Yes. A free account cleans 1 hour of audio a month, in files up to 30 minutes. Without an account you can clean the first 30 seconds of any file to hear the result.
You decide. Up to 50% strength your own voice is kept and only the noise is turned down. Above 50% the voice is rebuilt for a studio sound. If it starts to sound robotic, pull the slider back.
Only in a simple way: there is an option to even out loudness to -16 LUFS. Shhh does not level separate speakers or handle multitrack sessions. For that, Auphonic is the better tool.
Yes, on every plan. Drop an MP4 or MOV. Your browser takes the audio out, Shhh cleans it, and the clean audio is put back into the same video. The picture is copied as it is, never re-encoded.
They are used only to process them for you, never to train models, and they are deleted after 7 days.
