What Beeped?
⨠Free Version Available âĸ $4.99 Full Unlock (2 Activations)
Instantly see which desktop application or active browser tab just beeped across all your monitors and virtual desktops:
My computer has 10 open desktops on 2 monitors. Often some hidden or even visible app beeps for some reason, and I cannot tell where the beep came from. What Beeped? solves this problem.
What Beeped? now comes with a built-in tester that will create an alert from any open app.
The free version of the app displays a pop-up alert in the upper right-hand corner of the screen and includes the built-in tester.

The pop-ups display the App name, browser tab, and the audio channel.
I hope you will pay just $4.99 to get the full program unlocked. This purchase is good for 2 activations, and includes all future updates.

Paid What Beeped? featuresThe paid version of What Beeped? logs all the alerts so, for example, you can see what happened overnight. It also allows you to switch focus to any app with one click. The duration of the banner display can be adjusted, or you can turn it off altogether and just rely upon the logs. It is important to define what is noise (a beep) and what is music. In the paid version you can ignore any continuous sounds longer than a set duration threshold. The active apps being monitored by What Beeped? are displayed, and you can ignore them by clicking on the bell icon. This helps you narrow down the source. In the paid version, apps that are streaming continuous audio are automatically identified. |

âšī¸ Note on Browser Tab Audio: Because modern web browsers combine audio from all tabs into a single system audio stream, What Beeped? identifies a specific background tab whenever it is actively streaming media or displaying a speaker icon (
đ). If a hidden background tab plays a brief notification chime without a speaker indicator, What Beeped? accurately identifies the browser and window and displays the title of that window's currently active (visible) tab. |

đ Version History & Changelog
- Background Tray Persistence Fix: Resolved an issue where closing the configuration window (X) could allow the background monitor to exit or enter App Nap 10â15 seconds later across Windows, macOS, and Linux.
- Thread-Safe Browser Tab Inspection: Moved UI Automation and AppleScript browser inspection off the UI thread with smart caching to prevent background COM/AppleEvent crashes.
- PulseAudio / PipeWire Stability (Linux): Eliminated re-entrant C callback queries during rapid audio stream bursts.
- Automated Crash Diagnostics: Added automatic crash and unclean-exit telemetry reporting across all platforms.
- Live Stream Threshold & Embedded Web Media (v1.1.4âv1.1.5): Added duration threshold suppression for continuous music/video streams and expanded embedded HTML5 media detection.
- Universal Browser Tab Audio Detection: Generalized acoustic detection across all Chromium and Safari browsers to automatically identify active, audible, and notification tabs worldwide without geographic or market clock dependencies.
- 1-Click Background Tab Switching: Alert banners in the Free version prompt the In-App Purchase sheet to unlock instant 1-click background tab focusing.
- Smart Expired Session & Auth Filter: Automatically filters out dead login, logout, and session-expired URLs (such as Schwab timeout screens) so idle authentication pages are never reported as sound sources.
- Passive Foreground App Protection: Prevents passive foreground desktop utilities (such as Kid3, Finder, Xcode, TextEdit, and Preview) from mistakenly capturing background browser and communication alerts.
- Continuous-Stream Burst Detection: Dynamic 2.0-second audio stream resets allow discrete periodic chimes to trigger reliably.
