SV: Re: [sdiy] BBD clock circuit

[Seb Francis]

I have to say that using a digital delay with analog 
distortion/EQ/filtering/whatever in the feedback path gets pretty near 
to this.  I wasn't sure the pitch shifting delay modulation thing could 
be done well in digital - all the digital delays I've used in the past 
have been very glitchy when changing delay times.  But having just 
finished building one and writing the software I can truly say it is 
possible and it does sound very good.  And it has 20kHz bandwidth and 
96dB signal to noise ratio when you want it :)

Audio samples coming online very soon ...
