Abstract :
A new method of obtaining audio power spectra is described. Advantages of the new method are speed of use and great frequency detail. The new method is based on the production of a "composite signal" which has a time continuous power spectrum. The composite signal method can be used with many types of signals such as speech, music, traffic noise, et cetera.
