Banking on Dolby Volume's becoming as common as Dolby Digital surround sound, Freescale Semiconductor Inc. has built the technology into its entire line of Symphony digital signal processors (DSPs). Dolby Volume turns up quiet programs, muffles loud advertisements and generally equalizes sound levels among different audio sources, such as DVD and TV. Earlier this year, Cirrus Logic Inc. (Austin) introduced an audio DSP with Dolby Volume sound-leveling technology, but only for stereo digital TV applications. Freescale's DSPs implement both stereo DTV and full multispeaker surround sound systems for home theaters.
