I think BATC should add a static noise sound when pressing your keybind to talk to act instead of that bling I find that the bling kind of doesn’t really help with immersion and I think adding an option to turn it into a static sound instead would sound way better.
Or an option to turn it off much better for me

Thank you for your suggestion - please note you can turn off the noise completely by turning off UI sounds within the BeyondATC options. We will review the static noise suggestion internally.
