MP3 is what a podcast host hands you and what most recorders save by default. Upload one and download cues timed to the speech, ready for the clip video you are cutting or the player on your own site. Files over 500 MB carry on at the upload page, up to 10 hours or 5 GB. The first transcript costs nothing, at any length · preview instantly without signing up · 1,000 minutes for $8, and credits never lapse.
How it works
An SRT holds nothing but numbered lines and timecodes, so the source can be sound alone.
Straight from a recorder, a host’s download button or your Downloads folder. Up to 500 MB goes in the box above; a longer show carries on at the upload page.
Words come back each carrying its own timestamp, usually a few minutes for an hour of tape. No signup to see the preview.
One click for SRT, or VTT for a browser player. TXT, DOCX, JSON and Markdown come out of the same job at no extra charge.
MP3 specifics
A spoken-word MP3 at a typical podcast bitrate lands near a megabyte per minute, so a ten-hour recording is roughly 600 MB — nowhere near the 5 GB ceiling. In practice the only limit an MP3 meets is the 10-hour one, plus the 3-hour cap before you hold credits.
Three jobs, mostly. It burns onto the still-image video people build around an audio clip; it rides beside a web player as a VTT track; and it lands in an editor as timed text when the sound is cut against footage.
Cue times count from the first frame of what you upload, so trim the 40-second moment first and its cues begin at 00:00:00. Nearby: audio to SRT for any sound file, video to SRT when there is a picture, YouTube to SRT for a public link, the caption generator for anything else, and transcribe an MP3 for words without cues.
Where the file goes
Most feeds play silently until someone taps. Cues over a waveform let the clip land before the sound starts.
Export VTT, point the player at it, and the episode page carries readable words that search engines and screen readers can both reach.
Premiere Pro and DaVinci Resolve import an SRT as a caption track, so the timing is done before you arrange footage.
The same job exports TXT, DOCX and Markdown, and the transcript stays in your searchable library.

No. An SRT is a plain text file of numbered lines with a start and end time on each, so audio alone is enough to build one.
