Parametric EQ would be cool. Especially if you develop a good UI for it. I'm thinking maybe like a custom QWidget that lets you move the filter points directly in the frequency response graph. You'll probably want to use biquads for the filters. There's a good biquad implementation in basic_filters.h, it's used for the first 6 or so filters in the filter list. There is no peak/shelf filter implementation, but it's just a matter of passing different coeffs to the biquad. I've been thinking we should put the biquad implementation in its own class anyway, so this could be a good opportunity to do it. Then you could use the biquad class directly in your plugin and wouldn't have to rewrite it from scratch. ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
