Recording a karaoke take
The karaoke recorder plays a backing track while capturing your microphone, then mixes the two into one file. Pair it with the vocal remover to build an instrumental from any song you own, and you can cover almost anything.
Latency matters when singing along: the tool aligns the captured take with the backing track so your vocal does not drift late against the beat. Monitoring with headphones is strongly recommended — speakers let the backing track leak into the mic and make the mix impossible to balance.
Reverb and delay on the vocal path make a dry bedroom take sit better against a produced backing track, and the vocal-to-music balance is adjustable before export.

- 01Load a backing track or instrumental.
- 02Put on headphones and allow microphone access.
- 03Record your take while the track plays.
