I received this book in a microphone bundle. First I had thought that it won`t be useful for me, but when I read the first few pages, I realized that I didn`t know that much about recording studio equipment, microphones and soundproofing... I read it trough and now I`m dreaming about building my own studio... It has a lot of helpful information about recording software, sound editing, the differences between dinamic and condenser microphones and much more... It lists what you need to start your own studio. It`s written in two languages: English and German, so it can be useful for learning a new language too.
