Synapse Audio Fat Space v1.0.0 READ NFO-R2R

quote by zikedMy guess is that oversampling alters the audio spectrum in ways the plugin cannot, and he likes the sound of it?

oversampling is just literally the process of extending the bandwith of the signal by sample rate conversion with the implementation of filtering techniques, no more, no less. at the very best the artifacts generated by oversampling should only be noticeable at the very high frequencies of the signal, including the inaudible ones by human hearing (around >16khz-20khz) and ultrasonics, and these "alterations" are typically linked with filter order, fir or iir usage, volume and phase changes. some ppl describes these artifacts as "smearing" of the frequencies, "delay" of the signal, "volume loss" at high frequencies, pre and/or post ringing of high frequencies, etc. I personally think that these artifacts are more noticeable in "brute force" oversampling such as in metaplugin, especially with cumulative usage.

now, according to an old comment made by fabien from tdr a while ago on this thread https://varietyofsound.wordpress.com/2012/11/02/working-itb-at-higher-sampling-rates/ , oversampling linear processes may actually add more problems than benefits

quoting fabien:
"It makes absolutely no reason to oversample linear processes (EQs, linear filters, delays, reverb, static gain). Oversampling can even reduce their performance! In the case of a simple IIR based filter, such as a peaking EQ, oversampling N times will actually increase precision problems N times (at least). That is, the filter will be half as “good” at the double rate. This becomes quickly audible at low frequencies. Generally, keep in mind that doubling the sample-rate also means halving the precision! Sadly, precision is the most important thing for all recursive filters (the basic component of almost anything audio)."

so, it seems that oversampling linear processors is actually bad, but what I'm still quite not understanding is if processing upsampled audio files (say for example, audio files upsampled from 44.1 to 96 khz) with linear processors also brings these problems that fabien mentioned, bc that to me seems like an indirect implication of his statement. anyways, I'm gonna go to the bottom of this on gearslutz and start a thread about this topic, hopefully fabien will chime in and clarify the topic.

glad to have saved u some time
