DSP Change Requests
Matt:
Coming next build:
Changed: Parameters in the Parametric Equalizer dialog show up to five digits of precision instead of two.

--- Quote from: mwillems on March 11, 2022, 12:06:56 pm ---So I was paddling around this morning, and it's not a huge deal, but I notice that the highpass and lowpass filter Q in DSP Studio seems to be rounding to two decimals. So for example, if I enter .7071 which is the correct Q for a 2nd order Butterworth, it rounds it off to .71 which isn't quite right. Any chance of more precision there?
Also it might be worth considering setting the default to something other than "1" as that's not an expected filter slope at any order so newly created filters will have unexpected behavior for naive users. To get back the old default behavior (where all filters are butterworth by default) it probably would make sense to set the default to whatever the appropriate Q is for a butterworth filter at that order (e.g. .7071 for 2nd order butterworth, 4th order butterworth has 1.307, etc.).
I put this here to continue the ongoing conversation, but let me know if I should post this in the build threads instead. Thanks again for all the cool improvements this cycle!

Aside, I was under the impression that Q is actually S in MC? https://wiki.jriver.com/index.php/Parametric_Equalizer#Q_or_S

So that's actually something that should have been fixed as part of this effort per Matt upthread. Feel free to test!

Could you expound on this a bit? A new Low-pass is set to 12 dB/octave and 1 for Q. Are you saying it should be 12 dB/octave and .7071?
You can change the slope, but that doesn't change the Q.
Thanks.
