Turn On/Off Mono Audio auf Realme
Realme phones play audio in stereo by default, sending different channels to each speaker or earbud. If you only wear one earbud, use a mono hearing aid, or listen through a single external speaker, parts of a call, song, or video can go missing because that content only exists in the other channel.
Mono audio settings merge both channels into a single signal that plays identically everywhere, so nothing gets lost when you are not using a full stereo setup. This affects calls, media playback, and system sounds, and it does not change overall volume levels.
To enable or disable it, go to Tap on Settings ➔ Tap on Additional settings ➔ Tap on Accessibility ➔ Enable or disable Mono audio. The toggle applies instantly across the system.
Leave it off if you regularly use both earbuds or stereo speakers for music and movies, since stereo separation is what gives instruments and effects their sense of placement. Turn it on if hearing or device limitations mean one channel would otherwise stay silent.
