So, what's the verdict so far?

Is this ready for me to send to Mark for inclusion in Hijack as beta?

The main thing I need to know is that no previous functionality got broken and that the feature appears to work as advertised - which from the posts above, I take to be a yes. ( the bonus disable_bassboost_FM feature aside - if the jury's still out about that, then fine - that code is clean and simple and I can't see any reason why it shouldn't work and it is 'bonus' to the original feature request.)

So basically, that means that the boost/cut appears to work, and that changing volume/input or eq doesn't result in any new nasty noise artifacts...
