Fixes Loudness, Preserves Content

AMSTERDAM, NETHERLANDS — Linear Acoustic, the leading worldwide authority in DTV audio processing and transmission solutions, is introducing the CARBON™ Hybrid Metadata Loudness Controller at IBC 2009 (Stand 8.D29).

Loudness control and audio encoding are combined by a patent-pending hybrid process that allows infinitely variable adjustment between permanent and reversible control of source audio loudness and dynamic range. Capable of working with any audio codec that supports metadata, the premier version of Linear Acoustic CARBON maximizes the effectiveness of metadata within the Dolby® Digital (AC-3) system.

“This groundbreaking technology enables audio to be sent to consumers with broadcaster regulated control of loudness while still preserving the original audio content,” says Tim Carroll founder and president of Linear Acoustic. “This allows consumers to choose audio reproduction that matches their environment - from full surround sound systems to small kitchen TVs, to mobile or hand-held devices.”

Linear Acoustic CARBON accepts encoded or baseband PCM audio via AES or HD/SD-SDI connections, and optionally supports processing of audio at the transport stream level via DVB-ASI connections. MPTS via Gigabit Ethernet (GigE) will be supported for cable and satellite applications.
