Introduction

This application note provides general information of the IS2083SoC/BM83 Module, covering noise reduction with high performance and Acoustic Echo Cancellation (AEC) with advanced signal processing techniques, sophisticated voice and audio enhancement functions, filtering, equalization and audio effect processing. In addition, it offers fine tuning the AEC and Noise Reduction (NR) parameters for different applications during product development. The Digital Signal Processor (DSP) configuration tool (IS208x DSP GUI configuration tool) provides step-by-step guidance for setting the DSP features according to desired requirements of the system designers.

The IS2083SoC/BM83 Module is designed for high-performance signal processing, providing an excellent user experience for voice or audio. The fundamental modules of the IS2083SoC/BM83 Module include the following:
  • Filter
  • Stationary NR
  • Spk gain
  • MIC gain
  • AEC
  • I2S
  • AES (optional)
  • Sound effect (optional)
Note: The user can adjust the optional modules as per the customer requirements.
The AEC function is available during the Synchronous Connection-Oriented (SCO) link connection.
