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.
