Does upsampling affect audio quality?
When we upsample a 44.1kHz 16-bit file to a higher rate and depth, like 96kHz 24 bits, we typically get better sound quality. And since the magic of upsampling just sort of works at the touch of a button, we seem to be getting more for nothing. After all, the file size is considerably bigger.
Does upsampling make a difference?
Major Contributor. Converting a digital (sampled) signal to a continuous analogue waveform requires interpolation to produce the values between sample points. Doing part of this interpolation digitally (upsampling) simplifies the analogue circuitry and gives better results. That's all there is to it.
Why is upsampling important?
The purpose of Upsampling is to manipulate a signal in order to artificially increase the sampling rate. This is done by... Upsampling is an effective way to reduce time between samples of a signal without resampling the original signal.
Does oversampling sound better?
Oversampling mitigates issues, including aliasing, and will usually yield smoother, more pleasant-sounding results at the cost of using more CPU power. But all oversampling algorithms aren't made equal, and some are better than others.
