How to Add Mono Audio Context Menu in Windows 10
Mono audio is a special Accessibility feature of Windows 10 that makes sure that even if a listener has an issue with one ear or one audio channel, he or she will never miss a word or sound of audio playing in a stereo headset or multichannel speakers. For many years, the audio we listen to has come with distinct left and right channels. In this case, the listener receives a different audio stream from both channels with different sounds. Unlike stereo, monoaural audio plays the same stream via both channels. Windows 10 includes a native option to enable Mono audio output. You can access it faster by adding a special context menu command to the Desktop.
While this capability has been possible in media player software for quite some time by downmixing stereo or multichannel audio to mono, it hasn't been available before Windows 10 at the system level. Enabling mono audio output is useful when you are listening to audio which has only one channel, or is encoded incorrectly or if the encoded channels are incompatible with your hardware setup, as a result of which only one headphone or speaker plays the sound.
In Windows 10, the ability to turn on mono audio is part of the Ease of Access features. It can be enabled in Settings under the appropriate category.
If you often enable the Mono Audio function, it may be useful for you to have a special context menu command for that to enable/disable this function faster.
