Firmware Revision History

Firmware 2.0.1 (MAR/26/2025) avbtool_2.0.1_v176_20250326.swu

  • Avnu™ MILAN® Certified

  • Feature: (MIDI) Improved response to parameter change request messages

  • Feature: Faster change of sampling rate

  • Fix: 0 dBFS signals immediately following a clipped signal would continue to indicate OVR

  • Feature: Improved user guidance after change of sampling rate while streaming

  • Feature: Faster preset name changes

  • Feature (WebUI/GUI): Better visualization of peak levels when peak levels are activated

  • Feature (WebUI): Improved appearance of truncated labels

  • Feature (GUI): Add scales to mic and phones level meter background

Changing sampling rates will change the sampling rate of the device but keep existing AVB streams running with wrong stream format and audio payload due to MILAN requirements. It is highly recommended to use an ATDECC controller (Milan Manager® or Hive) to manage routing and sampling rate changes in MILAN environments.
