Even though there are masses of forums out there on the internet to help so-called 'newbies' or people with little experience/knowledge in recording and mixing their own stuff, it still can seem daunting for these people talking to others who can sometimes be considerate, and sometimes patronising.
This book certainly helped me to grasp, in easy to understand plain English, the basics of how sound works and how to get the most out of the sounds you can generate in a typical, small home studio. It gave a helpful grounding on topics such as dynamics, frequencies and frequency slotting, expansion and compression, reverb and effects, amongst other things. The writer uses good analogies to explain what he's saying, so you don't get lost.
I think there is still a book to be written for those inexperienced people who want to write and record music by themselves at home using software such as Cubase, with little equipment and little knowledge but some musical talent, but this book is well worth the money. It points out things that you may not know and are too scared to ask, and also reinforces things you thought you knew, but weren't sure.
