Real-Time and File-Based Audio Processing

For the past 15 years, Linear Acoustic® AERO-series processors have been the industry standard choice for delivering multi-channel digital television audio that assures broadcasters of meeting compliance and regulatory demands while simultaneously providing viewers with the highest quality audio experience possible. Minnetonka Audio offers its AudioTools series of file-based loudness correction and coding products, SurCode audio encoding plug-ins for digital audio workstations, and licensing of pro audio OEM solutions to prepare content for distribution world-wide.

Embraced and relied upon by local affiliate stations, content distributors, cable and satellite networks, and nearly all major over-the-air networks, real-time processors such as AERO.100, AERO.2000, AERO.10, and AERO.asi sit in the final transmission or distribution path where they effectively control unwanted loudness shifts and ensure compliance with ATSC A/85 and EBU R128 standards while still delivering a pleasing and dynamic audio experience for viewers.

Beyond their primary role as loudness managers, these products also serve as flexible signal routers offering AES I/O, HD/SD-SDI de-embedding and re-embedding, and in some products, analog I/O.  All offer the renowned and Hollywood-approved UPMAX® stereo-to-5.1 upmixing and downmixing algorithm. Some models optionally decode and encode Dolby® Digital, Dolby Digital Plus and Dolby E signals and author Nielsen® watermark encoding signals for audience measurement.

In addition to traditional hardware solutions, Linear Acoustic AERO.soft introduces the benefits of Livewire+/AES67 Audio over IP (AoIP) to television. For nearly 15 years, AoIP has been widely embraced by radio broadcasters around the world for its speed, ease of implementation and management, reliability, and a significant reduction in the wiring and cabling needed to transport and share audio throughout the broadcast facility.

In AERO.soft, all loudness control, upmixing, and coding functions are hosted on the dedicated AERO.soft Processing Engine which is ideally suited for high channel density applications. The task of interfacing AoIP with existing analog, AES, and SDI signals is managed by xNodes including the SDI xNode which offers de-embedding/re-embedding of two SDI signals to/from the AoIP domain.

Expanding further still into the world of Livewire+/AES67 is the Omnia VOCO 8, a networkable tool for managing microphone processing throughout the entire broadcast plant. Studio-grade mic pre-amps (with phantom power), up to eight switchable mic or line level inputs, highly configurable multiband processing, four mix buses, and the ability recall individual user settings or entire sessions on a network-wide basis make VOCO 8 the finest sounding and most flexible microphone processor available to both radio and television broadcasters.
