Module system_audio_picker 

<SystemAudioPicker /> — live-data picker for the speaker / per-app audio capture in the Recorder surface (M-AUDIO-SYS.2 / AUT-279 / AUT-282).

Mirrors crate::mic_picker for the speaker path with two key differences:

• Master on/off toggle (enabled signal) gates everything. The mic picker has no master toggle because a mic device is always selectable; system audio is opt-in and the toggle is the cleanest UX.
• Multi-select with bundle-id persistence. Each app row has a checkbox; the selected bundle ids round-trip through LocalStorage so a Spotify selection survives across launches.

Ships the full picker: filter chips (All / None / Suggested / Custom) with the suggested-app heuristic, a 250 ms debounced filter-apply, real app icons (AUT-288 — inline PNG data: URLs from the backend, glyph fallback), and the SCK-denial settings deep-link.

Structs

SystemAudioBodyProps 🔒

Props for the SystemAudioBody component.

Enums

ActiveChip 🔒

Which filter-chip is visually active given the current picker state. Custom is the implicit “user hand-edited the checkboxes” mode — no chip is mapped to it as a click target; it just lights up when none of the other three describe the current selection.

Constants

SUGGESTED_BUNDLE_PREFIXES 🔒

Suggested-app heuristic (M-AUDIO-SYS.3 / AUT-288). Best-effort baseline list of bundle-id prefixes the recorder thinks the user probably wants when they click the “Suggested” chip: browsers, media / streaming apps, and comm apps. Excludes system services + the recorder itself by omission.

Functions

SystemAudioBody 🔒

Required Props

SystemAudioPicker

<SystemAudioPicker /> — master toggle + expandable per-app checklist.

apply_filter_from_selection 🔒

Build a filter from the current selection and push it to the backend. Empty selection → AllAudio (capture everything); non-empty → OnlyApps (capture just those).

base64_encode 🔒

Standard base64 (RFC 4648) of input. Tiny + pure (no dep) so it runs in the native unit tests as well as wasm — used to inline the app-icon PNG (AUT-288) as a data: URL.

compute_active_chip 🔒

Compute which chip should appear active. Order matters — when multiple chips could describe the state (e.g. empty selection could be “All” OR “Suggested produced no matches”), the most specific wins.

icon_data_url 🔒

A data:image/png;base64,… URL for the app icon (AUT-288), or None when no icon was captured (empty bytes — the row then shows its glyph). The backend ships native-size PNGs; None is the headless / no-icon path.

read_enabled 🔒

read_selected_ids 🔒

render_app_row 🔒

same_set 🔒

Order-insensitive equality of two bundle-id lists.

schedule_filter_apply 🔒

suggested_bundle_ids 🔒

Walk the running-app list and pull out bundle ids whose prefix is in SUGGESTED_BUNDLE_PREFIXES.

summary_label 🔒

write_enabled 🔒

write_selected_ids 🔒
