Peak Detection (Steps 3 and 4) Due to the sampled nature of spectra obtained using the STFT, each peak (location and height) found by finding the maximum-magnitude frequency bin is only accurate to within half a bin. A bin represents a frequency interval of Hz, where is the FFT size. Zero-padding increases the number of FFT bins per Hz and thus increases the accuracy of the …

The peaks detection procedure is an integral part of various signal analysis algorithms. For example in [ 14] an approach to detection of impulse noise in audio signals is presented. The proposed technique uses adaptive thresholding which can be obtained by averaging the detection function and scaling it.

The current algorithm is pretty simple it basically looks for a number of consecutive signal samples which are bigger than the previous, if not the increments the "fall" counter, when the fall counter is a given number (8 by now) is the peak is saved to a array.

Robust peak detection algorithm (using z-scores) I came up with an algorithm that works very well for these types of datasets. It is based on the principle of dispersion: if a new datapoint is a given x number of standard deviations away from some moving mean, the algorithm signals (also called z-score).The algorithm is very robust because it constructs a separate moving mean and …

Filtered audio data are divided into windows of samples (whose dimension is the sample frequency, i.e. 1s). A peak detection algorithm is applied to each window and identifies as peaks all values above a certain threshold (defined as C ⋅ a v g ( w i n d o w) where C is for the user to be configured, e.g. 0.95 ).

New peak detection algorithm from Scipy since version 0.11.0. Its usage is really trivial, but it misses out of the box filtering capacities. It includes an order parameter that can serve as a kind of minimum distance filter. The filtering behavior is customizable through the comparator parameter, which

PEAK DETECTION ALGORITHM Problem posing Assume the signals curve {Xi }(i=1,2,...m) is assembled with n consecutive peaks/troughs. The minimum width of peak / trough is β. Target: find out distribution of peaks/troughs number, height and width. Obviously peak point must be local maximum, and trough point must be local minimum.
