Pitch Transpose -
- Semi-Tones Transposes pitch in semi-tone increments, which equal musical half-notes (for example, the note C# is one semi-tone higher than C). A setting of 0 reflects the original pitch; +12 semi-tones is an octave higher; -12 semi-tones is an octave lower.
- Cents A fine control that adjusts pitch in fractions of semi-tones. Possible values range from -100 (one semi-tone lower) to +100 (one semi-tone higher).
- Ratio Determines the relationship between shifted and original frequency. Possible values range from 0.5 (an octave lower) to 2.0 (an octave higher).
Precision - Determines sound quality, with the High setting taking longest to process but the most recommended for professional applications.
Pitch Settings -
- Splicing Frequency Determines the size of each chunk of audio data. (The Pitch Shifter effect divides audio into very small chunks for processing.) The higher the value, the more precise the placement of stretched audio over time. However, artifacts become more noticeable as values go up. At higher Precision settings, a lower Splicing Frequency may add stutter or echo. If the frequency is too high, sound becomes tinny and voices have a tunnel-like quality.
- Overlapping Determines how much each chunk of audio data overlaps with the previous and next ones. If stretching produces a 'doubled' effect, lower the Overlapping percentage. If doing so produces a choppy sound, adjust the percentage to strike a balance between choppiness and chorusing. Values range from 0 to 50%.
- Use Appropriate Default Settings Applies a general value to Splicing Frequency and Overlapping.
