Linear Acoustic shows new DTV audio processor

Linear Acoustic, a manufacturer of multichannel sound products for digital broadcast, announced its Aeromax:one digital television audio processing system at NAB (booth #C2151). The unit optionally supports built-in Dolby Digital (AC-3) encoding.

Inconsistent DTV audio loudness, or the so-called “loud” commercial problem, is the number one complaint of television viewers. Stations simply do not have the time to manage the huge variety of stereo and surround sound programming that viewers expect, while ensuring compliance with federal regulations.

The single-rack-unit accepts four AES pairs of audio to handle two-channel to 5.1 channel network or local audio and a separate pair of channels for SAP or visual descriptive programming. The unit can apply multiband, multistage loudness control and upmixing to the local audio, allowing it to be matched to 5.1 channel network audio, while leaving the network audio untouched.

The Aeromax:one is especially appropriate for affiliates needing a simple, cost-effective solution for local loudness control and Dolby Digital (AC-3) encoding.

AES I/O plus metadata and GPI control are standard, and a software remote will be available later this year. Available options include built-in Dolby Digital (AC-3) encoding, metadata output, and HD-SDI embedding and de-embedding.
