NAME
sphinx_pitch - Extract pitch from audio files
SYNOPSIS
sphinx_pitch [ options ]...
DESCRIPTION
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.
