Accusonus gets 60% reduction in computational cost of speech enhancement software

Cadence Design Systems, Inc. (NASDAQ: CDNS) and Accusonus Inc. (Lexington, MA) said they have announced that the Accusonus Focus-MDR and Focus-DNR speech enhancement software has been optimized for Cadence® Tensilica® HiFi Audio/Voice digital signal processors (DSPs).

Accusonus was able to achieve a 60 percent reduction in computational cost as measured in megacycles per second (MCPS) without any loss of quality. With these optimizations, the Accusonus two-microphone embedded joint de-noise and de-reverberation software products reduced the computational requirement to as little as 4.8 MCPS, making them among the most efficient implementations in the market.

The patented Accusonus algorithms eliminate noise and reverberation while significantly improving speech quality to make conversations intelligible, even when there´s a large distance between the speaker and microphone.

The Tensilica HiFi DSP is the most widely used licensable audio/voice/speech DSP family, with support for over 160 proven audio/voice software packages and over 75 software partners in the Tensilica Xtensionsâ„¢ partner program.
