Note on measures for spectral flatness
WebSpectral flatness (or tonality coefficient) is a measure to quantify how much noise-like a sound is, as opposed to being tone-like 1. A high spectral flatness (closer to 1.0) indicates … WebAbstract: The Szegö-Kolmogorov-Krein theorem is the natural basis for the spectral flatness measure commonly advocated in linear predictive speech processing and parametric spectrum analysis. From this theorem it follows that the logarithm of any normalized spectrum averages to zero.

WebSpectral Flatness Measure (SFM) Spectral flatness [6] or tonality coefficient is the ratio of geometric mean to the arithmetic mean of the power spectrum. Arithmetic mean is … WebThe ripple in the spectral flatness measurement is due to downsampling to baseband. Try using a different filter or changing the stop-band attenuation and observe the impact on the spectral flatness. For meaningful EVM results generate at least 20 EHT MU packets as specified in Section 36.3.19.4.4 of [ 1 ]. References

SFM is a well -known and accepted method for evaluation of the “compressibility” of a process. Using this equality we estimate the MIR from the spectral flatness measure as the log (SFM). C. Properties of SFM for Linear Processes
WebSpectral Flatness Measure (SFM) Spectral flatness [6] or tonality coefficient is the ratio of geometric mean to the arithmetic mean of the power spectrum. Arithmetic mean is average or mean of ‘N’ sequences whereas geometric mean is Nth root of their products. Therefore SFM is given as: where x(n) is magnitude of bin number ‘n’.
