Six years alongside Vietnam's music-makers, and a rewrite from scratch
The old separation tool ran from 2020, slowed down over the years and even displayed visitors' IP addresses publicly. TachNhac is the answer: a complete rewrite, privacy first, going deep on exactly one job instead of sprawling.

What is TachNhac?
TachNhac is a platform built for separating and cleaning up audio. One place covers vocal removal, noise removal and applause removal, plus basic processing tools such as an audio cutter and a spectrogram viewer.
Is TachNhac free?
Yes. Every tool that is open today is free and needs no account. Signing in only saves your activity history so you can re-download past results. A premium tier using Energy (E) will come later, but the free tier stays.
Are my files made public?
No. Unlike the old tool that publicly showed users' IP addresses, TachNhac never exposes your data. Only you can see your own activity history.
