FFT
|
The FFT device is a spectrum analysis tool. It shows a representation of the output signal from the effect device immediately to its left. It is useful for tracking down causes of problematic frequency output that may be generated by some effect settings. Please note that FFT processing consumes substantial amounts of CPU power. Smoothing This control adjusts the amount of smoothing used to reduce jitter in the display. Increasing the Smoothing control results in a more stable display although accuracy may be compromised. |
Update Time
This control adjusts the frequency at which the audio signal is analysed and displayed. Shorter Update Time settings consume more CPU cycles (FFT analysis is a substantially CPU-hungry process).
TestTone
|
The TestTone device is a sine wave generator which can be used for checking the frequency and transient response of effects further down the signal path. The On Time and Off Time controls allow the device to cycle on and off for testing the responses of dynamics processors and other transient-sensitive effects. This device may also be used as an audio-rate FM modulation source for use with suitable devices such as the FilterMod effect. Pitch This control adjusts the frequency of the sine tone generated by the device between 7 Hz and 28 kHz. Amp This control adjusts the level of the test tone between -36 and +12 dB. |
On Time
This control sets the time for the test tone to be active if the Off Time control is set to a value greater than 0.
A continuous tone is generated with the On Time and Off Time controls set to 0. If the On Time control is set to 0 and the Off Time control is set to a value greater than 0, the device produces silence.
Off Time
This control sets the period of silence before the tone is produced again for the duration set by the On Time control.
TestPulse
|
The TestPulse device generates a pulse wave with a minimal PWM setting so that its value is 1 for a single sample with silence for the rest of the duty cycle. This creates even and odd harmonics, useful for checking the response of spectral effects such as filters further down the channel's signal path. Like the TestTone device, the pulse tone can cycle on and off for testing dynamics and other transient-sensitive devices and it can also be used as an audio-rate modulation source for suitable devices. Pitch This control adjusts the frequency of the pulse tone generated by the device between 0.1 Hz and 10 kHz. Amp This control adjusts the level of the test tone between -36 and +12 dB. |
On Time, Off Time
These controls behave identically to the On Time and Off Time controls in the TestTone device (see above).
