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. اغاني رومانسيه تامر حسني 2021
