A TwoWay.Signal stores values of the past and the future
 Constructors   Instances  



Take n values starting from time zero.
If you want clips from elsewhere,
call take after delay.





Take the value at time zero.



A signal that consists entirely of ones



shift signal in time,
keep all values but if required pad with zeros





shift signal in time,
zero values at either ends will be flushed



Delay by one sample.







General routine that supports delaying and prefetching
using a general onesample delaying routine.




flipPair :: (a, b) > (b, a)  Source 

for a Signal this means a reversion of the elements





Unmodulated nonrecursive filter



Modulated nonrecursive filter.
The number of values before time 0 (past) or
the filter mask lengths must be at most finite.



Interpolation allowing negative frequencies,
but requires storage of all past values.











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.
 Delay Int  Delay the signal by given amount of samples.
 Past [v]  Replace the past by the given one.
This must be present in each recursive filter cycle
to let the magic work!
