I would like to find out if there is a way via a switch or otherwise to get more Bass.
why would you want to do that, adding bass before encoding will make it tougher for encoder to encode, I'm just speculating
Applying bass on playback is much easier.
But if you insist on applying it before encoding, You can use front-ends such as foobar2000, dbpoweramp, winamp to name a few
Just slide 60-100 Hz slider higher than others, you will get your "bass" then
Winamp's eq is an utter crap, dreadful, especially for PCM waves (before I get another TOS8, to be precise, the version I'm using is 5.03a, the mp3's equalizer is OK, but the EQ starts to fall apart when it is playing everything else besides mp3....really weird)
