TapNoiseA key press sound plays when a key goes down. A release sound adds a second, softer event as it comes back up. The combination can make virtual typing feel more like hearing both parts of a physical switch movement.
Listen to a slow press first
Press and hold a letter briefly, then let go. That separates the two moments so you can hear what the release setting contributes. Compare with the setting off before moving to normal typing.
During fast writing, down and up events overlap with other keys. A release layer that sounds pleasing slowly may become too busy at your usual pace. Use a paragraph containing punctuation and spaces rather than repeating one letter.
When to keep it simple
Turn release playback off if you want a cleaner rhythm, if you are typing over a podcast, or if every small sound pulls your attention away. You can also lower the overall app volume before deciding.
A release sound is an audio preference. It does not change macOS key repeat, the keyboard’s physical travel or the time at which an app receives text.
Change it in TapNoise
Use TapNoise’s Key release setting alongside its volume control. Compare the same theme with the setting on and off; changing themes at the same time makes the difference harder to judge.
For physical versus virtual feedback, see sound apps versus mechanical keyboards. If the problem is a key repeating while held down, change macOS key repeat instead.
