Your Music, Analyzed by AI
The Songs Library is where you upload and manage the audio files you want to turn into videos. Each uploaded song is automatically analyzed by our AI engine.
Uploading Songs
- Supported formats: MP3, WAV, M4A (up to 75MB per file).
- Drag & Drop: Simply drag audio files into the upload area. They are securely stored via Cloudflare R2.
- Upload Quota: Your storage limit depends on your plan. Check your usage in the top bar.
AI Audio Analysis
After uploading, the CatRender AI engine analyzes each track and extracts:
- Musical Key & BPM: Detected automatically for perfect visual synchronization.
- Genre & Subgenres: AI-classified musical style.
- Mood Tags: Emotional tone of the track (energetic, melancholic, uplifting, etc.).
- Instrumentation: Detected instruments in the mix.
- Lyrics Transcription (Whisper): Optional automatic transcription to SRT subtitle format — ideal for lyric videos.
Managing Your Catalog
You can filter songs by genre, BPM range, key, mood, or lyrics content. Edit metadata inline, export your catalog to CSV, and preview tracks directly in the library.
