“Recording Studios and Other Acoustic Spaces” by John H. Brandt & Ron Sauro
This book gives you an insight on the history of music recording studios and guides you step-by-step on how to successfully transform a room in your house into a beginner studio, without compromising on sound quality. We cover the all important mixing room, booths, isolation, and of course, acoustics. We also show you how to build your own traps, diffusors, studio doors and windows. Speakers, wiring, and ventilation are also covered in this all-in-one guide.
The subjects covered (so far) are listed in the Table Of Contents below. The book is due to be finished editing very soon and will be a Hard-Cover A3 size landscape book of about 500 pages. The book will sell for about $300 to $350 USD and contain coded access to online material.
