Upsampling can also take place inside of DAW systems at various points. For instance, some plug-ins are based on processes that work better at higher sample rates . Part of the plug-in’s software code will include an upsampling process that occurs before the plug-in acts on the signal, and then downsample’s the audio to the sample rate of the session to re-inject …

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 …
Upsampling vs. Oversampling for Digital Audio - Audioholics
https://www.audioholics.com/audio-technologies/upsampling-vs-oversampling-for-digital-audio
Oversampling is performed at the ADC and then the signal is sent to the digital processing chain that does the filtering and any DSP operations. The upsampler (if any) sits somewhere between the DSP and filtering. Just like the …

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.

For its first CD players, Philips realized that by adding three zero-valued samples in between each valid audio sample, the effective sample rate would be increased to 176.4kHz, and the unwanted images, instead of lying 22.05kHz on either side of 44.1kHz and its multiples, would now lie at either side of 176.4kHz and its multiples. A more gentle, better-behaved, and more …

Oversampling gives you the same information multiple times more quickly. It can be treated like it was more different information but it’s the same information repeated. This allows the anti aliasing filter to be pushed far beyond the audible range where whatever amplitude FR distortion and phase FR distortion it creates are inaudible.

In essence, one is using the greater computational power of a computer to run more accurate/intensive upsampling whilst reducing the on chip noise created by that process in a DAC. There are many things in audio that might be considered woo woo. YMMV, but this is demonstrably real. One might prefer what their DAC does btw.
Does upsampling effect audio? | Steve Hoffman Music …

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.
Upsampling - Wikipedia
https://en.wikipedia.org/wiki/Upsampling
In digital signal processing, upsampling, expansion, and interpolation are terms associated with the process of resampling in a multi-rate digital signal processing system. Upsampling can be synonymous with expansion, or it can describe an entire process of expansion and filtering. When upsampling is performed on a sequence of samples of a signal or other continuous function, it …

Sort by: best. level 1. Ekalet. · 2 min. ago. Upsampling won't deteriorate sound quality and it won't gain anything in sound quality either. Not sure about the downsampling/sync question...perhaps someone can provide insight on that? 2.
