You need the rights to every recording you upload. You are responsible for the voices in it, and for what you do with the cleaned file.
Free cleaning covers files up to 60 seconds, 5 files an hour from the same network. The limit can change. A pass can fail, and a thin or odd result is not a file you have to use.
This pass turns down steady noise under speech. It does not fully remove a strong echo, separate two speakers, or lift a voice out of a song.
