Regarding reverbs, one classic element is the Schroeder allpass: https://ccrma.stanford.edu/~jos/pasp/Schroeder_Allpass_Sections.html You can use it to smear a signal without any constructive or destructive interference. Generally speaking this lack of "color" is a disadvantage, but for your application it's probably very desirable.
Another observation: It works well on simple signals > but on something not perfectly periodic like a guitar chord it always > has the rhythmic noise of a poor loop. It's generally easier to recognize artifacts when they repeat at regular intervals. If you're taking the granular approach, I suggest randomizing as much as possible. If you want to avoid interference between the grains, try to synchronize them based on a cross-correlation <https://en.wikipedia.org/wiki/Cross-correlation>. – Evan Balster creator of imitone <http://imitone.com> On Fri, Sep 16, 2016 at 12:30 PM, Spencer Jackson <ssjackso...@gmail.com> wrote: > On Fri, Sep 16, 2016 at 11:24 AM, gm <g...@voxangelica.net> wrote: > > Did you consider a reverb or an FFT time stretch algorithm? > > > > I haven't looked into an FFT algorithm.
