How can I increase the loudness of the CDs burned on the internal CD-RW drive?
You can use a free software audio editing and recording program called Audacity. Using this program load your stereo track(s) into Audacity, then look in the effects menu and select normalize. Make sure to set highest loudness level to 0 db, which is the maximum digital volume level. You can hear the difference in volume when you use the test button. If you can't still get enough over all volume level with the normalize feature then you will need to compress and limit the stereo track, but I don't suggest getting your over all loudness levels that high because it ruins and lowers the dynamics of your music. Another words when you compress and boost the over all loudness of your album then all your music is at the same highest audio level which is very ear fatiguing. It may sound better to you at first at louder volume levels but you will quickly learn to hate it over time because it does not sound natural. That is why most music today is all about loudness and ear fatigue. And because of the loudness wars going on today every Record company is trying to have the loudest album out there thinking it will sell more copies. It is all false baloney, it really should be about the quality and dynamics of your sound instead of how loud it is.
