Possibly a nonsense theory due to gaps in my knowledge, but how different would the S2400 sound if the analogue filters were bypassed completely?
The reason I ask is that I recently created a very basic audio app using Python that has three buttons to choose 44.1/22.050/11.025kHz sample rates.
When you downsample from 44.1 to 22.050kHz, the aliasing is lovely. It produces this lovely juicy/crispy effect on the highs which I get occasionally with the S2400, but not always. I suppose it is largely dependent on the amount and type of high frequency content present in a given sample.
Is this because there are no filters in my app? Do the S2400 filters remove any additional aliasing from resampling / re-pitching, even if no cutoff is applied?
I’m pretty sure you can’t disable them completely? Just can only choose whether 1+2 are dynamic or if 3/4/5/6 are fixed in the Effects settings menu. You can’t bypass them completely so that the top/cutoff and bottom/resonance knobs have no effect whatsoever - or am I missing something?
there are the 2+4 analog filters that are the same as on the OG SP1200, as said you can bypass them.
then there are the per track digital filters that are controlled by the double pots, these are done in SW and they are e.g. bypassed if you set them to lowpass with the freq at max and the resonance at 0
what cannot be bypassed are the antialiasing filters in the DAC itself, but you don’t need to since they are made for 48kHz and will let through all of the 26kHz Lofi crunch
Ok, thanks. I should have specified all filters rather than just the analogue filters.
Going back to my original question, are the digital filters completely bypassed when applying no cutoff? That may sound stupid but I’m assuming their presence alone is affecting the sound, even if cutoff is not being applied by the top knob?
For example, would there be no change in sound if they were removed/disabled completely in software? That’s why I’m thinking I get this unique raw sounding aliasing in the app I made.
