Examples of 'spectral coefficients' in a sentence
Meaning of "spectral coefficients"
The term 'spectral coefficients' is commonly used in the field of signal processing and audio analysis. It refers to the numerical values that represent the amplitude or magnitude of individual frequency components present in a signal or waveform. Spectral coefficients are often obtained through mathematical algorithms or Fourier transforms and are used to analyze and manipulate audio signals
