“Ptich It” is a small application that applies pitch shifting on single audio files, or audio folders.
Apply either a fixed pitch factor, or use the dynamic function to apply a time varying pitch shift.

Set a static pitch shift or use the function graph to set a varying pitch factor.
Use the “+” button to add points to the function in specific time positions and pitch.
Every point of the function can be fine-tuned at both the time position and the pitch factor after its creation
Preview the pitch shift in real-time the, for the loaded file or, iterate preview through a loaded folder.
The maximum pitch shift is limited between +3 octaves and -3 octaves. Any transposition is relative to the audio file’s actual pitch.

Store and recall the function graphs, low-value sensitivity and Max pitch shift value.
