AB  - Time-Frequency analysis has been in use for more than 20 years and many different Time-Frequency distributions have been developed. Four in particular, Short Time Fourier Transform, Cumulative Spectral Decay, Wavelet and Wigner-Ville have gained popularity and firmly established themselves as useful measurement tools. This paper compares these four popular transforms, explains their trade-offs and discusses how to apply them to analyzing audio devices. Practical examples of loudspeaker impulse responses, loose particles, and Rub & Buzz defects are given as well as a demonstration of their application to common problems with digital/analog audio devices such as Bluetooth headsets, MP3 players and VoIP telephones.
