I'm using Sonar LE to record a station ID for a little online radio station experiment I'm trying to set up. I've learnt to use a compressor to increase the volume of individual tracks without peaking above 0 dB. I've also applied some compression on the master as suggested [here](http://avp.stackexchange.com/a/3304/1983). But the final mix still sounds awfully quiet compared to just about any music file I have on my computer.

Here are my tracks along with their peak volume, volume adjustment and applied effects:

My final mix compression settings are as follows:

What can I do to further pump the volume? I don't need it to be obnoxiously loud; I just don't want it to sound too quiet compared to the music on the playlist like it currently does.
