Published: 9 January 2017 - Sarah Mead

Cadence Design Systems and Retune DSP today announced that Retune DSP’s multi-microphone beamforming and echo cancellation technology has been ported and optimised to Cadence Tensilica HiFi DSPs for Audio/Voice/Speech. Optimised DSPs such as the Tensilica HiFi DSP that are efficient, low power and high performance are well suited for voice-processing applications.

“We are truly excited to partner with Cadence to deliver the Voice Seeker beamforming and echo cancellation solution, as well as our All Ears voice suite on the Tensilica HiFi DSP.  This port enables a wide range of consumers to benefit from our best-in-class solutions for voice control and communication in everyday acoustic environments,” said Ulrik Kjems, co-founder and CEO of Retune DSP. “The computing capability of the Tensilica HiFi DSP allows us to deliver far-field voice control performance levels that exceed customer expectations, with simultaneous beamforming, echo cancellation, direction of arrival indication and integrated keyword voice triggering.”   

Retune DSP is part of the growing ecosystem of Tensilica partners who have ported their software to the HiFi architecture, enabling semiconductor companies and systems OEMs to get up and running quickly. Retune DSP’s Voice Seeker and All Ears audio front ends leverage Retune DSP’s unique beamforming technology that supports adaptive near-field and far-field beamforming for configurations from two to nine or more microphones. This delivers improved signal-to-noise ratios andprovides superior voice control performance, significantly improved speech intelligibility and much better overall user experiences. These solutions are ideal for applications that require best-in-class voice control or communication, including mobile phones, smart TVs, mobile and gaming headsets, digital assistants, robotics and automotive hands free.  For more information on Retune DSP’s technology, visit
