vox -- determine number of simultaneously active pitches in a Humdrum input


vox [inputfile ...] [ > outputfile.vox]


The vox command calculates the number of tones sounding together at successive moments in time. It outputs a single Humdrum spine (**vox#) where successive integers indicate the total number of concurrently sounding pitches for each data record. Multiple-stops are properly supported.

The vox command accepts as input any pitch-encoded Humdrum representations listed below. For descriptions of the various input representations refer to Section 2 (Representation Reference) of this reference manual.

It is recommended that output files produced using the vox command should be given names with the distinguishing `.vox' extension.

**cbrcritical band rate (in equivalent rectangular bandwidths)
**centshundredths of a semitone with respect to middle C=0 (e.g. 1200 equals C5)
**cochocochlear coordinates (in millimeters)
**degkey-related relative scale degree
**degreekey-related absolute scale degree
**freqfundamental frequency (in hertz)
