Thanks. Easy to follow but still very detailed. Great read.

If you have not done so already, check out Mr. Lavry's posts in this thread on RAP:

384kHz PCM ???

Also easy to follow and makes, IMO, perfect technical sense.

Interesting, although I don't really think it's more accessible to the "average" reader than any other sampling theory paper.

I'm not sure I agree with his conclusion that 192khz is *inferior* from a practical point of view, as once the 1-bit x-mhz data exits the decimator it's in the digital domain and can be represented more accurately with higher PCM rates.

I agree with the sentiment though. Properly noise-shaped 44/16 is more than enough for audio recording imho.

It's a very good paper - and presents an interesting way to show the validity of the Nyquist theorem without going too deeply into the frequency domain. Another good weapon to use against the "Nyquist was wrong" naysayers.

OT, but i thought it was funny after reading lavry's posts to see a google ad on this page for "gigasamples per second a/d cards"

LMAO @ google.
