Classification and Comparison of Real vs. Test Audio Signals
Audio test signals have long been used in reliability testing for loudspeakers and other parts of the audio reproduction chain. Several characteristics may be easily obtained from an audio signal in the digital domain including frequency content, word code histograms, and several different statistical values such as mean, skewness, kurtosis, and crest factor. The crest factor will be examined as a function of time for non-periodic signals. This collection of metrics will be examined to determine whether certain groupings occur, and the test signals will be examined to see if they encompass the greatest amount of qualities of real world signals as possible. Optimal metrics for a loudspeaker test signal are suggested.
