What MP3 actually is

An SRT is a plain-text subtitle file: numbered cues, each with a start and end timecode and the caption text. MP3 carries no timing of its own, so Typist transcribes the audio with word-level timing and builds the cues, turning a podcast or voice recording into subtitles you can pair with video or use as captions.

MP3 is a lossy audio codec, but at a normal speech bitrate it is perfectly clear for transcription, because voice sits inside the band MP3 keeps. The SRT quality depends on the recording, not the bitrate. Typist sets cue boundaries from word-level timing and groups the words into short readable lines.

Where these files come from

Podcast episodes, recorded interviews, voice memos, and audiograms, anywhere an MP3 holds speech you want timed captions for.

Readable on screen

Typist re-segments long speech into short timed lines of about 42 characters, at most two lines per cue, so the captions read cleanly. A whole spoken paragraph never lands in one subtitle.
