&dhucpackage; &dhsection; &dhpackage; a command line tool to extract pitch candidates from sound files. &dhpackage; [options] -i soundfile DESCRIPTION &dhpackage; attempts to extract fundamental frequency in sound files. When no pitch candidate is found, the output is 0. Five fundamental frequency extraction methods are available. Results can be printed in Hertz or in MIDI pitch. A plotting module is available via the Gnuplot Python package. OPTIONS This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. input sound file pitch detection mode [default=mcomb] mcomb|yin|fcomb|schmitt output pitch in units [default=Hz] freq|midi|cent|bin buffer size [default=1024] overlap size [default=512] pitch threshold (for yin) [default=0.1] silence threshold [default=-70] number of seconds to take back [default=0] temporal smoothing using a median filter of N frames [default=0] maximum pitch values to look for (Hz) [default=20000] minimum pitch values to look for (Hz) [default=20] NOT IMPLEMENTED output notes be quiet Show a summary of options. make lots of noise [default] Plotting options When the Python interface to Gnuplot is installed, the following additional options are available. draw plot of the pitch track draw plot of the ground truth pitch track define horizontal plot size [default=1.] define vertical plot size [default=1.] save plot to output.{ps,eps,png,svg} instead of displaying it BUGS For now the program has only been tested on audio signals sampled at 44.1 kHz.
