sphinx_pitch - Extract pitch from audio files
sphinx_pitch [ options ]...
This program reads audio files and analyzes them for pitch and voicing. -c file for batch processing -di directory, input file names are relative to this, if defined -do directory, output files are relative to this -ei extension to be applied to all input files -eo extension to be applied to all output files -flen Number of seconds in each analysis frame (needs to be greater than twice the longest period you wish to detect - to detect down to 80Hz you need a frame length of 2.0/80 = 0.025). -fshift Frame shift: number of seconds between each analysis frame. -i audio input file -input_endian of audio data (will be determined automatically if not given) -mswav Defines input format as Microsoft Wav (RIFF) -nist Defines input format as NIST sphere -nskip If a control file was specified, the number of utterances to skip at the head of the file -o text output file (standard output will be used if not given) -raw Defines input format as raw binary data -runlen If a control file was specified, the number of utterances to process (see -nskip too) -samprate Sampling rate of audio data (will be determined automatically if 0) -search_range Fraction of the best local estimate to use as a search range for smoothing. -smooth_window Number of frames on either side of the current frame to use for smoothing. -voice_thresh Threshold of normalized difference under which to search for the fundamental period.
