system_audio_meter 0.4.2

Real-time desktop audio level meter for Flutter with input/output device monitoring.

0.4.2

• Improved Windows device integration so input and output capture re-sync more reliably after device changes.
• Added fuller Windows device refresh handling with connect and disconnect event propagation aligned with the macOS behavior.
• Fixed a Windows native build failure caused by local variable shadowing in the silence-detection argument parsing path.
• Preserved the existing public Dart API while improving Windows stability for silence detection and reconnection scenarios.

0.4.1

• Refactored the example application into smaller reusable widgets and pages.
• Extracted meter-related UI components from main.dart into dedicated widgets.
• Added MeterSection, PeakMeter, DeviceOption, ErrorCard, and SilenceStatusCard.
• Introduced a dedicated MeterPage to improve separation of concerns.
• Improved maintainability, readability, and future extensibility of the example application.
• No changes to the public API.
• No functional changes to audio metering or silence detection.

0.4.0

• Added optional silence detection for system output with configurable threshold and minimum duration.
• Added the silenceEvents stream plus the AudioSilenceEvent and AudioSilenceEventType Dart models.
• Added enableSilenceDetection() and disableSilenceDetection() to the public API.
• Integrated silence event emission into the Windows and macOS native metering pipelines without storing audio buffers.
• Updated the example app and README to demonstrate silence detection.

0.3.1

• Improved the README for pub.dev and pointed users to the official documentation website.
• Added package metadata for repository, issue tracker, and hosted documentation.
• Added MkDocs-based documentation publishing infrastructure for GitHub Pages.

0.3.0

• Added macOS output metering using Core Audio taps and a private aggregate device.
• Added macOS input metering using CoreAudio device capture.
• Added macOS device connect/disconnect monitoring and active-meter reattachment behavior.
• Added explicit microphone-permission handling for macOS input metering.
• Documented macOS 14.2+ requirements, privacy keys, and sandbox entitlements.

0.2.0

• Added AudioDeviceEvent, AudioDeviceEventKind, and AudioDeviceFlow.
• Added deviceEvents so Dart can listen for input/output connection and disconnection changes.
• Added automatic Windows reattachment logic for active input and output streams when devices return.
• Added selected-device recovery by friendly name when Windows recreates a device with a new deviceId.
• Added UI-side auto-refresh and auto-resume behavior in the example app for reconnectable devices.
• Improved disconnect handling so meters reset cleanly to 0 / 0 while waiting for reconnection.

0.1.1

• Added AudioInputDevice and input-device metadata on AudioLevels.
• Added input device listing, selection, and current-device queries to the Dart API.
• Added inputLevels, startInput, stopInput, and isInputRunning.
• Added Windows WASAPI input capture support alongside the existing output loopback path.
• Expanded the example app to demonstrate both output and input metering.

0.1.0

• Initial public release.
• Added the desktop SystemAudioMeter.instance API.
• Added AudioLevels and AudioOutputDevice models.
• Added MethodChannel and EventChannel integration for meter streaming.
• Added Windows WASAPI loopback support for real-time stereo peak levels.
• Added macOS system output metering with Core Audio taps and a private aggregate device.
• Added a safe unsupported stub for Linux.
• Added an example app, screenshot assets, and README documentation.
