AuDimix is an audio separation editor for taking a finished song and estimating five independently adjustable parts: vocals, drums, bass, piano, and the remaining instruments. It works with a mixed recording rather than the original studio session. AuDimix does not reveal hidden master tracks inside an MP3 or WAV file; it analyzes the audible mixture and reconstructs likely stems that can be muted, emphasized, or exported.
Five-way separation
After a track is imported, AuDimix processes it before the stem controls become useful. The result divides the recording into five fixed categories. A vocal line should move toward the vocal stem, while percussion should move toward drums. Piano and bass have their own channels, and sounds that do not fit those groups collect in the backing-instrument stem.
This arrangement is quick to understand, but it is not the same as opening a multitrack recording. Instruments can share frequencies, reverb, or stereo space. When that happens, part of one sound may remain audible in another stem. A loud guitar under a vocal or a heavily processed drum loop can therefore leave traces after muting. AuDimix gives the user a practical separation, not a promise of isolated studio masters.
Level experiments
Each stem has its own level control. Lowering the vocal stem can create room for rehearsal or a replacement performance. Raising the drums can make the beat easier to study. Muting several parts can expose a bass line or piano passage without changing the length and timing of the imported track.
Live Playback previews the current balance before export. That step matters because a clean-looking set of controls can still produce audible leakage or a hollow mix. Listening through difficult sections first avoids waiting for an export that needs another pass. AuDimix keeps the adjustment simple: it changes the balance of the estimated stems rather than turning the workspace into a full multitrack editor with automation lanes and plug-in chains.
Export choices
AuDimix can write five separate stem files. This route keeps vocals, drums, bass, piano, and other instruments independent for later work in a digital audio workstation. It creates several files and requires the receiving project to align them at the same starting point.
The other route creates one complete mix with the chosen stem levels already applied. That file is easier to play or share, but the balance becomes part of the rendered output. A later editor cannot restore an individually muted stem from that mixed export. Choosing between separate stems and one mix should happen before the user starts a longer production workflow.
Input limits
Common audio containers such as MP3, WAV, and M4A can enter the separation process. File compatibility does not guarantee equal results. Lossy compression, crowd noise, distortion, and dense arrangements give the separation model less clean information than a simple recording. A source that already clips will remain clipped after the parts are divided.
Processing time also comes before useful editing. AuDimix must analyze the song, so a long file or slower computer can delay the first preview. Importing a correct file and waiting for analysis are separate from exporting the final result. Saving one stem or mix does not alter the original recording.
