augment

augment

Change 1 or more wave files using 1 or more of the available augmentations.
Augmentations are done independently and are not chained in sequence.
Augmented wav files are renamed to include a transform indicator. Ann index
is included in the file name if the augmentation produced more than a single
result.
Usage : ... [-o dir ] [-f list ] [-log r] [-m file ] wav files 
Options:
  -m file : sets the location of a metadata file defining labels. Causes
              a new metadata.csv file to be created in the output directory.
  -o dir  : sets the directory to store wav files.
              Required when metadata.csv is present in the source directory.
              If not specified, then the source directory is used.
  -f list : specifies a list of 1 or more frequencies by which to shift 
              the sounds
  -log r  : take the log of the signal values for which the absolute value
              is greater or equal to r.  Smaller values of r accentuate the
              fainter sounds relative to the louder ones.  All signal values
              are in the range [-1,1].
Examples: 
   ... -log .01 one.wav two.wav 
   ... -m metadata.csv -log 0.001 one.wav two.wav 
   ... -o mydir -m metadata.csv -f -10,0,10 one.wav 

partition

Partition a set of sounds defined in a metadata file into 2 or more partitions.
For each label value of the specified label, partitions are balanced on the 
number of sound files for each label value.
Usage: ... -label name -dest-dir dir [-partitions n] [-seed n] `dir or metadata file`
Required options:
  -label name : label on sounds used to attempt a balanced partitioning.
  -dest-dir directory : directory into which to place partition sub-directories
     containing the metdata file and optionally the sounds in the partition.
Optional options:
  -partitions n : sets the number of partitions to n. Default is 2.
  -seed n : use another random seed to change randomization.
  -copy  : copy the sound files to the partition directories.
     Default is to reference the original files in the metadata.csv files
     written to the partition directories.
Examples: 
  ... -label status -dest-dir mydir mysoundsdir 
  ... -label status -dest-dir mydir -copy mysoundsdir 
  ... -label status -dest-dir mydir -partitions 4 mysoundsdir
