What is another word for power spectrum subtraction?
Pronunciation: [pˈa͡ʊə spˈɛktɹəm sʌbtɹˈakʃən] (IPA) 
Power spectrum subtraction is a signal processing technique used in various fields such as audio processing, medical imaging, and astrophysics. In signal processing, it refers to the subtraction of the power spectrum of a noise signal from that of a signal of interest. Some synonyms for power spectrum subtraction include noise reduction, spectral subtraction, and noise cancellation. In audio processing, it may also be called spectral gating or frequency domain gating. This technique is helpful in removing unwanted noise from audio recordings, enhancing signal-to-noise ratio in medical images, and studying the properties of astronomical objects. Overall, power spectrum subtraction is a valuable tool for improving the quality of signals in various disciplines.
