Button sounds succeed when they communicate action and state instantly. Use the library to find a close match, then prompt variations that fit your UI speed, surface material, and how dense the rest of the mix is. For example, a glass tap for a phone screen needs a shorter tail than a mechanical press on a kiosk, and confirm vs error should differ in pitch and bite.
Match the action type: tap, press, toggle
Describe the interaction first. A quick tap wants an ultra-fast transient, while a longer press can carry a slightly heavier body. Toggles often read best with a two-part motion: down click then release.
- For taps, ask for very fast attack and near-zero sustain
- For presses, add a small low-mid thump and slightly longer decay
- For toggles, prompt two events or a subtle release click
Choose a material that matches the UI surface
Material language guides texture. Plastic feels snappy and bright, rubber feels muted, metal feels tighter and more pointed, and glass taps can be thin with minimal low-end. Keep the tone consistent across your interface so it feels designed, not random.
- Plastic: crisp high-end, short tail, light grit
- Rubber: rounded transient, reduced brightness, softer impact
- Metal or glass: sharper bite, cleaner edges, minimal low-end
Control tail and space so it does not smear
UI clicks are usually dry. If you need environment, keep reflections subtle and short so the sound remains readable in fast navigation. For public-space panels, a faint hallway reflection can help sell location without turning into reverb wash.
- Ask for dry close-mic clicks for menus and app flows
- If adding space, keep reflections short and quiet
- Avoid long decays that overlap rapid button repeats
Separate confirm vs error without being annoying
State sounds should be distinct at low volume. Confirm can be brighter and smoother, while error can be drier with a pitch dip or a harsher transient. Keep dynamics controlled so frequent UI use does not fatigue the listener.
- Confirm: clean tone, smooth release, consistent loudness
- Error: tighter click, more bite, subtle downward pitch cue
- Avoid overly loud spikes that clip or mask dialogue
