Hello,
I don't really know what I'm doing, but I'm having a lot of fun :-) I taped a couple of great shows recently on my new R-09. One of them has very boomy low end that I would like to reduce in post-processing. I have been experimenting with Audacity. My source files are 24/44.1 WAV. So far I have tried this:
Import to Audacity WAV > Select 30 sec portion > Normalize to 0db > HPF @ 100Hz > Amplify
Import to Audacity WAV > Select 30 sec portion > Normalize to 0db > Apply EQ curve > Amplify
I read that often the really boomy parts are somewhere within 100-180Hz. If I apply an HPF of 180Hz it seems like it will remove too much info, but 100Hz still leaves some boominess. So, I tried making my own EQ curve to keep some of the low-end and cut out a bit more above 100Hz (see screenshot of curve in the zip file linked below). But I don't know if the curve I made is appropriate.
I think both of these 30-sec clips sound better than the raw file, but I'm guessing I can improve upon them. So what tricks can I use to achieve even better results?
Included in the 2.9MB zip file: raw.mp3, eq1.mp3, hpf100.mp3, eq.png (mp3's are 256 kbit, exported from Audacity).
