Accusonus Software Optimized for Cadence DSPs

The Accusonus Focus-MDR and Focus-DNR speech enhancement software has been ported to and optimized for Cadence Design Systems' Tensilica HiFi Audio/Voice digital signal processors (DSPs). The Accusonus software provides an integrated solution for reverberation and noise suppression.

The Focus-MDR and Focus-DNR speech enhancement products offer a single- or multi-microphone approach to suppression of reverberation, as well as direct and ambient noise.

Tensilica HiFi Audio/Voice DSPs offer support for more than 140 audio/voice software packages and more than 70 partners.

"Our software provides speech quality improvement for far-field use cases, when there's a longer distance between the user and the device. System designers can take advantage of our patent-pending reverberation and ambient noise suppression solution that utilizes multi-microphone configurations and integrates principles of DSP, room acoustics and psychoacoustics," said Elias Kokkinis, chief technology officer at Accusonus, in a statement. "Porting to the Tensilica HiFi Audio/Voice DSP made sense because of high customer demand and its highly optimized architecture geared towards more efficient execution of audio and voice codecs and pre- and post-processing modules."

"Accusonus has a unique and compelling solution for the problem of room reflections and reverberation that improves the voice experience quality of mobile devices," said Larry Przywara, group director of audio/voice IP marketing at Cadence, in a statement. "By collaborating, Accusonus and Cadence can offer our mutual customers the Focus speech enhancement software optimized for the HiFi DSP architecture, plus the advantage of a significantly lower frequency enabling lower power compared to other architectures."
