Feature request: Allow listening to my sound output

[jonaseberle]

Problem

I am looking for reassurance that my voice is working when starting a controlling session. I am currently doing "radio checks" on other controller's frequency because I am quite regularly not audible.

I am able to check that the microphone works in general with other programs, but I am currently not able to "hear" what VectorAudio "hears".

I would really like to listen to my voice - also to hear the effect of these settings:

Suggestion

A "Loopback" function:

Do you see any technical possibility to listen in to the microphone input before it is being sent to the audio server? input -> VectorAudio -> output

Or could we even listen in to our voice channel on the server while we are transmitting? Is that technically feasible? input -> VectorAudio -> audio server -> VectorAudio -> output
