Liberman Sound has been in business since 1988 repairing professional audio and film editing equipment. We specialize in providing the highest quality repairs and modifications possible with state-of-the-art equipment. In 1995 we were one of the first businesses in the world to receive the new Audio Precision System Two, and in 1998 we upgraded our unit to the Audio Precision System Two Cascade with 24 bit 96 kHz capability.

Adam Liberman, owner and engineer, has broad experience in audio. He has worked extensively in film production and post production sound, theatrical sound design, computer audio testing, radio production and engineering, and live music and nature sound recording.

He worked in engineering and repair at SRO (a film post production house) in San Francisco from 1983 to 1990, and KPFA radio in Berkeley from 1984 to 1997. From 1985 to 2007 he serviced KEM and Moviola flatbed film editing machines throughout the SF Bay Area. In the 1990’s he worked as the lead computer troubleshooter in the product test lab at PC World (the largest computer publication in the world), and authored ground-breaking articles on sound cards that included the most rigorous testing ever done by a major magazine at the time, and which exposed the major deficiencies in the cards for the first time in the mainstream computer press.

From 2007 to 2012 Adam worked at Audio Precision in Beaverton Oregon as a Technical Writer and edited their Audio.TST newsletter, and subsequently from 2012 through 2016 was a Technical Support Engineer. He is a member of the AES (Audio Engineering Society) and the IEEE (Institute of Electrical and Electronics Engineers).

Adam currently maintains the recording equipment for sound mixers on major feature films and TV shows (past shows include Desperate Housewives, Nash Bridges, and The Wonder Years), with a specialty in Sonosax mixers and recorders. In the past he also maintained recording equipment for radio stations and news reporters around the world; sound equipment for major film studios and documentary filmmakers; film sound and editing equipment for many schools and universities; and professional and high-end consumer gear for many others.
