Owners Andrew Heller (Location Digital Recording) and Gary Wood (NorCal Sound) are pleased to announce the merging of their companies to form AUDIO PRODUCTION GROUP .

Location Digital Recording (LDR) has provided more than 20 years of service to the music, theater, and corporate communications industries in the San Francisco/Bay Area.  LDR has provided professional recording, sound reinforcement and audio consulting services to many community organizations, schools, colleges, city arts and non profit arts organizations, including local orchestras and choral groups.  Principal Andrew Heller has also worked in education, teaching at the prestigious Aspen Audio Recording Institute (part of the Aspen Music Festival) and at San Jose State University. 

NorCal Sound has been earning a stellar reputation for the past 10 years in the San Francisco/Northern California market providing live sound reinforcement, broadcast, consulting and installations for many events, municipalities and organizations. Owner Gary Wood has extensive experience in the San Francisco live and recording/broadcast community as an engineer, musician, and musical arranger.

Combining the talents and enthusiasm of these veteran audio engineers was a natural. “We ended up turning to each other for help when we exceeded our individual capacities to provide the services that our clients required. Entrusting our businesses’ reputation to each other was easy, as we could see how committed the other was to providing the highest quality service, since we have each worked very hard to successfully grow our individual client bases,” said Heller and Wood.

The merge includes the firm’s move into a new 3,200 sq. ft. office/warehouse and editing suite located in the heart of the San Francisco/Bay Area. Future plans include a voice-over isolation room and a high-end fully equipped rehearsal studio for select clients.

The Audio Production Group is a user of, and an authorized dealer for NEXO/Yamaha Commercial Audio products, as well as many others.  The Nexo systems in particular are proving to be a growing resource for both the live and installation market. “We have received nothing but great responses from everybody who has heard and/or performed with our GEO-D tangent array system, and look forward to increasing its usage on the West Coast,” Wood explained.

As the Audio Production Group, Heller and Wood plan to continue providing outstanding customer support to current customers and they welcome new clients to their ever-evolving business. “This kind of work is an adventure for sure. It takes us in directions we never envisioned, with all kinds of people, projects and situations that we must be able to quickly respond to, in a positive way. With our experience and ability to provide such resources, we will continue on this path of success,” said Heller.
