Parametric EQ

Oddly enough, or perhaps not strangely at all, that’s rather similar to one that I made (for the same reason) :slight_smile:

The plug-in was based on the channel Eq of a well know make of mixing desk.
I’m sure I had another version of this that also included a fixed gain “LF roll-off” as found on this particular desk, but I can’t find that at the moment.

One thing that might be worth mentioning is that, although not currently used, I think it is probably best to include the “categories” line in the plug-in header. (I’ve just added it here: https://forum.audacityteam.org/t/conventions-for-nyquist-plug-ins/16324/1 )

Also, your code says “;version 3”, but it is actually a “;version 1” plug-in.

Just as a matter of interest, was there any particular reason why you wrote the filter code as a function rather than just “in-line” code?
