A voice signal oscillates slowly - for example, a 100 Hz signal will cross zero 100 per second - whereas an unvoiced fricative can have 3000 zero crossing per second. To calculate of the zero-crossing rate of a signal you need to compare the sign of each pair of consecutive samples. In other words, for a length N signal you need O(N) operations. Such …

librosa.feature.zero_crossing_rate. Compute the zero-crossing rate of an audio time series. If True, frames are centered by padding the edges of y . This is similar to the padding in librosa.stft , but uses edge-value copies instead of reflection. By default, the pad parameter is set to False, which differs from the default specified by librosa ...

a signal. Zero-crossing rate is a measure of number of times in a given time interval/frame that the amplitude of the speech signals passes through a value of zero, Fig 1. Speech signals are broadband signals and interpretation of average zero-crossing rate is therefore much less precise However, rough estimates of spectral properties can be obtained using a representation based …

Zero-Crossing Rate. As the name suggests zero-crossing rate is the measure of the rate at which the signal is going through the zeroth line more formally signal is changing positive to negative or vice versa. Mathematically it can be measured as . …
