Conversation
Audio regions (voiceover / background music) join zoom/annotation as
clip-anchored timeline modifiers: {clipId, sourceStartSec, sourceEndSec}
is the source of truth, startMs/endMs the derived ruler cache, so layers
travel with their clip through reorder/trim (rederiveRegionMs). Assets
gain an "audio" kind — additive, no schema-version bump, and only video
imports claim the primary-asset slot. RegionKind gains "audio"; removal
cascades like every other kind.
DocumentService.addAsset accepts audio files (mp3/wav/m4a/ogg/flac/…) with an explicit caller-side kind hint, so an ambiguous container (a recorded voiceover is .webm, like a screen recording) is filed as audio instead of video. New IPC: open-audio-file-picker (audio filters) and save-recorded-voiceover (writes the MediaRecorder blob under the recordings dir). read-binary-file's approval gate now covers audio extensions so the export post-pass can read layer assets. Removing an asset drops the layers that played it.
Two new lanes (voiceover, music) with drag/resize pills, V/B shortcuts (remappable, advertised by the empty-lane hints), and toolbar buttons that open the add flow: record a voiceover live from the mic (video plays along so you can narrate what you see, auto-stops at the end of the timeline) or import an audio file. The inspector edits volume, mute, start offset, fades and music looping. A headless playback component plays the layers against the timeline clock, synced to the preview. Strings shipped in all 13 locales.
The native pipeline has no extra-audio-track concept, so layers join the CLI's post-export mix path: after exportMultiNative writes the MP4, the editor renders a new audio track (original bed + every layer at its projected export-time position, with gain, offset, fades and looping) via OfflineAudioContext and re-muxes it with mediabunny — video packets copied untouched. Ruler spans are projected onto the assembled (trim-compressed) timeline first; speed regions are deliberately ignored, so a layer plays at 1x under a sped-up stretch (documented v1 limitation). GIF exports are unaffected.
The store's addAsset forwards the caller's kind (audio-layer imports pass "audio") so the renderer and main process agree on what a file is, instead of the main process guessing from the extension.
📝 WalkthroughWalkthroughThe change adds voiceover and music layers to the AI editor. It introduces audio assets and timeline regions, recording and import flows, synchronized playback, inspector and timeline controls, MP4 export mixing, clipboard support, shortcuts, localization, and related tests. ChangesAudio layer support
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to This PR adds microphone recording, persistent audio assets, timeline playback, and MP4 mixing, but the current implementation still has merge-blocking correctness and security risks: recording teardown can leave the microphone active or associate canceled data with a later session, the recording save path accepts unbounded renderer data, and unresolved asset, schema, and export cases can corrupt or silently omit audio.

