WaveWarp 2.0 Component
      
Multirate:
Simple Control DownSampler
|
Functional Description
Reduces the sample rate of the input control signal by an integer factor, M, by retaining only
every Mth sample. The output sample rate is a factor of M lower than the
input sample rate.
Separate components are provided for 2, 3, 4, and M (flexible) downsampling
factors.
IMPORTANT: This is the simplest form of downsampling and has no protection
against aliasing. It should not be used if the input control signal has spectral
content above Fs/2M, where Fs is the input sample rate.
However, for most control signals used in WaveWarp, this is rarely an issue,
so this component is adequate.
