v1.1.0 — Direct Capture (volume-independent)

What's new

Direct Capture mode (default)

Audio is now captured via WASAPI Process Loopback (ActivateAudioInterfaceAsync), which taps the audio stream at the OS mix stage — completely independent of the Windows master volume slider. Even if an operator mutes the PC to avoid noise, alert audio is still streamed to the conference bridge.

Requires Windows 10 20H2 (build 19042) or later.

Rendered Capture mode (fallback)

The previous WASAPI loopback behavior (via NAudio) is retained and selectable via config:

"audio": { "captureMode": "rendered" }

Use this on Windows 7 / 8.1 machines where Process Loopback is unavailable.

Upgrade

Run the new MSI directly — the previous version is uninstalled automatically and config.json is preserved.

msiexec /i LoopcastUA-1.1.0.msi /qn

Default config change

audio.captureMode defaults to "direct". Existing installs without this key will also use "direct" after upgrade (the default in code). If you need the old behavior, add "captureMode": "rendered" to your config.json.

v1.0.2

Initial public release.
