Audience

Intelligent Voice Processor

Using proprietary core technology based on the intelligence of the human hearing system, the Audience Voice Processor delivers the most powerful and robust noise suppression technology available today, and provides a full suite of voice quality improvements for mobile handsets and other mobile devices. Whether the noise source is in the caller’s environment, or originating from the other end of the call, the Audience Voice Processor can eliminate most noise, such as airport PA systems, restaurant noise, car noise, or music and background conversations. In addition to advanced noise suppression, the Audience Voice Processor provides acoustic echo cancellation (AEC) and voice equalization (VEQ) to further enhance voice quality. The result is vivid voice communication in places never before imagined. In addition, the Audience Voice Processor is a key enabler for next generation services in 3G mobile networks such as voice dialing, and “eyes-free” applications like voice search.

The low power, small footprint of the Audience Voice Processor is designed to easily integrate with all mobile handset form factors, baseband chipsets, and cellular networks. It is a highly integrated and compact single chip integrating a powerful custom DSP voice processor, audio peripherals and control interfaces.

Voice Processor Value

Designed around a single, purpose-built DSP, the Audience A1010 Voice Processor delivers the power of the human hearing system in a highly optimized hardware and software solution. The A1010 sets the benchmark in five critical elements of an advanced noise suppression solution.

Instantaneous Noise Suppression - Enables Clear Communication Everywhere

  • Transmit side removes stationary & non-stationary local noise such as PA systems, telephone ringing, background music,    and street noise enabling people to be heard in noisy places
  • Receive side removes stationary & non-stationary noise from caller’s voice enabling people to hear in noisy places
  • Instantaneous convergence time removes fast changing noises as quickly as they arise

Vivid Voice - Delivers Clear Speech in Noisy Environments

  • Increases voice quality by .77 MOS in noisy environments
  • Advanced acoustic echo cancellation enables simultaneous (full duplex) conversation in speakerphone and video telephony modes
  • Voice Equalization boosts incoming voice over local noise based on the type and level of background noise

Ease of Integration - Designs-in Easily to all Mobile Handsets

  • FlexMic provides maximum flexibility to handset manufacturers for ID design and microphone placement
  • Auto microphone calibration allows the use of standard Omni directional microphones and eliminates costly calibration and testing during handset manufacturing
  • Digital microphone support enables the handset manufacturers to use smaller and higher performance microphones where required
  • Interoperates with all audio codecs and baseband platform architectures

Efficient Platform - Works Well With Limited Space and Power Budgets

  • Compact and low-pin count package fits into even the smallest handsets
  • Sleep mode reduces power by shutting down power when not in use

Extensible Architecture - Enables Differentiated Voice Services

  • Supports all consumer mobile handset usage modes: close-talk (handheld), far-talk (speakerphone), and video telephony
