AI MP3 to Text Converter

No. Files are read at whatever bitrate they were encoded at, from a low-rate voice recording to a high-rate music file. Lower bitrates carry less detail, which can cost accuracy on names and numbers, but the file does not have to be re-encoded before it is uploaded.

Each MP3 is submitted as its own job, and further files can be added while earlier ones finish. Submissions are rate-limited, so a large folder is processed in batches rather than all at once. Naming each file clearly before upload keeps the exported transcripts easy to match.

Long files are accepted up to the limit shown on the page, and an hour-long interview is comfortably inside it. Processing time grows with duration, and the daily free allowance is measured in audio time. Splitting a very long file by chapter makes the transcripts easier to reuse.

Time markers can be switched on when the transcript is produced. Each paragraph then begins with the position in the file where it was spoken, which is useful for a long archive where a passage has to be checked against the audio. Without them the text reads as continuous prose.

Silence is skipped and does not appear in the transcript. Music that carries no speech is usually left out as well, while a song under a spoken passage can produce a stray line. Those lines are easy to delete in the editor, and the rest of the transcript is unaffected.

Yes. A chapter recorded as MP3 is treated like any other spoken file, and the narration becomes text with paragraph breaks. The result is useful for searching a chapter, quoting a passage, or producing a reading companion, though it is not a replacement for the published text.

Every part of the text can be corrected, including names, numbers, and punctuation, and paragraphs can be split or merged. Corrections happen before export, so the downloaded file holds the corrected text rather than the raw first pass. A long transcript can also be copied out one section at a time.

A file can be converted and the text exported without payment, and no card is requested to start. The free allowance is measured in audio time per day rather than in files, so one long recording uses more of it than several short ones. The limit resets the following day.
