Detailed Description

Downsample the input signal by dropping samples.

Downsample the signal by an integer factor N. The output of the DownSampler will only reproduce the input samples at multiples of N.

Note that the DownSampler does not take care of any low pass filtering to avoid frequency aliasing.

Note that the DownSampler restarts counting and dropping samples for every given slice. Consequently, if the number of input samples is not divisible by the downsample factor, the sampling will be not uniform around the slice borders.

Controls:

• mrs_natural/factor [w] : factor to downsample by.