Inline comments:
In `@electron/ai-edition/document-service.ts`:
- Around line 380-383: Update the deletion logic near withoutAssetClips and
primaryAssetId so it selects the first remaining video asset rather than
assets[0], or undefined when none remain. Preserve primaryAssetId as video-only
and ensure later imports are not blocked by a retained audio asset.
In `@electron/ipc/handlers.ts`:
- Around line 3649-3652: Update the audio file filter in the
dialog.showOpenDialog configuration to remove leading dots from
ALLOWED_IMPORT_AUDIO_EXTENSIONS before assigning the values to
FileFilter.extensions, using extension.slice(1) while preserving the existing
filter name and supported extensions.
In `@src/components/ai-edition/AudioLayersPlayback.tsx`:
- Around line 62-64: Update the looping calculation in the playback position
helper to wrap within the available duration after region.offset, using
sourceDurationSec minus offset as the modulo span. Handle offsets at or beyond
sourceDurationSec without invalid modulo behavior, preserve non-looping
behavior, and add coverage for a nonzero offset with loop enabled.
In `@src/components/ai-edition/ExportDialog.tsx`:
- Around line 376-389: Update the export flow surrounding readBinaryFile and
mixAudioLayersIntoVideo so an unsuccessful or missing completed MP4 read throws
an export error instead of allowing success without audio mixing. Preserve
best-effort handling only for missing individual layer assets, and retain the
existing writeExportToPath error handling.
- Around line 364-373: Update the export logic around layerInputs.push to split
each audio range at every ExportMappingSegment boundary, creating one mixer
input per intersection with mapped start/end times and a source offset advanced
by that intersection’s raw-ruler displacement. Apply fadeInMs and fadeOutMs only
to intersections touching the original range boundaries; intermediate segments
must not retain them. Add an export test covering a layer spanning a middle trim
and verify the resulting inputs preserve the separated source ranges.
In `@src/components/ai-edition/v4/AddAudioLayerDialog.tsx`:
- Around line 180-184: Update AudioLayersPlayback to preserve blob: URLs by
bypassing toFileUrl for them, matching NewEditorShell’s normalization rule
before constructing Audio. Keep existing toFileUrl conversion for non-blob asset
paths.
In `@src/i18n/locales/it/timeline.json`:
- Line 100: Update the Italian timeline locale’s chooseMusic label from “Scegli
file musicale” to the natural wording “Scegli un file musicale” or “Scegli
musica”.
In `@src/lib/ai-edition/schema/index.ts`:
- Line 163: Update assetSchema and schema versioning so persisted version 7
documents retain their previous kind contract: either keep v7 restricted to the
video literal and introduce a new version for audio, or increment the schema
version and explicitly reject incompatible v7 documents. Ensure parsing never
silently treats an audio asset as valid under the existing v7 schema.
In `@src/lib/ai-edition/store/regionClipboard.ts`:
- Around line 14-16: Update pasteRegion to validate copied audio regions before
adding them to doc.audioRanges: reject any snapshot whose assetId is not present
in the destination doc.assets, while preserving valid audio pastes. Add a
cross-project paste test covering an unavailable asset.
In `@src/lib/ai-edition/store/useTimeline.ts`:
- Around line 446-485: Update addAudioRegion to read the current document from
useProjectStore.getState() inside the callback before validating assetId and
constructing the next document, rather than using the stale document captured by
the closure; preserve the existing save and selection behavior and adjust
dependencies only as needed.
- Around line 452-471: Update the audio-region creation flow around
anchorRegionsWithDerivedMs to reject requests when no overlapping clip anchor is
produced, rather than saving the raw region. Ensure unanchored audioRange values
are never persisted; only save an anchored region whose span overlaps a timeline
clip.
In `@src/lib/exporter/voiceoverMix.ts`:
- Around line 258-261: Update the fade-in envelope logic around the layer event
planning so fade-ins whose duration is equal to or longer than the layer span
still produce a ramp ending at endSec instead of leaving the layer silent.
Either schedule the terminal ramp at the layer end or constrain the fade
duration before creating events, and add coverage for fadeInMs >= (endSec -
startSec).
In `@src/native/browserShim.ts`:
- Around line 422-442: Update the browser-shim removeAsset path to filter out
audioRanges whose assetId matches the asset being removed, mirroring the cleanup
behavior in DocumentService while preserving unrelated ranges and assets.

Keep primaryAssetId video-only after deletion.
When an audio asset remains before the primary video, deleting that video assigns assets[0]?.id at Lines 366-369. This persists an audio asset as primaryAssetId. A later video import will also not replace that invalid primary asset.
Select the first remaining video asset, or undefined.
Proposed fix
const primaryAssetId =
doc.project.primaryAssetId === assetId
- ? (assets[0]?.id ?? undefined)
+ ? assets.find((asset) => asset.kind === "video")?.id

🌐 Web query:
For Electron 41.2.1, does dialog.showOpenDialog FileFilter.extensions accept values with leading dots such as ".mp3"?
💡 Result:
No, the extensions array in the FileFilter object for Electron's dialog.showOpenDialog does not accept values with leading dots [1][2][3]. According to official Electron documentation, the extensions array should contain only the extension names themselves without wildcards or leading dots [1][3]. For example, you should use 'mp3' rather than '.mp3' or '*.mp3' [1][3]. Including a leading dot is explicitly noted as incorrect usage [1][2][3].

Pass dotless extensions to dialog.showOpenDialog.
ALLOWED_IMPORT_AUDIO_EXTENSIONS contains values such as ".mp3" and passes them directly to FileFilter.extensions. Electron requires extension names without leading dots, so this filter may omit supported audio files. Map each extension with extension.slice(1).

