Topic: oversampling for DSP?
There are quite a few rumors that while oversampling may not improve sound quality of the original audio, it may improve the result of DSP (such as corssfeed, bass/treble boost, or parametric EQ). this topic is also discussed in this forum: https://forum.rme-audio.de/viewtopic.ph … 04#p157104
I want to understand if such rumor is true --- That is, is there any benefits for me to oversample 48khz format by 4x to 192kHz, in order to get better result from the DSP algorithms the ADI-2 provides.
equivalent question: does upsampling help to lower the noise of a given IIR (in ADI-2, most dsp algorithms such as PEQ or Bauer are all implemented with IIR filters [Infinite impulse response])?
