Version History

A record of what’s changed in each version of PassThru.

v1.4.8 latest March 31, 2026

Added

Per-source Apply Processing toggle on each audio source in Sources — enable or disable echo cancellation, noise suppression, and auto gain control independently for Primary and Secondary audio
Secondary audio now defaults to processing off, which is the correct default for system audio and capture card sources

Fixed

Disabling processing now explicitly sets all processing flags to false rather than omitting them, preventing the browser from silently re-applying its own defaults and causing choppy or distorted audio
New profile buttons in Manage Profiles did nothing — prompt() is blocked in Electron's renderer; replaced with an inline name input that appears below the buttons

Changed

New from Current and New from Defaults buttons now share the row equally at 50% width each

v1.4.7 March 29, 2026

Added

Named settings profiles — create multiple profiles (e.g. Camera, Screen, Podcast) and switch between them from the title bar without opening Settings
Profile quick-switcher in the title bar: click the profile button to see all profiles and switch instantly; the active profile is highlighted and the default is marked with a star
Manage Profiles panel: rename, delete, set default, or create new profiles from current settings or factory defaults
Settings are now stored in a structured JSON file (settings.json in the app data folder) rather than browser local storage, making them portable and inspectable
Dirty-close protection — if you close the app with unapplied changes the app offers to Save & Close, Discard & Close, or Cancel

Changed

All settings changes are written to disk immediately on Apply, removing the need for a separate save step
Export and import now operate on the active profile's data directly rather than individual localStorage keys
Session Persistence section updated to reflect file-based storage

v1.4.5 March 13, 2026

Added

Audio test toggle for both Primary and Secondary audio sources — click Test to open an inline level meter for that device, click Stop to close it. Both sources can be tested independently before applying settings.
Viewfinder Done now auto-starts the stream when no stream is active, so first-time region setup completes in one step without needing to hit Apply separately
Status message "Region set — Streaming" shown after viewfinder Done auto-starts to confirm the stream is live
Recording save feedback — the timer area briefly shows "Saved" on success or "Save failed" on error after stopping a recording

Changed

Audio level meter removed from the Sources tab; replaced by per-device Test buttons so primary and secondary sources are tested the same way
Changing the selected audio device automatically stops any active test for that slot so the meter doesn't show stale signal
Resize handler debounced — display settings no longer recalculate on every pixel of window resize

Fixed

Recorded chunks are now cleared at the start of save rather than after the async write, freeing memory sooner for long recordings

v1.4.4 March 8, 2026

Added

Viewfinder region selection: the PassThru window itself becomes the region selector — reposition and resize the window to frame the capture area, no separate overlay needed
Select Region tile in the screen sources grid (Settings > Sources) for entering viewfinder mode
Secondary audio source: mix a second audio device (e.g. a system monitor) alongside the primary mic in a single recording track (Settings > Sources > Audio)
Audio device dropdown now labels PulseAudio/PipeWire monitor sources as (System Monitor) for easy identification on Linux
Resolution and frame rate dropdowns label the highest supported option as (Source Max) when a camera device is selected

Changed

Region selection replaced: old fullscreen drag-to-select overlay removed in favour of the viewfinder window approach
Crop region shortcut removed from Settings > Shortcuts; region selection is now accessed from the Sources tab
System sounds toggle removed; replaced by the Secondary Audio dropdown which works on all platforms including Linux
Dotted viewfinder border remains visible while recording but is excluded from the output via a 2 px inset crop
Title bar and controls bar stay visible (no auto-hide) while in viewfinder mode

Fixed

Region recording now captures the correct monitor when the PassThru window is on a non-primary display
Recording correctly crops to the region inside the dotted border rather than the full screen

v1.4.0 March 4, 2026

Added

Capture region crop for screen capture only: fullscreen overlay on the selected display so you can drag to select any area. Set a keybind in Settings > Shortcuts (no default); works while streaming or recording.
Include system sounds option for window/screen capture (Settings > Sources > Audio)
Recording and clip video quality setting: High, Medium, or Low for smaller files (Settings > Advanced > Recording)
Stereo as the default audio channel mode

Changed

PassThru is excluded from the window capture list so it doesn't appear when choosing a window to capture
Capture region / crop is available only for screen capture; window capture always shows the full window
Screen crop is shortcut-only (no default keybind; user sets one in Shortcuts)
Crop region is session-only: not saved between launches and not included in settings export/import

Fixed

Window/screen capture now recovers when the captured window is closed: stale source is cleared and you can pick the window again from Settings
Placeholder buttons (Open Settings, Restore Session) were unclickable on launch; fixed by allowing clicks to pass through the video crop wrapper when no stream is active
Non-primary display (e.g. second monitor) now works on first selection; capturer warmup and retries avoid needing to select the main monitor first
Screen crop region now displays correctly on stream (including when changing the selection multiple times)

v1.3.6 February 21, 2026

Added

Real-time stats overlay showing FPS, latency, dropped frames, resolution, and audio info
Configurable overlay corner position (Top Left, Top Right, Bottom Left, Bottom Right)
Stats overlay slides toward the edge when the title bar or controls bar auto-hides
Toggle Stats keyboard shortcut (configurable in Settings > Shortcuts)

Changed

Fixed

FPS counter was reporting the display refresh rate instead of the source delivery rate
Dropped frames calculation now compares against the configured frame rate
App icon not appearing in packaged builds due to ASAR path issue

v0.3.0 February 15, 2026
