so crea
