Some simple low & high pass filters with curve up to 96db would be very welcome !
I thing by puting 8 low & high pass filters of 12db in serial, I would obtain a 96 db one but all them in one device would be much more convenient !
I could do it in SDK .... But I don't know how to transform that in a Scope device ....
Finally, I made a modular one, up to 120db ! Stereo.
I had to add 12db on each filter output to keep the audio signal at the same level. (Modular filters output are -12db)
