I am sure has already been requested but -
I would like the option for the simplistic "Tape Mode" algorithm in the Slip Stretch and Audio Transpose functions whereby time and pitch remain interrelated - when you shorten a clip the pitch goes up and vice versa. ("Tape Mode" is the algorithm used in Loop Construction View and, AFAIK, that's the ONLY place it's used).
The default stretching algorithm in CbB preserves pitch with stretching - which is usually preferred for music - but also creates artifacts as this is an unnatural thing to do. "Tape mode" simply speeds up or slows down the clip - like a tape recorder - and produces nearly zero artifacts (with the exception of vocal formants, "Mickey Mouse"). Tape Mode is far more transparent than "preserve pitch" when used on percussion and most instrument tracks.
This is a simple option request for the pitch and time tools NOT to be confused with "varispeed" that some are requesting to control an entire project playback rate.
