What's happening is that certain frequencies are getting lost while others are being accentuated. The pitch of the bass notes has not been changed, which is what you're claiming it's doing.

OK, just trying to describe what it sounds like to me. So basically what it boils down to is that the bass has been lost for whatever reason and I need to EQ down the lower frequency mids which will hopefully remove enough of the muddiness so that you can at least clearly hear the singer and then I need to compress the result to make it sound louder.

So my next question would be on compression. The app I am using has a compression filter that looks like this...



I am at least quasy familiar with an EQ, but I don't really know anything about compression. Can somebody explain what all those parameters do and what I might want to tweak for this recording?

Thanks for your help,
