85. us enables the audio processor to modify its own architecture in real time and in response to ever changing program content Simply stated Sensus has the ability to sense what must be done to signal in order to best tailor it for the following codec As program content changes it rearranges the algorithms to accomplish this goal The uniqueness of the Sensus technology makes it highly suitable not only for codec pre conditioning or provisioning but also for a range of other highly specialized signal processing challenges The following is a discussion of how Sensus technology can be applied to a coded audio environment Codec Provisioning The codec is now a common denominator in the world of audio and broadcasting Digital broadcasting HDTV HD Radio DAB DRM podcasting webcasting cellcasting and downloadable music files all employ a form of codec based data compression in order to minimize the bandwidth required to transmit data The necessarily low bitrates utilized by these mediums presents a tough challenge for any audio processor used prior to a codec Traditional dynamics processors were designed to fulfill the requirements of a medium where the functions were generally static That is they were well suited to the rather simplistic peak control OmniaONE Multicast Use and Operation Manual Version 0 90 9 and bandwidth limiting methods that were required for analog broadcasting as well as for
86. us trouble for a codec Quality Versus Density The primary trade off between quality and artifacts will be located within the processor s limiter sections With increased depth of limiting intermodulation distortion increases and the fast activity of the limiters causes the audio to sound tight or squashed If limiting is taken to the extreme the sound can be perceived as pumping breathing dense or mushy It can even induce exaggerated swish swirl artifacts from the codec Please remember that the core objective of the OmniaONE Multicast product is maximum intelligibility at low bitrates and processing that creates heavy density can completely mask that effort A codec provisioning processor is in quite a different role than a conventional on air processor It is far more of a tool than a weapon OmniaONE Multicast Use and Operation Manual Version 0 90 27 The following sections are provided to assist you in designing personality of your sound As we said earlier there is no precise recipe for setting up audio processing because each application is different However there are a few basics that we can share with you that can help get you to where you want to go Setting up processing for the absolute best end product usually requires a concerted effort some extended periods of critical listening and making a few intelligently chosen and subtle changes over time It will be time and effor
