Tensilica and Acoustic Technologies Extend Partnership to Deliver Complete Wideband HD Voice Processing Solution

Acoustic's wideband SoundClear Voice software has been optimized for the HiFi family of DSP (digital signal processing) cores to provide advanced multi-mic noise reduction and full-duplex speakerphone performance. SoundClear Voice is shipping today in leading smartphones and other mobile devices and accessory products.

Acoustic's SoundClear Voice solutions are broadly adopted by leading consumer electronics vendors, stated Larry Przywara, Tensilica's senior director of multimedia marketing. Their HD voice solution ensures mobile users get the best possible call quality as network operators and mobile device makers rollout wideband HD voice on their networks.

Acoustic Technologies' voice processing solution is proven with tier one smartphone vendors, and the world's largest network operators, to deliver high quality voice performance in handset, speakerphone and headset modes. The HD multi-mic noise cancellation includes Acoustic's InstantAdapt feature, dynamic microphone balancing technology and FlexEQ equalization to deliver clear speech anywhere. Wideband voice doubles the sampling rate of narrowband voice to deliver expanded frequency response at both lower and upper ends of the voice spectrum. The dramatically improved voice quality improves the user experience on mobile networks that have deployed HD voice and for VoIP applications. The improvements in sound fidelity and clear speech also improve recognition rates in noise for ASR (automatic speech recognition) applications.

The HiFi DSPs are ideal for running our advanced HD voice solutions for smartphones requiring best-in-class multi-mic noise reduction and speakerphone performance, said Bob Ackmann, CEO of Acoustic Technologies. The HiFi DSPs offer leading DSP performance, low power and high quality tools that enable us to deliver optimized wideband voice solutions to our customers.

Tensilica's HiFi Audio/Voice DSPs are the leading audio/voice DSP IP cores, licensed by over 50 customers including five of the top 10 semiconductor manufacturers and many leading system OEMs. The HiFi Audio/Voice DSPs support over 100 audio/voice software packages with very efficient processing at low power and they are part of Tensilica's growing line of dataplane processors (DPUs) that efficiently do the challenging, compute-intensive tasks in SOC designs.
