Sound effects
PostRoll can play short tone chimes when you send a message, receive one, or get mentioned. Off by default, opt-in per user.
Turn them on
Section titled “Turn them on”- Find the user panel at the bottom of the conversation list — your avatar, name and status.
- Click the sliders button (Preferences).
- Under Behaviour, toggle Sound effects.
The other preferences in that sheet — density, text size, clock format, the members column and avatars — are covered in Appearance and layout.
The setting is per-user, not per-conversation — flipping it once turns chimes on or off everywhere in chat.
What you’ll hear
Section titled “What you’ll hear”- Send — a brief downward blip when your own message is sent.
- Receive — a slightly higher blip when a non-self message arrives in the active conversation.
- Mention — a two-note chime when someone @-mentions you.
Tones are synthesized in your browser — nothing to download. Volume is fixed and intentionally low so they won’t startle you.
Browser silence
Section titled “Browser silence”If your tab is muted at the OS or browser level, the chimes are silenced too — there’s no override.
Reduced-motion compatible
Section titled “Reduced-motion compatible”Chimes are independent of motion preferences. The reaction-pop animation honours your system’s reduced-motion setting; sound effects don’t (they’re sound, not motion).
