Evaluation of Mel-Band and MFCC-Based Error Metrics for Correspondence to Discrimination of Spectrally Altered Musical Instrument Sounds
An objective measure of the subjective timbral difference between two musical sounds is a difficult problem. Mel-band-based metrics and single mel-frequency ceptral coefficient were considered as a way of improving results obtained from previous methods based on harmonic and critical-band error metrics. Results indicate that timbral discrimination is determined by the first 5 to 10 harmonics rather than the broad spectral envelope. More sophisticated methods do not offer significant advantage.
