Module system_audio_ipc 

JS-bridge bindings for the M-AUDIO-SYS.2 / AUT-282 system-audio commands.

Mirrors crate::camera_ipc / crate::mic_ipc for the per-app speaker-capture path. Each function invokes a __screen* helper in index.html’s inline script, which wraps window.__TAURI__.core.invoke(...).

Structs

AudioAppView

Mirror of crates/app/src/commands.rs::AudioAppView (M-AUDIO-SYS.2).

Enums

AudioAppFilterView

Mirror of crates/app/src/commands.rs::AudioAppFilterView. The tagged-enum serde shape lets the Tauri command pick one of the three filter modes without an extra mode: String field.

ListAudioAppsResult

Result shape carrying either the typed list or a string error so the picker can render the error inline.

Functions

js_error_string 🔒

Best-effort: turn a JsValue error into a human-readable string for inline display in the picker.

list_audio_apps

Async helper: enumerate every running app SCK can see.

list_audio_apps_js

__screenListAudioApps() — returns Promise<AudioAppView[]> or rejects with a string error.

open_settings_screen_recording

Async helper: shell out to open System Settings → Screen Recording (M-RECP.6 / AUT-272). Silently no-ops outside Tauri and silently swallows spawn errors — same shape as the other deep-link helpers.

open_settings_screen_recording_js

__screenOpenSettingsScreenRecording() (M-RECP.6 / AUT-272) — shells out to open System Settings → Privacy & Security → Screen Recording. macOS only; Linux/Windows no-op.

request_screen_recording_permission

Async helper: trigger Screen Recording TCC before opening Settings. After tccutil reset ScreenCapture, this call is what makes macOS recreate the app row in the Screen & System Audio Recording list.

request_screen_recording_permission_js

__screenRequestScreenRecordingPermission() — triggers the macOS Screen & System Audio Recording TCC request.

set_system_audio_filter

Async helper: apply a per-app filter.

set_system_audio_filter_js

__screenSetSystemAudioFilter(filter) — returns Promise<void> or rejects with a string error.

start_system_audio_capture

Async helper: start the system-audio session. Returns Ok(()) or Err(message) where the message is the SCK error description.

start_system_audio_js

__screenStartSystemAudio() — returns Promise<void> or rejects with a string error.

stop_system_audio_capture

Async helper: stop the active session.

stop_system_audio_js

__screenStopSystemAudio() — returns Promise<void>.

subscribe_system_audio_level

Subscribe to the system-audio-level Tauri event (M-AUDIO.METER / AUT-287) emitted by the SCK delegate at the stream’s natural buffer rate (~20-100 Hz). Handler receives an EMA-smoothed master-stream RMS in [0.0, ~1.0]. Mirror of crate::mic_ipc::subscribe_mic_level.

system_audio_status

Async helper: status snapshot. true when a session is up.

system_audio_status_js

__screenSystemAudioStatus() — returns Promise<boolean>.
