Where your MP3 usually comes from

MP3 is the format most podcasts, dictaphones and audio editors hand you by default. A few common places to grab one:

  • Podcast episodes. Most podcast websites have a Download link under each episode, and the file is an MP3. Hosts usually send guests the raw MP3 too.
  • Dictaphones and voice recorders. Plug the recorder into your computer by USB; it shows up like a memory stick. The recordings are in a folder such as VOICE or RECORD.
  • Audacity, GarageBand and other editors. Export the project as MP3. In Audacity: File → Export Audio → MP3. Mono at 64–128 kbps is plenty for speech and keeps the file small.
  • Call recordings. Many call recorder apps save or share MP3. Use the app's Share or Export option and save the file somewhere you can upload it from.

MP3 to text: common questions

How long an MP3 can I transcribe?

The limit is 200MB per file, so length depends on the bitrate. At 128 kbps that's about 3 hours; at 64 kbps (common for spoken-word podcasts) it's over 6. You can transcribe up to 5 files a day for free.

Does the MP3 bitrate affect accuracy?

Not much for speech. Anything from 64 kbps up sounds the same to the recognizer. What matters more is how close the microphone was, background noise, and people talking over each other.

Can I get the text with timestamps?

Yes. Every line of the transcript shows who spoke and when. You can copy it, download it as .txt, or download .srt and .vtt subtitle files when timing is available.

My MP3 is a podcast with two hosts. Will it tell them apart?

Yes. The transcript labels each voice (Speaker A, Speaker B…) so you can see who said what. Rename them in your own copy once you know who's who.

Is my MP3 kept after it's transcribed?

The file is uploaded to temporary storage and transcribed. We may then keep a private copy of the audio and transcript to improve Wave's speech recognition. It's never published. Don't upload recordings you don't want to share with us.
