But wouldn't that introduce a significant DC offset ? ;-)

96dB = 20*log(2^16)

No, but the first 149 bits are zero. ;-)

Just a typo. 165 should be 16. Probably slipped off the 6 and hit the 5.

"As a reference, compact discs (CDs) have a dynamic range of 96 dB
using 16-bit Pulse Code Modulation (PCM), and a resolution of 165 bits
per audio sample operating at a sampling rate of 44.1 kHz. This is
705,600 bits of data per second per channel. The CD can store up to 74
minutes of two channel music on a single disc."
What equation do I use gets the number of bits per sample?
How did that website get 165 bits per audio sample?
Isn't CD audio 16 bits/sample?
44100 [16] = 705600
CD is stereo, so 705600 [2] = 1411200
2^16 = 65536 different levels of loudness
16-bit = 16[6] = 96 dB dynamic range
I am still confused about the 165 bit per audio sample. Is it a typo?
