It may operate in one of the following modes:
- linear ramp across up/down frames to the new value
- logarithmic movement to new value
- limits the change in samples to be in the given range
The argument is the vector size for the operation. It defaults to 512, but should be set appropriately for the size of the vectors you feed into the vectral~ object.
Common Box Attributes
Multichannel Group Attributes
In middle inlet: A sync signal received in the middle inlet is used to synchronize the input index of the vector being processed. The sync signal will typically be in the range 0 to n-1 where n is the size of the vector. If the range of the sync signal is different than the output index, the incoming vector will be "bin-shifted" by the difference between the two signals.
In right inlet: Signal data to be filtered. This will usually be frequency-domain information such as the output of an fft~ or fftin~ object.
Multichannel Group Messages
A smoothed version of the signal input into the right inlet, according to the parameters given to the vectral~ object.
