Euphona's stem separation isn't one split that gets recombined - it's four separate models: 2 stems (vocals / instrumental), 4 (vocals, drums, bass, other), 5 (adds piano) and 6 (adds guitar). Stems come back at the source sample rate, up to 192 kHz, 24-bit or 32-bit float.
Our own advice on the site is to use the fewest stems that answer your question: two if you just need an instrumental, six only if there's a real guitar part worth isolating.
I'd like to know whether that matches how you actually work. When you pull a track apart, what are you after - a clean acapella, a drum bus to re-balance, something else?

Hi Product Hunt ๐
I'm the founder of Euphona. I trained as a musicologist before becoming a software engineer, and I kept running into the same problem: every audio tool starts from a fresh bounce. You master in one app, separate stems in another and clean up noise in a third, and none of them knows what the others did.
Euphona fixes that with one engine. Upload a mix, a stem folder or a raw take. One analysis pass builds the Track Graph: loudness and dynamics over time, spectral balance, key and tempo, and where the audio is damaged. Every tool then reads from it and writes back to it:
๐ AI Mastering: streaming-ready loudness, with every move explained
๐ Stem Separation: up to six stems
๐งน Audio Restoration: removes noise, clicks, clipping and room sound
๐ค AI Vocal Tuning: fixes pitch, timing and tone without artefacts
๐ง AI Mixing and Spatial Audio: builds a mix from your own stems
This means chaining tools loses nothing. The mastering step knows what the mixing step changed.
Try it on your own song: you get 10 free minutes of the full engine, and the analysis itself is never metered. Compare the result against your original, level-matched, as many times as you want. No card, no trial clock, and you pay only when you download a file.
I'd love your honest feedback: which capability should we push further next?
