Handheld product developers who are looking for a way to enhance the audio performance of portable audio players, mobile phones, and PDAs can now make use of new technologies on the OMAP platform from Texas Instruments that promise to deliver robust, panoramic sound images with enhanced bass as well as improved clarity of the high frequencies.
SRS Labs' WOW technology, which is now available on TI's new OMAP5910 device, is specifically targeted at devices with one speaker, two speakers, headphones or ear-buds. SRS Labs unveiled its latest WOW implementation at TI's Developer Conference in Houston last week, where the company demonstrated its audio enhancing capabilities on TI's OMAP1510 as well as on the TMS320C54x family of DSP.
SRS also showed off its Voice Intelligibility Processor (VIP), which has been designed to improve the intelligibility of voice in cell phone applications to enable calls in noisy environments. The technology reportedly can be applied to mobile phones, PDA devices, hands-free telematic devices in cars and other voice-related product markets. Both VIP and WOW are eXpressDSP compliant on the TMSC320C54x and C55x platforms from Texas Instruments as well as TI's OMAP platform.
In addition, SRS Labs a multichannel decoder technology called Circle Surround II that is capable of delivering up to 6.1 channels of audio from any mono, stereo and matrix surround encoded audio content. The technology, which was run during the conference on TI's TMSC320C67x platform, also incorporates patented techniques to improve the clarity of center channel dialog and provide bass enhancement, claims the company
