AI mastering

AI mastering takes a finished mix and rebalances loudness, frequency and dynamics to produce a track that sounds louder, tighter and more even, the same final step a track gets before release. Upload the mix, the AI processes it, download the mastered file. The tool is still being built and is not open to users yet.

What is mastering?

Mastering is the final processing stage a track goes through, after mixing and immediately before release. It no longer touches individual instruments; it works on the finished stereo mix, with three goals. First, correcting the overall frequency balance so the song holds up everywhere, from a phone speaker to headphones to a car system. Second, bringing the overall loudness to the level streaming platforms expect, so your track does not sit noticeably quieter than the one before it in a playlist. Third, tightening the dynamic range just enough that the track feels solid without losing room to breathe. AI mastering does those three things automatically, by comparing your mix against the characteristics of a large body of released tracks in the same genre.

Can AI mastering fix a bad mix?

No. Mastering is the final processing layer, applied after the mix, not a replacement for it. If the original has serious frequency imbalance, a buried vocal, or technical issues like clipping, AI mastering just makes those problems louder rather than fixing them: garbage in, garbage out, only bigger.

How is AI mastering different from a human mastering engineer?

AI applies a data-driven processing chain, fast and consistent, which suits demos, social posts and quick listening copies. A human engineer can hear context, genre conventions and artistic intent and make judgment calls the AI cannot yet make. For a genuine commercial release, human mastering is still the safer choice.

When should you use AI mastering?

When the mix is already solid and you need a fast finishing pass: a demo for a label, a rough copy to listen back on, or social content that needs to sit at a competitive loudness. If the mix itself is still being fixed, finish that first: mastering is a final polish step, not a repair step.

How is mastering different from audio enhancement?

They assume two different kinds of input file. Mastering assumes the mix is already good, everything is in its place, and all that remains is finishing it for release. Audio enhancement assumes the opposite: the recording has problems, the voice is dull, there is distortion, the level is low, and it needs rescuing. Running a phone recording through mastering will not save it, it will only make every flaw evenly louder. Running a finished mix through an audio enhancer is equally wrong, because an enhancer processes for speech clarity rather than release standards. Tách Nhạc keeps these as two separate tools for exactly that reason, and choosing between them is simple: ask whether your file needs finishing or needs rescuing.

Who needs AI mastering?

• Independent musicians who need a release-ready file for streaming platforms
• Artists preparing demos for labels or quick listening copies
• Content creators who need background music at a consistent, competitive loudness
• Anyone without the budget to hire a mastering engineer for every rough draft
• Producers who want to preview their mix at release-level loudness before committing to real mastering

The tool is not open yet. These are the steps it is being built to have.

1. 1

   Upload the finished mix

   Submit the final mix, ideally an uncompressed WAV with headroom left (peaks around minus 6 dB).

2. 2

   Choose a mastering direction

   Pick the profile that matches the genre and the destination, for example loud and tight for streaming platforms, or a lighter hand for acoustic material.

3. 3

   Compare at matched loudness

   A/B the original and the master at the same volume. The louder version always sounds better, so an unmatched comparison tells you nothing.

4. 4

   Download the master

   Export the mastered file. If it is not right, fix the mix and run it again rather than stacking master passes.

• Mastering cannot fix a mix. A buried vocal or a muddy low end has to go back to the mix stage.
• A mix that is already heavily compressed leaves very little dynamic range to work with, and the result usually sounds choked and fatiguing.
