However, the results might be interesting with 4-bit samples (It's quite useless for 8-bit samples). If memory serves me right, the -official- way of dithering is adding a noise signal to the original, do a plain shift on the result (making it 4-bit) and subtracting the noise signal afterwards. Someone in my department has been working on something like that. I heared the results a year ago, and it really did sound quite impressive. -- Martijn van Buul - Pino@dohd.cx - http://www.stack.nl/~martijnb/ Visit OuterSpace: mud.stack.nl 3333 finger email@example.com for my public key block - This message was sent through the cbm-hackers mailing list.
