Check entrances, breaks, key changes, backing vocals, and the final ending before rehearsal.
If you have the file, you can make the karaoke version.
AI separation keeps the instruments rich instead of thin and phasey.
Upload from a browser, follow the processing stages, and preview the backing track when it is ready.
Files expire 24 hours after job creation and are then removed by automated cleanup; nothing is shared.
Alignment, final playback level, venue context, and performance rights all matter.
A karaoke track should retain intros, count-ins, breaks, key changes, and endings so the singer knows where to enter. Because the stems share the source start time, the instrumental can remain aligned with existing lyric timing. Verify the first entrance and any rubato section before using it at an event.
Backing vocals may be grouped with the lead vocal and disappear from the instrumental. For some songs that is desirable; for others a chorus depends on response lines or a choir texture. The opening preview is only an initial check; review the complete unlocked output before relying on it for rehearsal or performance.
Making a backing track does not replace public-performance, synchronization, mechanical, or master-use permissions. Rules differ by venue and country. Use recordings you are allowed to process, and confirm the licenses required for public events, streams, monetized videos, or distributed karaoke files.
Do not normalize each source stem independently. Sum the selected backing stems first, compare them with the original mix, and then set the final rehearsal or venue level. Check the opening cue, first chorus, bridge, and ending so the singer receives the same arrangement landmarks throughout the song.
Export a short reference with the original vocal at low level or keep the licensed original available separately for cue recovery. This is useful when an entrance is ambiguous, a backing vocal disappears, or the arrangement contains a rubato break. The performance version can remain instrumental while the reference helps the singer and operator recover quickly.

Not always. Results depend on the recording, and reverb, doubled vocals, or overlapping instruments can remain audible.
The current model treats all vocals as one stem, so backing vocals are removed along with the lead.
