Spectrum

One of the types of objects in Praat. A Spectrum object represents the complex spectrum as a function of frequency. If the spectrum was created from a sound (which is expressed in units of Pascal), the complex values are expressed in units Pa/Hz (Pascal per Hertz). For detailed information, see Sound: To Spectrum....
