Shift a pitch by semitones and cents from a starting frequency.
Each semitone adds or subtracts one hundred cents, and the shifted frequency is the base times the ratio of cents over twelve hundred. Pitch shifting changes musical character, and knowing the exact ratio is essential for tuning, sampling and DJ key matching.
Pitch Shift
Freq = base x 2^(total cents / 1200); one semitone = 100 cents
