How Audio Compression Works
Audio compression uses sophisticated algorithms to reduce file size. Here's what happens behind the scenes:
- Analysis: The audio is analyzed to identify redundant or imperceptible data.
- Psychoacoustic Modeling: Our algorithms use knowledge of human hearing to remove sounds you can't perceive.
- Bitrate Optimization: The audio is re-encoded at an optimal bitrate based on your chosen compression level.
- Quality Verification: The output is verified to ensure acceptable quality standards are met.
