The Pitch Shifter Component takes an input signal and shifts the frequency of that signal to a specified distance, either up, down or both, from the input signal. The input signal is the dry output, and the shifted frequencies are the wet signal. You can use this to de-tune an instrument to produce a "thicker" sound similar to a chorus effect. In addition, you can take the input signal up / down a full octave to add a different "voice" to the output. The Pitch Shifter can be used on any kind of audio signal.

Master Bypass |
Bypasses all of the component's controls. |

|
Stereo Spread (%) |
Available when the I/O Configuration Property is set to Stereo In/Stereo Out. Determines the separation spread between the channels. 0% is equal amount of each channel mixed to the other, 100% is complete separation of the channels. |
Default = 100 0 - 100 |
|
Detection Frequency (Hz) |
This is the mid-point of the range of frequencies you want to be shifted. |
Default = 330 Range = 81.4 - 660 |
|
Left/Right Detected Pitch (Hz) |
Displays the frequency, or pitch, of the input signal. You can use this to assist in setting the Detection Frequency. When the I/O Configuration is set to Mono In, only one Detected Pitch field is available. |
Default = 1.00 kHz Range = |
|
Left/Right Pitch Shift (¢ cent) |
Sets the distance you want to shift the output wet signal from the input dry signal. When the input audio signal changes pitch, the output signal follows the changes directly. 1200 cents is an octave. When the I/O Configuration is set to Mono Out, only one Pitch Shift field is available. |
Default = 0 Range = -1300 - +1300 |
|
Crossfade Time (ms) |
In order to raise or lower the pitch of a signal, the Pitch Shifter speeds up the input, or slows it down. This means you end up with a shorter or longer set of samples than the actual input. The Pitch Shifter either duplicates a set of samples and plays it back again, or truncates the set of samples. The Crossfade Time adjusts the transition time between sets of samples. A shorter time gives you a more abrupt transition, a longer time produces a smoother transition. |
Default = 20.0 Range = 0.100 - 100.0 |
|
Left/Right Delay (ms) |
The Delay Time delays the wet signal from the dry signal. |
Default = 0 Range = 0.00 - 100 |
|
High-Pass Frequency (Hz / kHz) |
Frequencies below this frequency are attenuated. All frequencies above this frequency are amplified based on the setting of the Wet Gain control. |
Default = 20.0 Range = 20 - 20,000 |
|
Low-Pass Frequency (Hz / kHz) |
Frequencies above this frequency are attenuated. All frequencies below this frequency are amplified based on the setting of the Wet Gain control. |
Default = 20,000 Range = 20 - 20,000 |
|
Wet Solo |
When engaged, allows you to listen to the wet signal by itself. |
Normal / Solo |
|
Wet Gain (dB) |
Controls the gain of the wet output. |
Default = 0 Range = -60 - 10 |
|
Dry/Wet Mix (%) |
The percentage of wet to dry signal sent to the output. 0% is all dry signal, and no wet. 100% is all wet, and no dry. |
Default = 100.0 Range = 0 - 100 |
