Mel-frequency using extractions features

Mel Frequency_wrapping

1. The Mel-frequency warping smooths the high-dimensional magnitude spectrum and transforms it into perceptually meaningful frequencies Mel-scale mimics the sensitivity of the human hearing organ at 1 KHz is perceived stronger as the same shift at 10 kHz The Mel-frequency warping is done using a linear-spaced filterbank in the Mel-domain The transformation is defined by : number of Mel-bands : the weight of the Mel-scale filterbank in band at frequency   Mel-frequency warping
