When about to save the recording the feature to toggle Voicemod Mic or Desktop is great but when the audio balance is bad between the sources we're missing a volume slider to adjust the balance of both sounds.

In my case the audio level for the desktop is too low to be usable in my soundboard. (Even though my system sound level is 100%)

I would recommend being able to adjust the volume UP and DOWN for each recorder channel (Voice and Desktop) before saving the sound.

Alternatively, adjust the volume before recording, so you can balance the levels before hand.

If not wanting to use DBs scaling, then allow the user to set sound levels over 100% percent.
