Program. Sound editor

Good evening gentlemen. Do you know the attack :)
So the program for editing any audio. The program works, if I remember:
decomposes it 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, I write in the spirit of the blond. Dachshund, what else ...
I’ll remember I’ll write.
