 ## 🔴 High Priority — Core editing gaps
 
-- [x] **Cut / Mute sections** — select a time range and choose to cut (remove entirely) or mute (silence audio while video continues). Cut sections show as red overlays, mute sections as transparent blue overlays on the timeline over the transcript text and audio waveform. Backend: `ffmpeg -af volume=0` for mute, time-based cutting for removal.

-- [x] **Silence / pause trimmer (in progress)** — detect pauses using min duration (ms) + amplitude threshold (dB), then apply detected pauses as cut ranges. Initial endpoint: `/audio/detect-silence`; UI includes filter controls and an "Apply As Cuts" action.

-- [x] **Grouped silence-trim zones (editable batch)** — when pauses are applied, tag them as a batch (`trim_group_id`) so the user can: (1) delete all zones from that auto-trim pass at once, and (2) still select/resize/delete individual zones independently.

-- [x] **Edit silence-trim group settings after apply** — allow reopening a trim group and changing its detection settings (min pause ms, threshold dB, pre/post buffers), then reapplying updates to that group without affecting unrelated edits.

-- [ ] **Cut preview** — before committing a delete, play what the audio will sound like with that section removed (pre-listen across the edit point). Pure frontend using Web Audio API — splice the AudioBuffer and play the join.

 ## 🟡 Medium Priority — Widely expected features
 
-- [ ] **Transcript search (Ctrl+F)** — find words/phrases in the transcript and highlight matches. Pure frontend. Critical for long-form content. Jump between matches with Enter.

-- [ ] **Mark In / Out + delete (I / O keys)** — keyboard shortcuts to mark a time range on the timeline, then delete it. Faster than click-dragging words. Store the in/out points in state, `Delete` removes them.

-- [ ] **Low-confidence word highlighting** — WhisperX already returns `confidence` per word. Words below a threshold (e.g. < 0.6) should be visually underlined or tinted so the user knows where to double-check.

 ## 🟢 Lower Priority — Differentiating / power features
 
-- [ ] **Audio normalization / loudness targeting** — single "Normalize" button that targets a LUFS level (-14 for YouTube, -16 for Spotify). Backend: `ffmpeg -af loudnorm`. Very high value for podcasters, ~2–3 hours of work.

-- [ ] **Background music track** — a second audio track for background music with volume ducking. Major gap in Descript that TalkEdit could own. Backend: `ffmpeg` amix + `asendcmd` for auto-ducking.
