Core Features
2 / 4 / 5-stem separation
Pick 2, 4 or 5-stem separation — split vocals from the backing track, or break a song into components such as vocals, backing, bass and drums for karaoke, remixing or practice.
Many formats & YouTube links
Accepts mp3, wav, m4a, mp4, mov, ogg and wma input, or paste a YouTube link directly; up to 200MB per file. Exports mp3 at up to 320kbps.
Free to use, VIP closed to new sign-ups
Existing VIP is still billed at 3 VND per second of file duration (from 720 VND per use), unlocking 320kbps output, model selection and an ad-free view — but the VIP sign-up form has stopped accepting new applicants, and new needs are directed to tachnhac.com. 5 free separations remain to try the tool.
Online processing, installable app
Runs entirely on the web with no software to install; can be installed as an app (PWA) on Chrome, Android and iOS with step-by-step guides.
Deep separation service
Beyond the automated tool, a deep (manual) separation service handles vocal/instrument isolation, video editing and watermark removal; VIP users get 30% off.
Free to try, VIP closed to new sign-ups
The first 5 separations are free. The VIP sign-up form is now closed to new applicants; existing VIP is still billed by file duration (3 VND per second) until expiry. New separation needs are directed to tachnhac.com (newer AI, more tools, a free tier). The hand-processed deep-separation service (50,000–150,000đ, by contact) is unaffected.
