This is interesting. I'm trying to figure out where we don't have random access. For example, a wavetable oscillator is a random-access situation, as is playing a soundfile. Maybe not the majority of the time but certainly in some cases.
What happens if you have a fixed delay and change the delay time? Is whatever happens "acceptable"?
Also interesting about this is that we could use an allpass building block inside of the implementation. Which I guess means we need to port this class from Jamoma1: https://github.com/jamoma/JamomaCore/blob/master/DSP/extensions/FilterLib/includes/TTAllpass1a.h
Actually @tap, you already ported it: https://github.com/jamoma/jamoma2/blob/master/include/objects/JamomaAllpass1.h
;)
The Jamoma::Allpass1
class could work in terms of creating a proof-of-concept. It would be much more efficient, however, to use a dedicated building-block with a fixed 1-sample delay.
In Jamoma1 that filter was called Allpass1a
instead of Allpass1
. There's got to be a better way of naming these though.

Detailed here. Foudn during research for issue #60.
