I have question about the sampling rates of SACD and CD. The CD is said to have a "16 bit/44.1 KHz" sampling rate. My question is whether that is 16 bits/44.1 KHz PER channel OR does each channel have a 8 (16?) bit/22.05 KHz sampling rate and combined it is 16 bit/44.1 KHz.


The question goes out for SACD too......is SACD 2.8 MHz per channel or 1.4 MHz per channel?


Thank you! Sorry if I sound like an idiot...

I believe each channel has its own 16-bit, 44.1-kHz signal. A 22.05-kHz sampling rate would allow only a maximum pitch of 11.025 kHz before the low-pass filter, which would leave out part of the last audible octave.

Yeah, it's 16 bit per channel! The sampling rate is clear anyway.

16 bit x 44,100 Hz = 705,600 bit : 8 = 88,200 Byte : 1024 = 86.1 kB per second.

But 1 second of a Wave file weighs 172.2 kB.

i tot there are 2 channels... it's suppose like
16 X 2 X 44.1Khz....

[EDIT]: ok, i c ur point by comparing with file size... was reading too fast...
