Frequency shifting.

Does anybody know how to create the network that shifts the phase of a signal 90 degrees regardless of frequency in the audio range? (Hilbert transform?)

Reverse echo?

Is there any way to write to the SRAM and then read it backwards, adding feedback would give you a reverse echo.

Without the interpolation given by the CHO RDA command won't the sound quality suffer?

Triangle wave???

Is there anyway to generate a triangle wave, based on the analog model of a comparator followed by an integrator? You could also get a square wave if you sampled the comparator rather than the integrator.
