Transcribe WAV to text, free

Upload a WAV file and get the text with each speaker and the minute they speak. No account: the first 10 minutes of each file are transcribed, for files up to 200 MB.

Drop your audio or video here, or choose a file

MP3, M4A, WAV, OGG and OPUS (WhatsApp voice notes), MP4, MOV, WEBM… Up to 200 MB.

Free, no account needed: the first 10 minutes of each file, 3 a day. The file is deleted when it’s done and the result after 24 hours.

What a WAV is

WAV stores audio uncompressed, just as the microphone picks it up. That’s why it’s the format of professional recorders and editing programs, and also why it takes up so much space: at CD quality in stereo, around 10 MB a minute.

Where they usually come from

A WAV normally comes from audio equipment or software:

  • Handheld recorders, which usually let you choose between WAV and MP3.
  • USB microphones and recording programs such as Audacity.
  • Audio interfaces and mixing desks that record to a card or a computer.
  • Voicemail systems and phone systems that send messages as a WAV file.

If it’s over 200 MB

A long WAV quickly goes over the free tool’s limit. You have three options:

  • Trim the part you need: the free tool transcribes the first 10 minutes.
  • Export it as FLAC, which compresses without losing quality, or as MP3, which is enough for speech.
  • Create a free account: you upload whole files of up to 2 GB.

How to do it

  1. 1

    Upload the WAV

    Drag it into the tool on this page or choose it from your computer, up to 200 MB.

  2. 2

    Wait a moment

    Echo detects the language, writes down what’s said and separates each speaker.

  3. 3

    Copy or download the text

    With times and speakers or just the text, to paste anywhere or save as TXT.

Frequently asked questions

Is a WAV transcribed better than an MP3?

Hardly. For speech, a normal-quality MP3 or M4A gives the same result; the WAV is just bigger. What changes the text is how it was recorded.

Which recording settings should I use?

Mono is enough for speech: it takes half the space of stereo and is transcribed just as well. Put the microphone close to whoever’s speaking and avoid very echoey rooms.

Can I upload a 24-bit or 96 kHz WAV?

Yes. Echo converts the sound to what the model needs when transcribing, so a higher resolution doesn’t change the result: it only makes the file bigger.
