> I have heard it referred to as quantization. That is the continuous strea= m to analog audio is quantized into small "words" of length of 16 or 24 bit= s at the sampling frequency. Yes, and the accuracy of that process is everything. Once it's digitized th= e errors of digitization are permanent. Fortunately even cheap A/D converte= rs nowadays are very good. Nothing to do with data compression. Losses in the process? Way below imper= ceptible. -Dan |
