Line 47:

An audio CD can represent frequencies up to 22.05 kHz, the [[Nyquist frequency]] of the 44.1 kHz sample rate.

The [[bit rate]] is 1,3781411.1252 [[Data_rate_units#kilobit_per_second|kb/s]]:

2 channels x 44,100 samples per second per channel × 16 bits per sample = 1,411,200 [[Bits per second|b/s]] = 13781,411.1252 kb/s.

As each sample is a [[Signedness|signed]] 16-bit [[two's complement]] [[Integer (computer science)|integer]], sample values range from -32768 to +32767.
