New: dub audio files too

TutDub started with screencasts, and video is still our home turf. But a lot of the tutorials you make never touch video at all — podcast episodes, lecture recordings, voiceovers, audio lessons. So starting today, you can upload those too.

What changed

The upload screen now accepts audio files right alongside video: MP3, WAV, M4A, AAC, OGG and FLAC. Everything else stays the same.

If you upload an audio file, the result is also audio — a cleanly dubbed MP3 in your chosen language, spoken in your voice. No video processing, no silent screens.

What you get

The full pipeline runs exactly as it does on video:

• Speech is transcribed and cleaned — filler words like "um" and "uh" are removed.
• Your voice is cloned from the recording itself.
• The transcript is translated and re-synthesized in your voice.
• Mic noise and background hiss are reduced automatically.
• The finished MP3 is ready to download.

A new option: adapt timing to background music

Audio uploads get a toggle the video flow doesn't need. Turn on "Adapt timing to background music" and the music is kept — separated from the voice, with the translated speech mixed back on top, so an intro track or a music bed survives the dub — and we stretch phrases so they land in time with it. Leave it off and each phrase keeps its natural speed.

Same pricing, same privacy

Audio costs the same as video: 1 credit = 1 minute of audio. Files stay available for download for 96 hours after processing, and the voice-cloning policy is unchanged — no persistent voice model is ever stored.

FAQ

1. Which audio formats are supported?

   MP3, WAV, M4A, AAC, OGG and FLAC. If you have something else, convert it first and it'll be fine.

2. What if I upload an audio file? Do I get a video out?

   No — you get a dubbed MP3. Audio in, audio out.

3. Does the video timeline option apply to audio?

   No. Video timeline adaptation only makes sense for video. Audio uploads get "Adapt timing to background music" instead, which keeps the music and aligns phrases to it.

4. Is background music preserved in audio dubs?

   Only if you turn on "Adapt timing to background music". The music is then separated from the voice and the translated speech is mixed over it. Leave the toggle off and phrases keep their natural speed.

5. How much does dubbing an audio file cost?

   The same as video — 1 credit per minute of audio.

6. Does the 96-hour limit apply to audio files too?

   Yes. Output files are available for 96 hours after processing, then removed permanently.

7. Is the voice cloned from my audio recording?

   Yes, and it's deleted after the job is done — we never keep a reusable voice model or voiceprint.
