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.
