Memos, calls, and lectures
Each kind of speech recording goes wrong its own way. A voice memo has the phone close, but the room's echo and noise around it. Phone lines carry only a narrow slice of the voice, roughly 300 to 3,400 Hz, so calls sound thin. A lecture recorded from the back of the room is distant and echoey, and meetings bring laptop mics, fans, and keyboards.
The cleaner gives each voice a fuller, closer sound and removes what's around it. You get your file back in the format you put in, ready for Transcribe to turn into text, or for Remove silence to shorten the long pauses. Files can run up to 10 hours, long enough for a full lecture or meeting.
Questions
Can it fix a phone call recording?
Yes. It restores a fuller voice from the thin, muffled sound of a phone line, and clears the line's noise.
Is it free?
Yes, for the first minute of each file, 3 times a day, with no sign-up. For longer files, see pricing.
Does it work on iPhone voice memos?
Yes. Voice memos are M4A files, and you get an M4A back.
Does it work on Zoom recordings?
Yes. Zoom saves an audio-only .m4a next to its video recording. Add either one.
Which languages does it work in?
All of them. It listens to the voice's sound, not its words.
Can it clean a lecture recording?
Yes. It brings a distant, echoey speaker closer and clears the room's noise, which makes a lecture easier to follow and to transcribe.
Does it work with more than one speaker?
Yes. Every voice in the recording is cleaned, from a two-person call to a whole meeting.