Split each audio range at export-mapping boundaries.
Lines 366-367 map only the range endpoints. A trim inside a range is non-contiguous. For example, a 0..10 layer with a 4..6 trim becomes one 0..8 input with offset 0, so the mixer plays source audio 0..8 instead of 0..4 followed by 6..10.
Intersect each range with every ExportMappingSegment. Schedule one mixer input per intersection. Advance its source offset by the intersection's raw-ruler displacement. Preserve fades only at the original range boundaries. Add an export test for a layer that spans a middle trim.

Fail the export when the completed MP4 cannot be read.
If readBinaryFile(pickedPath) returns an unsuccessful result, Lines 376-389 skip audio mixing and still report a successful export. The saved MP4 then has no audio layers.
Throw an export error when the completed MP4 cannot be read. Keep the existing best-effort behavior only for missing individual layer assets.

Reject audio snapshots whose assetId is absent from the destination document.
The module-level clipboard survives loadProject. pasteRegion spreads the copied audio region, including assetId, into doc.audioRanges and saves it without checking doc.assets.

Read fresh store state before adding an audio region.
finishWithPath awaits addAsset and then calls the onComplete callback from the render that started the import. This callback reaches an addAudioRegion closure whose document predates the new asset. Line 449 then returns early because that document does not contain assetId.
A normal import or recording can add the asset but never create its audio layer. Read useProjectStore.getState().document inside this callback, as updateAudioRegion and updateAudioSpan already do.

Do not save an audio region without a clip anchor.
When no clip overlaps the requested span, anchorRegionsWithDerivedMs returns the raw region. The audio flow can open with no clips or with the playhead at the timeline end. This saves an unanchored audioRange that cannot follow a clip and can sit outside playable timeline time.
Reject this request, or constrain its span to an overlapping clip before saving it.

Handle fade-ins that consume the full layer span.
If fadeInMs is equal to or longer than the layer span, Line 259 omits the only ramp after Line 258 sets gain to zero. The layer then exports as silence.
Generate a ramp that ends at endSec, or constrain the fade duration before planning the envelope. Add a case for fadeInMs >= (endSec - startSec).

Remove browser-shim audio ranges with their assets.
After browser mode saves an audio layer, removeAsset retains audioRanges that reference the deleted asset. The document then persists a dangling layer while playback skips it because its asset path no longer exists.
Filter audio ranges by assetId in the browser-shim removal path, as electron/ai-edition/document-service.ts does.

- A non-looping layer whose file runs out before its span now holds silent instead of replaying its head in a 60 Hz restart loop, and a looping layer folds over the post-offset window so it stays in phase with the export mix. - The music dialog's auto-import is guarded against re-firing on parent re-renders (inline onComplete churns on every playhead tick), which re-opened the native picker and could add duplicate layers. - Inspector slider drafts follow external region edits (undo/redo). - The export says so instead of silently dropping layers when a layer file or the exported file cannot be read back for the mix.

Do not mark valid looping playback as exhausted.
When region.loop is true and its offset is within sourceDuration, layerSourcePosition wraps target through the valid source range. The exhausted check still pauses the element during the final 30 ms of each loop, which can drop audio until the next tick.
Limit exhausted to non-looping regions and looping regions whose offset is at or beyond the source duration. Add a regression test in src/components/ai-edition/AudioLayersPlayback.test.ts.

Count unresolved audio asset references before filtering.
audioRegionSchema does not require assetId to match an entry in assets. The browser shim's removeAsset removes only the asset, so it can leave orphaned audioRanges. ExportDialog.tsx filters these ranges out before missingLayerFiles is incremented, which omits audio without a warning. Count unresolved references before filtering, or handle missing assets in the loop.

Prevent a cancelled music picker from reopening after a parent rerender.
When openAudioFilePicker returns without a file, importFile clears pickerOpenRef.current and leaves the dialog open. A later NewEditorShell rerender recreates the inline onComplete, which recreates importFile and reruns the auto-open effect. The effect can then open a second native picker.
Track whether the picker auto-opened during the current open session. Reset that state only when the dialog closes. Keep manual picker retries available. Add a same-package interaction test for cancellation, parent rerender, and no second picker.

