BaruVocal remover: split any song or video into vocals and a karaoke instrumental, with an AI model running in your browser.

BaruTranslate many subtitle files at once and download them as one ZIP.
Versi 0.9.0
PerbaikanSubtitle translation works on whole sentences, then splits them back over the original lines: far fewer broken or garbled fragments.
BaruAuto-sync can now match the spoken words to the subtitle text: accurate even with music, explosions or cut scenes (subtitles in the spoken language).
BaruDual subtitles: combine two languages into one file, as two lines per subtitle or top and bottom (.ass).
BaruWorks offline: pages and tools you have opened keep working without a connection.

DiperbaikiExported videos (dubbing, noise removal) no longer have audio 44 ms behind the picture.

Versi 0.8.0
