Every acoustic situation is different and "One Size Fits All" does not apply. Advice from well-meaning friends, associates, and online forums can not give you the answers you need.

Sound isolation solutions are often not simple. Acoustic isolation, particularly music, requires construction and is expensive. The same goes for balanced acoustics in a control room environment, critical listening/mastering room, and home theater. "If one thing is certain about acoustics, it is that if anything seems obvious it is probably wrong." - James Moir.

Acoustics is counter-intuitive and it can take years of trial and error for the hobbyist to obtain a suitable result, not to mention that the trial & error approach can be prohibitively expensive.

Get my help with your studio design today.

Contact me via email to receive a quote for the complete design/details for construction, isolation, acoustics, with drawings (AutoCAD 3-D with professional layouts), specific advice and continuous support during the building process and guaranteed results.

When you choose my services, I will become your personal consultant for your studio construction. I will be available to you during business hours here in Jakarta, Indonesia. You will receive recommendations on everything that you will need including materials and alternatives, construction techniques, and specific custom details unique to your situation. - You will also receive a Free copy of my book, "Build Your Own Home Studio".

All designs are drawn in AutoCAD 3D (.dwg), electronics in OrCAD, and can be converted for import to other programs. I send layouts in pdf and jpeg for printing and viewing on paper. I recommend that you get a copy of AutoDesk DWG TrueView available for free, OR download DraftSight (which you can draw with and edit/annotate my dwg files). I can import Google Sketchup files but do not use Sketchup for drawings.


1. Direction: The utilization of the space, sound transmission loss requirements, type of recordings, and the details of your current construction. You will be asked to send as many photos as you can manage. I like to say, "The devil is in the details"- it is. My service is specific and exact. Once we arrive at a specification for your studio, and my instructions are followed, I guarantee that you will obtain the balanced acoustics desired and the level of isolation specified or better.

2. Construction consultation: I will design the partition walls with details and specify specialty products & materials and the construction technique. I will need photos of the on-going work as it is being built on a daily basis - just as though I were an on-site consultant/contractor. Construction consultation will be on-going until completion of the project.

3. Acoustics: Acoustics design is viewed by some as a subjective issue. It is not. The 'look' of the acoustics is, of course, a superficial aesthetic which will be discussed and agreed upon as well as the direction of the acoustics design. The RFZ (Reflection Free Zone - Peter D'Antonio) design criteria is the most common today followed by modified versions and even the obsolete LEDE (Live End Dead End - Don & Chips Davis ). Note: I also design to NE (Non-Environment - Tom Hidley. Sam Toyoshima, Philip Newell, and several others use this approach) specifications, and cutting edge Ambechoic (Peter D'Antonio - George Massenburg). Regardless of the design philosophy, the acoustics will (must) be balanced and neutral in the control room.

Most designs that I do, unless specified, will be my own The Balance design technique. The Balance incorporates past and current knowledge of Control Room Design into one beautiful and functional system.

A different technique is applied for Tracking Rooms where 'areas' in the tracking room can have acoustics favoring certain instruments or the entire tracking room can be designed with variable acoustics.

4. Finish & Testing: After the studio is built; acoustics & equipment in place, testing will be done. After analysis, problem areas will be identified & addressed.

** Years after your project is completed I plan on being here to answer your questions and/or concerns. It is my intention to create a relationship that will continue throughout your career.

Late note: at about the beginning of the year my book was stolen and placed on a free download site against my will or permission. I have written to the owners of that site but they are obviously pirates that care about nothing but destroying free enterprise and the planet. If you have recieved a copy of my stolen book I would appreciate a Donation to pay for my work, intellectual property, and so that I can continue my research. I am not funded otherwise. Thank you.

Please sign my guestbook ! - and view comments & testimonials.

I appreciate your comments. They will help to make the website and services better. Thank you.

A little history...

I have personally worked with many great audio engineers, producers, musicians, & studio and electronics designers throughout my career. I've designed studios, performed technical service, and/or produced or engineered records for/with: Eddie Kramer, Byron Gallimore, Ray Kennedy, Max T. Barnes, Randy Thomas, Bob DiPiero, Dennis Morgan, Gene Breeden, Owen & Bobby Bradley, Wayne Carson, Hank Cochran, Michael Lunn, Richard Dodd, Hal Rugg, Bernie Leadon, Mark O'Connor, Jim Mckell, Gary Talent, Marshall Morgan..... I have also designed and built custom audio electronics for many studios and performers including Billy Gibbons, Mark O'Connor, Paul Simon, and Organic Audio.

I began my career in 1971 working with small bands from Dallas/Ft. Worth, Cincinatti, Ann Arbor, Boston, then in France with ex-Fleetwood Mac member, Jeremy Spencer (1974). I toured Belgium, France, Germany, and Italy doing live concerts. I worked as assistant engineer at ABC recording studio in Paris, France & Bobby Solo's Studio in Laurentina, Italy (Rome - 1975-6). I had my own business repairing and re-building amps in London and the Midlands (Leicester & Birmingham), England, and also doing studio work & live performance sound (1976-1980).

I owned & operated JHB Sound Productions recording studio in Harker Heights, Texas (1984-1986) and engineered live concerts for The Judds, Michael Martin Murphy, Tanya Tucker, David Clayton Thomas, etc. In 1986, I was hired as chief engineer by Bob Millsap at Ironside Studios in Branson, Missouri and there worked with Rodney Dillard, Ray Price, Shoji Tabuchi, Tommy Overstreet, Sissy Lynn daughter of country music legend Loretta Lynn, and many more. In 1989, I created Brandt Audio Devices in Nashville, Tennessee and designed & installed at least two dozen recording studios in the Nashville area (1990s). Brandt Audio Devices was sold in 2008 and is now Organic Audio.

In 1998 I installed Blue Heaven Studios in Salina Kansas with Neil Muncy and made custom modifications to the Neve console. In 2004 I built Song Garden Studios in the Detroit area, and in 2008 I have relocated to Jakarta, Indonesia. I now live in Bekasi (Jakarta suburb) with my wife Erika, son Ari, & daughter Nadine.

I currently post on several forums -JH Brandt Studio Design Forum, GearSlutz, HomeRecording, TapeOP, SOS forum, Musitek (Indonesian), Home Theater Shack, and Ethan Winer Acoustics Forum. On all the forums, I do my best to help folks like you with their commercial studio, home studio, home theater, and private audiophile listening rooms.
