Product Details

The ADAU1860 is a codec with three inputs and one output that incorporates two digital signal processors (DSPs). The path from the analog input to the DSP core to the analog output is optimized for low latency and is ideal for noise canceling earphone. With the addition of just a few passive components, the ADAU1860 provides a complete earphone solution.


  • Noise canceling handsets, headsets, and headphones
  • Bluetooth active noise canceling (ANC) handsets, headsets, and headphones
  • Personal navigation devices
  • Digital still and video cameras
  • Musical instrument effect processors
  • Multimedia speaker systems
  • Smartphones

Hearable Sound Studio Pro (Rev 1.1.0)

Hearable Sound Studio Pro for ADAU1860Hearable Sound Studio Pro software is a tool for developing hearable audio solutions such as, Active Noise Cancellation (ANC), Transparency, and Audio Playback, in hearable form factors using ADAU1860. The software allows for ANC/Transparency solution tuning and evaluation of characterized headsets with ADAU1860. Users can evaluate multiple configurations (filter tunings) with hardware directly or simulate ANC performance if hardware and test environment aren’t readily available.

Hearable Sound Studio Pro is available for download from this web page. Complete software package including tuning tool, documentation and demo video are available upon completion of a Non-Disclosure Agreement (NDA) (pdf). Send your completed forms by e-mail to HSS_Lark@analog.com.
