Statistical properties of music signals at different speeds of playing instruments

The paper presents analyzed statistical properties of music signals from various instruments playing at different speeds. The signals are contained in about an hour of music recorded in the form of ten sequences. The analyzed signals are obtained from five different speeds of playing music for each sequence. For each playing speed time variation of the signal level was found, performed with a 10 ms period of integration in rms calculation and with 70% overlap, statistical and cumulative distributions of signal level, skewness and kurtosis, the parameters L₁, L₅, L₅₀, L₉₅ and L₉₉, which are derived from cumulative distributions as numerical indicators of dynamic properties. The paper contains detailed statistical data for all five-speed playing.
