Software brings clarity to speakerphone
The Aura Mobile BT Bluetooth conferencing device from Spracht uses SoundClear from Acoustic Technologies.
This announcement extends compliance to the C55x DSP.
This compliance is especially helpful for applications such as 3G mobile phones that use TI's OMAP processors, which integrate a C55x DSP core with an ARM processor onto a single chip.
"Extending SoundClear software's eXpressDSP compliance to all TMS320C5000 platform members gives our customers confidence that our algorithms are easy to integrate into TI DSP-based applications that demand improved sound quality", said Greg Eslinger, General Manager, Software Solutions Group at Acoustic Technologies.
"Integrated speakerphone capability is a key component in next generation mobile phones, and there is tremendous demand for improvements in both performance and sound quality".
"SoundClear software is essential for enabling high quality 3G video conferencing".
"We are excited to work with Texas Instruments to enable customers a smooth and rapid integration process for their handset designs".
The eXpressDSP compliance program ensures algorithms are written according to the TMS320 DSP Algorithm Standard, a set of coding conventions and application programming interfaces (APIs).
This allows algorithm creators to "wrap" the code for system-ready use allowing for interoperability between algorithms.
Instead of re-engineering algorithms for each different system, algorithms are written once and easily reused by integrators.
Customers who use eXpressDSP compliant algorithms gain accelerated time to market, improved ease of use, minimal algorithm configuration time, and an additional level of comfort knowing that the product has passed compliance testing for interoperability.
"The TI Third Party Programme is designed to offer time-to-market advantages, lower development costs and accelerate development efforts for developers who build innovative products and applications on TI DSPs", said Marc Wallace, Worldwide DSP Third Party Manager, TI.
"We are excited to extend the SoundClear eXpressDSP compliance offering to the C55x DSPs.
Acoustic's SoundClear integrated echo cancellation and noise reduction DSP software provides customers with improved sound quality for telephony applications.
We look forward to continuing working with Acoustic in the future on upcoming technologies".
The SoundClear software product is a combination of acoustic echo cancellation, noise reduction, and sound enhancement with sophisticated full-duplex control, optimised for mobile handsets.
High quality voice is achieved through a combination of patented techniques including sophisticated full-duplex control, enhanced nonlinear processing, subband processing and adaptive filtering.
Annoying echoes are cancelled, background noise is reduced, and speech intelligibility is enhanced.
The SoundClear system adapts quickly to changing environments and enables natural communication flow, just like a face-to-face conversation.
