Virage Logic Sonic Focus Adaptive Volume for Normalizing Audio Levels

Virage Logic’s Sonic Focus Adaptive Volume audio volume normalizing software normalizes audio levels of movies and music to reduce the need for frequent volume adjustments by the consumer and thereby enhances audio performance in consumer electronics. It has already been licensed for use in PCs, Phone Applications, and USB peripherals. Adaptive Volume is available for PCs (Vista and Windows 7 OS) and a number of embedded processors, such as Virage Logic’s ARC AS 211SFX.

Unlike other normalization techniques, Virage Logic’s Sonic Focus Adaptive Volume employs a predictive algorithm based on human perception of loudness. Adaptive Volume seamlessly adjusts the audio level when switching among DTV programs, movies, music and voice, both reducing uncomfortable loudness and boosting soft audio content. For example, Adaptive Volume detects and corrects any volume fluctuation between a digital television (DTV) program and a commercial advertisement. Adaptive Volume also adjusts PC audio when a user transitions from a VoIP call to watching internet based content, a DVD or Blu-ray movie or listening to music.

Consumer electronics manufacturers can implement Adaptive Volume with the full range of Virage Logic’s Sonic Focus audio enrichment products to shorten time-to-market and time-to-volume of products that give consumers unsurpassed audio enjoyment. Original Equipment Manufacturers (OEMs) can also benefit from using the Sonic Focus product mastering tools and audio enrichment IP provided by Virage Logic. These unique tools allow companies to customize audio quality and the magnitude of the volume normalizing effect, thus optimizing the whole audio chain, including audio transducers, speaker cavity and industrial design. This entire tool set provides companies with the ability to produce the very best audio quality and consumer experience in end products such as DTV and PCs.

Adaptive Volume is the newest offering in Virage Logic’s Sonic Focus portfolio of Audio IP solutions. It joins Virtual Bass which significantly enhances the bass response of speakers that have limited ability to produce bass without compromising voice integrity or detail; Adaptive Dynamics which helps restore clarity and fidelity of compressed audio in today’s music, movies, and games; Extrapolator which expands stereo audio to a lifelike multi-channel sound stage using advanced physical modeling techniques; and X-Matrix which creates a surround-sound environment on stereo speakers or headphones for a truly enjoyable movie or concert experience.
