LINEAR ACOUSTIC | LOUDNESS MANAGERS 116 AERO.file AUDIO/LOUDNESS MANAGER AERO.ile ® brings proven audio technologies developed by Linear Acoustic to the ile-based domain. Developed in part- nership with Radiant Grid Technologies, AERO.ile eliminates the need for custom hardware and integrates audio processes into existing systems and worklows. Tools can be used for ingest, managing existing libraries, conform- ing content for different playout services, or any combination. In the TV audio process, upmixing and loudness range control tools have proven most effective in the ile domain. Advanced RadiantGrid transmuxing and transwrapping enables the audio WHEN SIMPLE SCALING IS NOT ENOUGH Whether anchor-based such as with Dolby Dialogue Intelligence TM or overall average with the relative gating methods of EBU R<strong>12</strong>8, scaling aligns the anchor or overall average of content. This can easily be imagined when considering how to match a commercial advertisement with a program illed with dialogue and explosions - what do you match with what? Sometimes programs have a loudness range, that while appro- essence to be extracted from a host of popular ile wrappers, measured, scaled, and processed, then re-wrapped without disturbing other video or data essences. AERO.ile supports WAV, AIFF, MPEG 1 Layer II, MP3, AAC, ACELP, WMA, AMR and uses SurCode for Dolby ® Digital, Dolby Digital Plus and Dolby E encoding and decoding. Operator controls are simpliied to choices of loudness target, whether to use 2-channel to 5.1 channel upmixing and whether to use loudness range control. priate for a movie theatre or a premium channel, is challenging to re-purpose for delivery on other channels and especially mobile services. This is where sophisticated loudness range management techniques can be employed. Once scaling is applied to the program, the job of loudness range control (LRC) is dramatically simpliied and the effects are minimized.
TECHTALK BLOG TELOSALLIANCE.COM/BLOG AERO.mobile AUDIO/LOUDNESS MANAGER BROCHURES LINEARACOUSTIC.COM/BROCHURES AERO.mobile TM is rich audio clarity for Mobile DTV. Part of con- vincing an audience that Mobile DTV is an exciting option means providing them with an enjoyable experience. Viewers are lis- tening. AERO.mobile is designed to ensure viewers not only hear and understand content, but are surprised by the clarity. Mobile DTV must overcome physical constraints – small speak- ers and environmental issues such as background noise. In ad- dition, program audio can range from mono to 5.1 channels and from faint to screaming loud. These factors combine to impair intelligibility, make viewing tedious and cause viewers to give up. Traditional audio processing alone cannot enable diverse audio content to be reproduced effectively from mobile and hand- held devices. In fact, it can make the situation worse. Simple wideband techniques don’t do enough, and multiband systems soften important audio cues if overused – both negatively im- pact intelligibility. Linear Acoustic Mobilizer TM technology was developed based on extensive research into normal and impaired hearing in both quiet and noisy environments. By using technology from the WHITE PAPERS LINEARACOUSTIC.COM/WHITEPAPERS renowned CrowdControl TM algorithm to isolate dialogue ele- ments and combining new multiband techniques designed to preserve critical audio cues, program intelligibility is enhanced without the need for heavy handed processing. Mobilizer also provides pre-conditioning for the low bit rate HE AAC Mobile DTV audio encoder to maximize its performance at even the lowest rates. Importantly, Mobilizer technology has been carefully designed and tuned to support and enhance systems like Dolby ® Mobile which are being introduced for use within mobile receiving devices. The rugged 1RU AERO.mobile is intended to be installed directly before the mobile audio encoder in either the AES or SDI paths. Bypass relays are provided to ensure continuous service in the unlikely event of failure. A bright LED display, rotary encoder, and four control keys provide straightforward menu navigation and function adjust- ment. Dual, redundant, auto-ranging power supplies are avail- able to allow for trouble-free operation worldwide.
