hey, there is this phase rotation plugin called “disperser” which is using a cascade of allpass filters to change the phase of the input signal. It sounds really great on bass sounds.
@nathan was so kind to share with me an example of an Impulse going through a chain of 1-order allpass filters which already does the job (thanks a lot) and pointed out FOS.
Does somebody has experience with the FOS UGen and has an idea how the code could be rewritten with it for effiency reasons?
Secondly with the plugin you could set the “amount” which corresponds to the number of allpass filters and also a cutoff frequency which is missing here.
thanks
