> - Equalisation with a curve that starts at -6 db at 20Hz, peaks at 6 db at 150 Hz and then curves down to -30 db at 20000 Hz. this seems like a very bad idea, this will give you very dull, boomy sound, for most recording setups. It's a bit too much work to type out everything here, but this is not good advice. Most of the time the best improvements are to be made with getting a decent microphone and set it up properly (doesn't have to cost much more than $100).
