Audio to SRT Converter

Turn song vocals into .srt subtitles for video editors and platforms.

Free to use. Works with MP3 uploads, AI-generated tracks, and supported song links.

What this does

SRT is the universal subtitle format used by YouTube, video editors, and social platforms. Karaoke.io listens to your track, transcribes the lyrics, and writes them as numbered, timecoded SRT cues — so your music video, lyric video, or performance upload gets accurate captions without typing a single timestamp.

How it works

1Upload an MP3 or paste a supported song link — or generate an original song right here with AI.

2Whisper speech recognition transcribes the vocal and times every line and word against the actual audio.

3Preview the sync in the karaoke player, then download your file — plus every other format from the same result.

FAQ

Which editors accept the SRT file?

Any standard editor or platform: YouTube captions, Premiere Pro, DaVinci Resolve, Final Cut, CapCut, and most social platforms that accept .srt uploads.

Does it caption instrumental sections?

Instrumental gaps are left clean — cues only appear where vocals are detected, so captions never drift over solos.

Can I get VTT instead?

Yes — the VTT generator on Karaoke.io produces WebVTT from the same timing engine.
