Description of a basic filter that can be used in larger networks. Constructors Mask [a] A static filter described by its mask ModMask (Signal [a]) A modulated filter described by a list of masks FracDelay (T t v) t Delay the signal by a fractional amount of samples. This is achieved by interpolation. ModFracDelay (T t v) (Signal t) Delay with varying delay times. The delay times sequence must monotonically decrease. (This includes constant parts!) Delay [v] Delay the signal by prepending another one Instances Filter [] T
