CUSTOM DIY PORTABLE BOOTH PLANS
The Booth plans you will receive has the following characteristics:
- 67 pages of instructions, no less than 335 documents, layouts, and photos.
- Exterior dimensions = 10′ 5 1/2″ X 8′ 1 1/2″ X 7′ 10 5/8″ (3187 mm X 2476 mm X 2404 mm)
- Interior dimensions = 9′ 5″ X 7′ 1″ X 6′ 9 1/2″ (2870 mm X 2159 mm X 2070 mm).
- The floating floor isolates down to at least 48 Hz and is effective against rumble and structure-borne noise
- The walls of this booth will have ‘at least’ STC-58. (much more if the room that this booth is in already has at least 30 dB isolation from the outside world)
Price: $100
TO ORDER:
When you order, please note in the comments “Portable Booth Plans” and your email address. I will send you a folder link on Dropbox for all the documents.
DIY Mixing/Mastering DESK Plans
The entire desk is an Air-Transparent Diffraction device with phase change which renders the desk accoustically near invisible. The Desk plans you will receive have the following characteristics:
- xx pages of instructions, no less than 335 documents, layouts, and photos.
- Dimensions = 10′ 5 1/2″ X 8′ 1 1/2″ X 7′ 10 5/8″ (3187 mm X 2476 mm X 2404 mm)
Price: $100
TO ORDER:
When you order, please note in the comments which desk (II or III), and your email address. I will send you a folder link on Dropbox for all the documents.

COMING SOON
“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.
A pdf version is not planned.
