🔧 Optimizations for Large Files The system automatically handles large files using these techniques:

Diagram Code

Chunk Processing:

Audio is split into 1-minute segments

Only segments >10 seconds are processed

Enables parallel processing (future implementation)

Early Stopping:

Stops processing when 3 consecutive chunks agree with high confidence

Saves processing time for long files

Efficient Extraction:

Uses FFmpeg for fast audio extraction

Torchaudio fallback for compatibility

Direct streaming for URL sources

Confidence Threshold:

Only predictions >60% confidence are considered

Reduces false positives from noisy segments
