+#### DC_REMOVE (default disabled)
 Remove DC of input signal by substracting average of input signal. This can be usefull if low frequencies are of intresst since the DC component normally distorts the spectrum near 0Hz.

 Sets the sample rate of the raw input data (from data source). The default value is the ecmc rate for that data source.
 Note: only a lower and "integer" division of sample rate can be defined.
