Examples of 'spectral envelope' in a sentence
Meaning of "spectral envelope"
spectral envelope: In music or sound analysis, spectral envelope refers to the representation of the general shape of the spectral content of a sound signal. It provides information about the distribution of frequencies in a sound and is often used in processes like sound synthesis or audio processing
