- I read the above message in alt.guitar, but my email directed
- to `grey@bnr.ca' bounced, because the user `grey' is unknown at
- `bnr.ca'. So I post this question initially directed to Grey here,
- and encourage other people to react also.
-
- Some weeks ago I built a simple 8-bit AD/DA board to be used in a standard
- PC. It is possible to sample (with the AD) and play back (with the DA) at
- frequencies up to 400 kHz. With my 386 I am able to implement a real-time
- digital reverb and echo in Turbo Pascal, while still sampling at over
- 40 kHz or so. Now I would like to implement (just for fun) some of the
- fancier effects.
-
- I wondered whether readers have DSP algorithms (or pointers to them) to get
- well-known guitar effects, like flanging, phasing, chorus or distortion.

- Thanks in advance, Jos Groot
