Import tracks into the library.

MP3, WAV, FLAC, OGG via drag-and-drop. Hypnotika analyzes BPM and key automatically.

1 · Drag-and-drop or file picker

  • Drag-and-drop: drag audio files from File Explorer directly into the library window. Multiple at once.
  • + Add button (top right): opens file picker. Multi-select with Ctrl+click or Shift+click.

2 · Supported formats

  • MP3 (most common, smallest files) — ≥192 kbps recommended for hypnosis sessions
  • WAV (uncompressed, highest quality)
  • FLAC (lossless compressed)
  • OGG Vorbis and M4A (AAC)

3 · What happens at import

  1. File copied to %APPDATA%\Hypnotika TranceDeck\tracks\ — your original on disk stays untouched
  2. Audio decoded (Web Audio API)
  3. BPM detection: 30-60 sec analysis
  4. Key detection via Essentia.js (KeyExtractor) — uses 60 sec from the track middle
  5. Track appears in library with detected values

Nature sounds intentionally do not get BPM/key analysis — waves, wind, birds have no meaningful values.

4 · Re-analyze

If detection fails or is inaccurate (e.g. BPM on very slow tracks <60): hit „Reanalyze" button at top of library. Goes through all tracks without BPM/key and tries again. ~2-5 sec per track.

5 · Tagging

Per track in the tags column: select which phases this track is allowed in — Intro / Middle / Climax / Outro. Multiple tags per track allowed. Untagged tracks are never picked for phases.
