Roj: ahhhhhhhhhhh... I see what you mean now
No, my macro program won't be able to do anything like that. What needs to be done is for Ian to program in context menu support, which, because it's OLE, is not fun to do in C++ (at least in VB you don't have to do AddRef, Release, QueryInterface and mess around with tons of pointers).
Picky: I see what you mean as well
You want two things: what's basically a "bass boost" button, and the ability to flip the plus/minus sign on the values for one channel of an MP3 (e.g. if it's a sine wave, you could get one channel as "sin(x)" and one as "-sin(x)", and you want to flip the sign on the "-sin(x)" to make it "sin(x)").
Oh, and I got your e-mail. Images have been uploaded and links will appear in a couple of minutes.
