Convert audio to SRT subtitles

Podcasts, interviews, voice memos: upload the audio and get a timed SRT back in about a minute, no video required.

Built for audio-only workflows

Not every project starts as video. Podcast episodes, recorded interviews, and voice-memo drafts are audio from the start, and captioning them usually means pairing the file with a static image or waveform later — but the transcript and timing need to exist first.

Supported audio formats

• MP3: the standard podcast export format.
• WAV: uncompressed recordings straight from a mic or recorder.
• M4A: common from voice memo apps and Apple recordings.

Steps

1. Upload the audio file directly — no extraction step, since there's no video track to strip.
2. Wait for transcription and forced alignment.
3. Choose fixed word count or natural sentence breaks for line length, and edit any lines that need it.
4. Export the SRT file.

Frequently asked questions

Do I need a video file to generate captions?

No. Upload audio directly — MP3, WAV, or M4A — and skip the video-to-audio extraction step entirely.

Can I translate a podcast transcript?

Yes. After transcribing, choose a target language and the tool translates each segment while keeping its original timing intact.

What can I do with the SRT once I have it?

Pair it with a static video or waveform export for platforms like YouTube and social, or use it as a searchable, timestamped transcript on its own.
