Program. Sound editor

Good evening gentlemen. You know the attack :)
So the program for editing any audio. The program is valid if I remember:
decomposes into audio tracks, which can then be edited, and change the notes themselves.
I also remember that the notes there (in the video about this program) were red))
Damn, in the spirit of blondie writing. Tux, what else ...
I will write will remember.
