Complete Feature Set

Users can now:

  • See all identified ad segments before audio editing
  • Approve, reject, or modify segment times
  • Add manual segments the LLM missed (false negatives)
  • Delete segments incorrectly identified (false positives)
  • View full transcript with timestamps and labels
  • Preview merged ranges that will be removed
  • Use waveform visualization with draggable regions
  • See real-time updates to merged removal ranges

Workflow

Download → Transcribe → Classify → Review → Edit Audio → Done

                                Manual correction
                                   possible here

Outstanding Items

  1. Testing: Integration tests for review workflow
  2. Testing: Test with various podcast types in production
  3. Testing: Fix test database schema issue
    • 6/12 tests in test_segment_manager.py fail with "no such column: post.segments_approved"
    • Issue: ProcessingJob table missing segments_approved column in test database
    • All models imported in conftest.py, but db.create_all() not creating all columns
    • Passing tests: test_merge_contiguous_segments_* (don't use database)
    • Failing tests: test_apply_overrides_*, test_uses_overrides_*, test_falls_back_*, test_returns_segments_*
    • Note: Beartype mock issue already resolved (added spec=Session to mock_db_session)
  4. Polish: Mobile-responsive review UI
  5. Enhancement: Preview audio playback before approval

Technical Considerations

  • Segment data fetched on-demand, could be cachedIMPLEMENTED
    • Added TTL-based caching (5min default) for segment data
    • Fixed N+1 query in _get_all_transcript_segments (now uses single query with IN clause)
    • Automatic cache invalidation on segment updates
    • New file: src/podcast_processor/cache_utils.py
  • Waveform generation is client-side (CPU intensive for long episodes)
  • Mobile UX may benefit from simplified list view
  • Consider websocket for real-time status updates during review
