64QAMRayleigh

说明：  画n角星,其中n为大于5的奇数(偶数可以看成两个奇数角星的叠加) 比如6角星,可以看成两个三角星的叠加(Plotting and filling n-pointed star, in which n is an odd number greater than 5)

Chroma Feature Analysis and Synthesis Chroma features are an interesting and powerful representation for music audio in which the entire spectrum is projected onto 12 bins representing the 12 distinct semitones (or chroma) of the musical octave. Since, in music, notes exactly one octave apart are perceived as particularly similar, knowing the distribution of chroma even without the absolute frequency (i.e. the original octave) can give useful musical information about the audio and may even reveal perceived musical similarity that is not apparent in the original spectra.
