upsampling Peaking Filters

Postby regressor18 » Mon Aug 31, 2020 10:37 pm

I am stumped.

Is there a way to upample a filter so when working on a 44.1 sample rate you can successfully have a peak filter at a higher center frequency higher then cutoff?

For example when working at 44.1, have a peaking filter with a center frequency at 24KHz, that is upsampled then downsample and plotted at sample rate. At 44.1, 24KHz will be over the cutoff (1) and will not work.

I havent been able to figure out a way to do this in Flowstone.

Dunno if you can do this well ... though, MIM method works in this well even without up-/down sampling.
