Microsemi announced that its new Timberwolf audio processor is specifically designed for Ambarella, Inc. (Nasdaq: AMBA) camera system chip (SoC). Microsemi's custom technology has been carefully designed to be the best-in-class high-definition (HD) audio solution in the Ambarella video processor suite. The new audio processor is designed using AcuEdge Acoustic Technology on Microsemi ’s innovative Timberwolf digital signal processor (DSP) platform, which has a complex set of fully integrated algorithms that allow users to communicate from the audio environment they are communicating with Extract intelligible information.
Microsemi's new ZL38AMB provides license-free, royalty-free intelligent audio algorithms. The comprehensive Microsemi AcuEdge software package accelerates time-to-market for customers with complementary reference designs and easy-to-use development tools such as the MiTuner Acoustic Echo Cancellation (AEC) tuning kit.
The Microsemi ZL38AMB device is an advanced broadband acoustic echo canceller designed to provide advanced echo cancellation, noise reduction, beamforming, and sound position detection for the growing IP camera and wearable device market. The functions of the new equipment have made important advancements to meet the growing demand in this field. According to the latest IHS research, the total shipments of the IP camera and wearable imaging market reached 21.6 million units in 2014, and it is expected that the annual shipments in the next four years will continue to grow at a rate of 30% per year to reach more than 91 million Shipped every year until 2018.
"Our second-generation audio processing solution series utilizes products of Microsemi AcuEdge acoustic technology, which brings important functions, such as a 30-meter long-field microphone and direction of arrival, so that camera users can know the position of the sound "," Said Jacques Issa, vice president and business unit manager of Microsemi. "Now, manufacturers engaged in designs based on Ambarella IP and wearable cameras can easily integrate our leading audio solutions into their designs."
ZL38AMB Acoustic Echo Canceller is a highly applicable hardware platform designed to implement intelligent audio processing for camera applications. ZL38AMB provides a powerful DSP with a dedicated hardware accelerator for voice, three digital microphone interfaces, two independent 16-bit DACs with headphone drivers, and two flexible time division multiplexing (TDM) interfaces. Pin QFN or 56 pin 3 × Middle 3 CSP package. Other features include 48 kHz stereo music playback with sound, ultra-low and standby power. It can run unattended (no controller required) and can self-direct into the configured operating state.
AcuEdge acoustic technology is a combination of various speech processing modules that can provide the following functions: 1 – eliminate acoustic echoes 2 – reduce smooth and psychoacoustic noise 3 – reduce howling noise 4 – two and three microphone beamforming 5 – sound position Detection 6-Compressor / Limiter / Extender, provides excellent performance for far-field microphones and automatic gain control (AGC) functions.
These powerful functions are enterprise-level automatic speech recognition, sound classification and other sound and audio detection-based The basis of intelligent decision-making functions. The company said that Microsemi ZL38AMB with Microsemi AcuEdge acoustic technology will be available in July 2015.