Thanks for this — it is a lot of careful work, and the recording flow especially. I have to open with the awkward part, though, and I would rather say it now than after you have put more into it.
This overlaps #502, which has been open since before this one and has already been through review. 78 of your 88 files are also touched there. Both add kind: "audio" assets, an audio lane, preview playback and export mixing. Only one can land, and I am keeping #502 as the base — it came first, and its export path is in the right place (see below).
But your positioning model is the better one, and I would like to keep it. #502 places audio at an absolute raw-timeline second; yours anchors a region to its clip, so it travels through reorder, trim and delete instead of sitting still while the content slides underneath. That is the part worth salvaging, and it is cheap: the anchor machinery is already on main and already generic over {id, startMs, endMs} — anchorRawRegionsToClips, anchorRegionsWithDerivedMs, coalesceRegionsForRuler, patchPillById, replacePillSpan in timeline/timelineMap.ts, plus rederiveAnchoredRegion and mapAllRegionCollections in document/timeline.ts. Your whole integration is about fifteen lines: the ...clipAnchorShape spread in audioRegionSchema, an audioRanges branch in mapAllRegionCollections, and the RegionKind / removeRegion cases.
So the ask is to pivot rather than to close: rebase onto #502 and bring the anchoring across, keeping #502's document shape and its native mixer. Concretely that is audioTrackSchema restated as {startMs, endMs, ...clipAnchorShape, offsetMs, gainDb, …}, the audioTracks branch added to mapAllRegionCollections, most of #502's hand-rolled array helpers in document/audioTracks.ts deleted in favour of the pill helpers, and its per-track lane replaced by coalesceRegionsForRuler pills. Roughly 400-600 lines across five files — far less than either PR, since almost none of your 2500 is the anchor model.
Two things I want to be straight about, because they cut against the pivot as much as for it.
First, I had assumed the anchor model would fix the three bugs review found in #502 — a preview/export desync across trims, speed regions retiming audio only in the preview, and an export projection that disagrees with resolveVisibleClips. I checked each against your code and it fixes none of them; all three are reproduced here, the last one in a third copy of resolvePlaybackSegments living in src/lib/exporter/. The anchor decides where the pill sits, not how the media inside it advances. So the pivot is worth doing for reorder/trim survival, not because it clears the existing bugs — those still need fixing on top, ideally by deriving the mapping from resolveVisibleClips instead of a private copy.
Second, the anchor model brings a problem of its own that neither PR has solved, and it is the piece to budget for — see the comment on schema/index.ts.
I am also flagging the export path: I would keep #502's native mixing rather than the post-export re-render and re-mux here, for the memory, cancellation and failure-reporting reasons in the ExportDialog.tsx comment.
Happy to talk it through before you touch anything — and sorry the duplication was not caught earlier, that is on us for not flagging #502 more visibly.
On lines outside the diff:
electron/ai-edition/document-service.ts:366 — addAsset is correctly guarded so an audio import never claims the primary slot, but removeAsset still does primaryAssetId = assets[0]?.id with no kind filter.
Import music, then delete the only video asset, and primaryAssetId points at an mp3 — after which ExportDialog's primaryAsset, the aspect-ratio picker and the "add a video before exporting" guard all read an audio file as a video, and buildSceneDescription gets a screenPath with no video stream.
Same predicate as the add path fixes it: assets.find(a => a.kind === "video")?.id.

A recorded voiceover lands one full take-length to the right of where it was recorded.
handleVoiceoverRecordingStart starts playback when recording begins, so currentTimeSec advances for the whole take. When it stops, handleAudioLayerReady calls addAudioRegion, which reads playheadSec() live — by then the playhead has moved by the take duration.
Park at 0:00, record 10s of narration: the region is created at 0:10-0:20. Every recorded voiceover is misplaced by its own length, so the headline gesture needs the pill dragged back by hand every time. The playhead at record start wants capturing in openAudioLayerFlow (which already computes maxDurationSec there) and threading through.

This is the structural cost of the anchor model on continuous media, and the part nobody has written yet.
anchorRawRegionsToClips ventilates a span into per-clip fragments and copies the payload verbatim, so a music layer at raw [5s,15s] with offsetMs: 2000 and 500ms fades becomes two regions that each start the source at 2s and each fade in and out. Export emits one AudioLayerMixInput per region and the preview mounts one <audio> per region, so a bed spanning a cut audibly restarts and dips at every boundary.
The anchor model was built for value-per-span effects, where splitting is semantically neutral; media is not. Each fragment needs its offsetMs advanced by the elapsed source time, or a coalesce step before render. Worth noting this is easier on #502's native mixer — it already takes {path, startSec, gainDb, trimStartSec, trimEndSec} per entry, so an advanced trimStartSec per fragment falls straight out.

