Mel spectrograms

Description

The mel scale is a perceptual scale of pitches judged by listeners to be equal in distance from one another.

A Mel Spectrogram makes two important changes relative to a regular spectrogram that plots Frequency vs Time.

• it uses the mel scale instead of Frequency on the y-axis.
• it uses the decibel scale instead of Amplitude to indicate colors.

The spectrograms can then be processed with SOTA computer vision models.
