Agg Entropy

Aggregate Entropy

The aggregate entropy measures the disorder (Bits) in a sound by analyzing the energy. Higher values correspond to greater disorder in the signal whereas a pure tone have zero entropy. It corresponds to the overall disorder in the sound.in a sound by analyzing the energy. Higher values correspond to greater disorder in the signal whereas a pure tone have zero entropy. It corresponds to the overall disorder in the sound

Avg Entropy

Average Entropy

The average entropy measures the average disorder in a sound. Describes the amount of disorder for a typical spectrum within the signal

Max Entropy

Maximum Entropy

This entropy is calculated by finding the entropy for each frame in the signal and then taking the maximum values
