WAV is uncompressed audio: it sounds great but takes up about 10 MB per minute. As an MP3 at 128 kbps, the same minute is about 1 MB, ready to email or upload.
Your file never leaves your device: it's converted right in your browser. Free, no account needed.
“Transcribe to text” opens TraScrivo with the file already loaded: free for files up to 30 minutes, even without an account. To transcribe, the audio is processed online and then deleted.
Digital recorders and many recording programs, including those used with USB microphones, save in WAV. To archive, send or upload an interview or a lecture, MP3 is far more practical.
Keep the original WAV if you still need to edit or clean up the audio: every conversion to MP3 throws away some information.
On a computer you can convert WAV files up to 2 GB, which is more than 3 hours of stereo recording. iPhone and iPad have less memory. Our guide to digital recorders and WAV files explains how to transcribe these recordings.
