IoT Audio



Audio industries need Audio Platform Boards capable to perform with Hi-Res Audio, and focused on the implementation of IoT.
Therefore, it is necessary to count with a simplified but efficient and high performance audio platform, with WIFI/BT connectivity, and that is also capable of supporting 196k/32bit PCM & DSD DAC.
With the possibility of adding DSP capabilities to increase customers portfolios into high-end products.
And if needed, adding on-edge performance capabilities to complement the audio system into Voice Assistants.

This application receives video and Hi-Res audio signals from WIFI or Bluetooth, even from DMICs.
Then it processes them and sends a response to displays, speakers or any other audio or video output.
It should also count with an external Audio Codec that could support different audio formats.

Use Cases

The audio industry has been evolving through the years. Thanks to this evolution, the industry is now focused on Hi-Res Audio, & the implementation of IoT for streaming and other type of services.

  • Some of the possible uses could be:
  • Audio Streaming.
  • Audio Processing.
  • Audio Files Storage.
  • Portable Audio Systems.
  • Personal Assistants.
  • Voice Assisted Systems.
