Ideally what I am looking for is an ethernet based voice/Audio all in one module that can hold selectable wav files (up to 10) to broadcast to an external horn speaker (max 25W) on receiving an input/trigger (up to 5 different input sources)
The unit should be powered by 12vDC
There should be an option to select a one off message or repeat message
Remote volume control is important
Ability To download custom message is desirable
Ability to connect the system via SDK to a third party system
Ability to relay a message from third party software
If it has a microphone input for 2 way audio ā¦ fantastic
Im not sure if you will be able to find an all-in-one module that will be able to pump out audio at that level.
You might have to have a dedicated ethernet network communicating to one of these WAV trigger boards via UART, it might be a bit tricky getting this setup with multiple controller boards.
Getting a solution made up for this would likely best be done by an electronic engineer or someone that well into audio electronics. Iām not too sure of any companies that would be able to help with this one sorry, another member of the forum may be able to jump in and help out!
