웹2024년 2월 16일 · Mel Scale. Before discussing Mel Spectrograms, we first need to understand what the Mel Scale is and why it is useful. The Mel Scale is a logarithmic transformation of a signal’s frequency. The core idea of this transformation is that sounds of equal distance on the Mel Scale are perceived to be of equal distance to humans. 웹2024년 6월 18일 · Mel、Bark以及ERB介绍，概述 人耳对声音的敏感度随频率的变化而变化，且敏感度与频率之间并不是简单的线性正比关系，而是近似成对数关系。为了更好的逼近人耳的拾音特点，通常将频率进行非线性变换到Mel刻度（或者Bark刻度或者ERB刻度），然后将上述刻度均匀分成等距的M段，然后再反变换到频域。
