Audio Compression

  • Adaptive LPC with Levinson-Durbin
  • Rice/Golomb entropy coding
  • Mid-side stereo encoding
  • Perfect lossless roundtrip verified

Semantic Compression

  • Understands data structure
  • Recursive pattern detection
  • Adaptive context modeling
  • Format-aware encoding

All benchmarks verified with perfect lossless roundtrip. Audio tests include synthetic waveforms and real music (full-length songs).
