Theory of Upsampled Digital Audio - MLSSA
http://www.mlssa.com/pdf/Upsampling-theory-rev-2.pdf
An upsampling digital filter still attenuates the ultrasonic images to a certain degree, the attenuation increasing with frequency. Upsampling is therefore a compromise between using a sharp anti-imaging filter and using none at all. An upsampling digital reconstruction filter purposely violates signal-processing theory. The reconstructed

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 ...

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.

To eliminate all the artifacts requires a very high order analog filter (many stages), which is going to itself create large phase artifacts in the audio bands. When you upsample audio, you don't interpolate between samples (or shouldn't), you insert 0's between samples. 20-30-40 would become 20-0-0-0-30-0-0-40-0-0-0 (for 4x oversampling).

Like audio cables' sonic quality and such are essentially nonsense claims (aside from the realm of IEM's for instance or gear with impedences that will cause a FR to shift heavily with odd cables that have like 9 ohms as some folks have spoke about).. But with upsampling, it doesn't make sense to me even from a marketing perspective.

This is done in an ADC (Analog to Digital Converter). 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 …

I changed the sample rate on my mac's Audio midi set up to 96 to play hirez files I recently bought. I noticed that the sound when playing ALAC files (16/44) changed significantly. Lower bass, lower volume. Seems this is not an upsampling problem but changing the sample rate certainly changes SQ on CD quality files. I'm using a Dragonfly v1.2 DAC.
