Upsampling is important in audio editing process particularly in audio mixing and mastering. The primary reason is that digital effects (used by the software plug-in or built-in with your recording software) introduced some kind of unwanted artifacts or …

It is important to remember three things about all of these products: 1) other than making active the lowest 8 bits of a 24-bit word, no new audio information is created by any of these products; 2) as susceptibility to word-clock jitter increases with sampling frequency, it is always possible that upsampling audio data can make things worse, not better; and 3) no …

Upsampling: Take a digital stream that is at one sample-rate and bit-depth and create more slices (higher sample-rate) at a finer bit resolution (more bits = greater bit-depth). This can happen anywhere a designer sees fit to do it. A DAC will automatically adjust to an incoming digital sample-rate/bit-depth up to its internal capability.

Upsampling is on the other hand a rate conversion from one rate to another arbitrary rate. Oversampling in the ADC has been around for quite a bit of time, while upsampling of audio that results in a simple rate conversion is relatively newer. The figure below shows an example of oversampling.

In the majority of cases 2x, 4x let alone 40x upsampling will bring no audible benefits. Only in some specific cases it might. 4x or 40x fill not change or increase anything but the price. You would also need to understand that upsampling requires steep digital filtering which also ring around 20-22kHz even when upsampling say 40x.

audio coding”) are based on critically sampled filter banks, for obvious reasons. •Important Point: We normally do not require critical sampling for audio analysis, effects, and music 19 applications. We normally only need it when compression is a requirement. Two-Channel Critically Sampled Filter Banks 2) After upsampling, the signals ...
