what is mono audio in phone

Mono audio is a feature that sends the same sound to both the left and right speaker or earbud, making it easier to follow any audio. It is useful for people who are hard of hearing or deaf in one ear, as well as for those who want to wear only one earbud while listening to music or podcasts. Mono audio can be enabled on Android phones by going to "Settings" > "Accessibility" > "Mono audio" and toggling it on. Mono audio tends to sound flat, narrow, and less dynamic than stereo audio, as all the audio elements are squished onto the same channel and played at the same volume.
