Linear Acoustic has updated the AERO.soft audio and loudness management system for TV stations.



audioAERO.soft is deployed on processing engine hardware and uses AoIP to connect to xNodes for completely flexible I/O. New since the product was first introduced is the option for the AMX5x2 processing instance, which provides five stereo loudness managers (2 + 2 + 2 + 2 + 2) in a single instance, allowing for a total of 15 stereo loudness managers in a single AERO.soft Processing Engine.

AERO.soft also includes the AEROMAX adaptive wideband and multiband, multistage, ITU compliant, loudness control algorithm. Loudness, spectral balance and image shifts are controlled while preserving more of the original content than previously possible. Upmixing is provided by the Hollywood-approved UPMAX algorithm, which provides a 5.1-channel audio experience from two channel sources. All instances include unique and unmatched support for SAP/DVS, local emergency audio, local voiceover and optional audio description (warble tone) functionality. ITU-R BS.1770-3 full time metering and logging is included for all programme outputs with units in LKFS or LUFS for EBU. NfRemote is included for control and display of all features and parameters. An HTTP server enables control of I/O, loudness control presets, upmix presets and individual loudness control and processing parameters using simple IP commands.
