Criteria
Compression Ratio (CR): compressed file size / original uncompressed file size (lower the better)
Spectrogram Error: direct difference between power spectrograms (lower the better)
Weighted Spectrogram Error: direct difference between A-weighted power spectrograms (lower the better)
Signal-to-Noise Ratio (SNR): noise is calculated from signal power difference (higher the better)
Weighted SNR: noise is calculated from A-weighted signal power difference (higher the better)
