Extract clean audio from any MP4.
Pull the soundtrack out of meetings, lectures, interviews and podcasts. Then push the result straight into TranscriptAI for a transcript and summary.
Why pull the MP3 out of an MP4
When you only care about the sound — a recorded lecture, a Zoom call, an interview, a podcast episode — the video is just dead weight. An MP3 is a fraction of the size, plays on anything, and is the format transcription tools, podcast hosts and audio editors expect.
What about quality?
MP4 files typically store their audio as AAC, so the track is re-encoded to MP3 at a high bitrate — for speech that's indistinguishable from the source, and for music it stays clean. You get a single, portable audio file with none of the video overhead.
Then turn it into text
Audio is only half the value. Once you have the MP3, one click hands it to TranscriptAI for a full transcript, summary, chapters and action items — ideal for meeting notes and study material.

Extracting MP3 from MP4
This pulls the audio track out of your MP4 and encodes it as MP3; the video is discarded. Audio quality is capped by what the original file contained.
