Lancaster, PA (April 16, 2009)–Linear Acoustic is introducing its AERO.qc at the 2009 NAB Show this month.
The new audio quality controller combines loudness and reformatting tools required for maintaining a consistent viewer experience, including ITU loudness measurement, loudness correction, selective upmixing, metering, and monitoring.
AERO.qc is designed for operational integration when deployed at the head of the program chain–during ingest, origination, or in-house production–where correction can be applied manually or automatically to maintain program consistency.
Linear Acoustic recommends the correction of level and format anomalies as soon as they can be detected in the broadcast chain in order to maintain quality and ensure program consistency. Further, the judicious application of loudness control and appropriate reformatting at the earliest possible stages can prevent undesired artifacts being unnecessarily introduced by downstream processing.
AERO.qc is part of a wider Linear Acoustic initiative to provide a range of measurement and manipulation solutions that will allow broadcasters to correct format and level inconsistencies at the time content is being created, as it moves through the facility, or as it enters from outside sources.
Designed in conjunction with processing expert Leif Claesson, AERO.qc may employ level rescaling, industry-standard Linear Acoustic UPMAX stereo to 5.1 conversion, or optional 5.1-channel multistage AEROMAX loudness control. Operator intervention can range from full manual control of measurement and audio adjustment to automated processing that requires little oversight. Pre-processing content with AERO.qc prior to in-house distribution ensures that content conforms to on-air standards.
Front panel features include menu navigation and control of volume and speaker mutes via two navigation clusters, while a color TFT display shows ITU BS.1770 loudness metering with peak and VU ballistics along with metadata parameters. This allows the setting of a reference dialnorm level, metering of incoming content, and the rescaling of audio where necessary.
