How Can We Fix It?Īll right, so we know when we move from 24-bit to 16-bit resolution we are now trying to get the same sound wave with less 'points on the graph' to represent it. Where the sound was at points B and C is no longer concrete, the computer plots a trajectory between A and D and the stuff that used to exist at points B and C is now approximated. We used to be able to represent a waveform with points A, B, C and D, but now we just have points A and D. This reduction, or 'shift' of audio data is referred to as quantization. You have less points to graph the same amount of data, so you can imagine that your nice smooth waveform becomes more angular in nature. This is a simplified illustration of the same thing that happens when you move from 24-bit audio to 16-bit audio. The result is a shape which resembles a curve, but has a lot more angular points to it. Trying to get the same data as the original waveform is impossible with 10 less points, so I have to settle for 'as good as I can get'. This results in a much more 'blocky' appearance. I've only allowed myself 8 points to 'graph' the waveform.
