02 What Is It? You might have noticed your tracks sound a bit lighter and less in your face compared to the commercial ones you buy in a shop.
"In a nutshell what we're after is a disk you can listen to without having to get up to change the volume between tracks."

That's because these professional recordings have been processed to make them sound louder and bigger.
A mastering engineer will apply this sort of processing to make your track sound louder, fatter and more commanding.
A good mastering engineer improves your track sonically by using tools, for example, to control wayward high range and boost mid and low frequencies.
If you use a dedicated mastering house it can be an expensive process but it can help give your recordings a professional polish if you can afford it.
However, a lot of studios do have mastering capabilities and there are also loads of mastering plug-ins available for Mac and PC.
