Sure! It would be useful to know the mic level in general before hitting the mic button to train, so you can see what the level is looking like before you speak.
If you have line inputs, it would simply be easier to see the incoming level of these in RadioBOSS and note have to check the level externally (in windows mixer for example).
Also at the moment we are just streaming the audio mix, but if we wanted to just stream an input (because music is played outside of radioboss) we are unable to see the levels which are going out.
Hope it makes sense?
