Job Summary:
Sensory is seeking a polished, proactive and senior level Acoustic (Audio) DSP Engineer with extensive experience in audio processing for varied acoustic environments to work in algorithm development such as AEC, microphone array beam-forming, Noise Reduction, gain control, etc. (...test and benchmark the algorithms in different environments including the sound booth)
Primary Responsibilities:
- DSP design and tuning for acoustic echo cancellation, beam-forming, etc. for active call quality, as well as best-in-class enhancement of speech recognition in noise.
- Support customers with transducer design, selection, placement and turning; and acoustic enclosure co-design.
- Learns and understands existing proprietary voice recognition algorithms in depth.
- Implements voice processing algorithms and related software on hardware platforms.
- Defines and implements simulation scripts for validating, evaluating, and improving the performance of algorithms.
- “Ports” existing technology software to various platforms including DSPs.
- Develops and maintains in-house and customer tools to support the application of Sensory’s voice processing.
