Do CD's reproduce lower frequencies much better than higher freque 2008-12-30 07:14:43 The sample rate for compact disc digital audio is 44.1 kHz. This means that, due to the Shannon Sampling Theorem, CD's can effectively reproduce frequencies up to about 22 kHz, where each sample defines the sound wave's point twice per Hz. But is the sample rate for CD's the same for all frequencies, or is 44.1 kHz just its maximum - meaning does the sample rate for CD's vary depending on the frequency being sampled, or is it the same regardless? I ask this because if it is constant regardless of the frequency being sampled, than CD's would be able to reproduce lower frequencies much better than higher frequencies. For example, a 100 Hz sound wave would have 5 times as many samples per Hz as a 500 Hz sound wave, thereby providing more data to reproduce it more accurately. But is this what actually happens?
