The bit depth will have more of an effect than the frequency, but both together make a huge difference.  The difference between 8-bit and 16-bit at the same frequency for example is huge.  Of course on the CPC both those are much lower, probably 4-bit and 11KHz and some more knowledgeable person will be along with a more definite answer shortly :D

JavaCPC's Digiblaster uses 8bit unsigned.
The frequency depends on the used sample.
(I can't tell you the frequency range, Digiblaster can play)

Don´t underestimate low samplerates!
16-Bit with a samplerate less than 15 Khz sounds really odd. (let alone 8 Khz or 3 Khz...)

Yes, samples played via AY-3-8912...
But the Digiblaster offers 8-Bit-Quality, or not?
Is the Digiblaster capable to sound as good as the Amiga´s Paula?


EDIT: @Markus, du hast es bereits erwähnt, also 8-Bit.

@ Markus: That was quick, I only sent it yesterday. And yes... Oops I forgot to mention, that the one I sent you was one of the original prototypes. It protrudes 3mm further down than the final version, so it hits the desktop a little. You can file off about 1.5mm from the bottom (as far as the lowest PCB track), which might be just enough to avoid the clash with the table, if not, a carefully placed Amstrad Action under the CPC should be enough to put things right :D

The DigiBlaster is also 8-bit (unsigned), but the sample rate depends on the software being used, I've no idea what Digitracker or the other packages use though. It can easily handle very low frequencies, but the higher end of the frequency scale will depend on the maximum sample rate.