This is why I would keep #502's native mixing rather than the post-export pass.
After a successful native export the renderer reads the whole MP4 back through IPC, blobs it, takes a second arrayBuffer() copy, decodeAudioDatas the entire file, renders an OfflineAudioContext buffer (~230MB for 10 minutes at 48kHz stereo), decodes each layer's source once per fragment, and holds the remuxed output in a BufferTarget before a final copy back through IPC. A 30-minute 1080p export is multi-GB peak in the renderer.
Three behaviours around it worry me more than the memory:
cancelRefis never consulted in this block andhandleCloserefuses to close duringwriting, so a long mix cannot be aborted.progressis frozen at the last render value for the whole pass, so it looks hung.- If
mixAudioLayersIntoVideothrows, the catch reports "Export failed" even though the native export already wrote a complete file topickedPath. And ifreadBinaryFile(pickedPath)returns!successthe whole block is skipped silently and the export is reported as a success with no layers and no warning.

buildExportTimelineMapping walks document.timeline.clips unfiltered, but the exported programme is resolveVisibleClips(document), which additionally drops clips whose asset has no resolvable originalPath.
So a project with one relinked-away asset renders N-1 clips while the mapping counts N, and every layer after the missing clip is late by that clip's full duration. The unprobed-clip branch diverges too: this falls back to clip.sourceEndSec ?? clip.sourceStartSec, while buildNativeClipList uses resolveClipSourceEndSec with its probe/duration/guess precedence.
It is also a near-line-for-line reimplementation of resolvePlaybackSegments (document/timeline.ts:163), which makes it the third copy of that projection in the tree — main has the original, #502 added projectRawTimelineSecToPlayback, this adds a fourth clock in the exporter package. Whichever PR lands, deriving the audio mapping from resolveVisibleClips rather than alongside it is about five lines and removes the class.

planLayerGain's final event {atSec: endSec, value: 0} carries no ramp, so renderLayeredAudio calls setValueAtTime(0, endSec) — an instantaneous step. The preceding ramp event only re-asserts the value the gain already holds, so fadeOutMs produces a hard cut in the exported mix while the preview (layerVolumeAt) does ramp down.
voiceoverMix.test.ts:82 asserts exactly this event list, so the test currently locks the behaviour in.
Same function: if fadeInMs is at least the layer span, the startSec + fadeInSec < endSec guard skips the ramp-up entirely and the gain stays at 0 — a 0.5s layer with a 1s fade-in exports silent.

Two things in the music flow.
The auto-open effect depends on busy, and on the import-failure path onComplete is never called, so open stays true while busy flips back to false — the effect re-runs and re-opens the OS picker immediately. As long as the import keeps failing that is an unclosable loop.
Separately, the [open] cleanup stops the MediaStream tracks and nulls recorderRef but never calls recorder.stop(). If the dialog unmounts mid-recording (project close, shell teardown) the take is never flushed, onRecordingStop never fires, and the video element is left playing.

Summary
Adds two new audio layer kinds to the editor: voiceover and background music. A layer is a clip-anchored timeline region (same v5 anchor model as zoom/annotation, so it travels with its clip through reorder/trim) that plays an audio asset at its position on the timeline — audible in the preview and mixed into MP4 exports.
How a layer gets in:
Both kinds get their own lane on the timeline (green/amber pills) with the same drag/resize/select/copy/paste/delete affordances as every other lane, and a new inspector pane: volume (−60…+12 dB), mute, start offset, fade in/out, and looping for music.
Audio assets are first-class in the document (
kind: "audio", additive — no schema-version bump) and never claim the primary-asset slot.Export: the native pipeline has no extra-audio-track concept, so layers join the existing post-export mix path (
voiceoverMix.ts, previously CLI-only): after the native export, the renderer re-renders the audio track (original bed + every layer, with gain/offset/fades/looping) viaOfflineAudioContextand re-muxes with mediabunny — video packets copied untouched. GIF exports are unaffected.Known v1 limitation (documented in code): speed regions are ignored when positioning layers, so a layer plays at 1× under a sped-up stretch.

Not captured yet — two new lanes (voiceover / music) sit below the existing five lanes on the timeline; the add-flow dialog offers Record voiceover / Import audio file (music goes straight to the file picker).
