in addition to what everyone else said about muting a microphone being a totally legit thing in English, you _can_ mute a keyboard. For example, adding soft foam to soften the hit when it bottoms out would mute your keyboard somewhat. Obviously this app doesn't "mute the keyboard" but since we're being pedantic, it's not accurate to say it can't be done. keep in mind mute does not only mean "to silence" (verb form). It's also "deaden, muffle, or soften the sound of." So, practically speaking, there are very few physical objects that produce sound that can't be muted.
