Hi All,

I wonder if anyone could tell me if the Teensy 3.2 is capable of detecting an audio signal. This is the output from a VHF radio. It is 2v peak-to-peak.

I just need to sense whether there is sound present or not. This is to detect if a transmission is coming through on a radio. It is just a single mono wire that is line level.

Could this wire just be spliced in to an analogue port on the teensy and if the analogue value reads above a certain value then it indicates that audio is present.

I am not sure if any other components would be required.

Many thanks in advance.
