Spectrum: To Sound

A command for creating a Sound object from every selected Spectrum object.

Mathematical procedure

The reverse of the Fourier transform described in Sound: To Spectrum.... If the Spectrum is expressed in Pa/Hz, the Sound will be in Pascal. The frequency integral over the Sound equals the time integral over the Spectrum.


If you perform this command on a Spectrum object that was created earlier with Sound: To Spectrum..., the resulting Sound is equal to the Sound that was input to Sound: To Spectrum....
