However, it won't let you pick an 'output' as your input. So if you are 'always' in Mono, then you don't have adequate audio equipment or you don't have an updated device (as any modern device, for the past decade at least, natively supports Stereo).įor that matter, what you are actually talking about, the ability to select your input source is already a setting in Discord. That being said, the audio channels are controlled by your device, not by discord. In Stereo, you would hear is loudest from the right and marginally from the left, then they will cross-fade until the left is loudest and right is marginal, at which point the left will then lower its level as it gets further 'out of earshot'.

In Mono, you would hear it in both ears at the same audio level. Now let's say you were streaming a game, and a helicopter flew past you from right to left. In terms of headsets, this means you will hear them through both ears. So someone talking to you will always be in mono, or a single audio channel. So to explain the function of this, a mic for instance (in most cases) is only mono. This has nothing to do with playing multiple application's audio through a single output. The upgraded version of that is Surround, and the downgrade is mono.

'Stereo Audio' means that there are 2+ audio channels, this allows a single source to output to multiple speakers to emulate directional sound.
