Usage: ./acr_extr [options] [-i infile]

!NOTE
The default parameters of this tool are for generating database fingerprints（used to upload to the bucket), not identification fingerprints.  
If you want to use the fingerprint for identification, please add the -cli parameter.

For Example:
    # ./acr_extr -i inputfile
    # ./acr_extr -i inputfile -o outputfile

Getting help:
   -h      -- print basic options
   -v      -- print vertion

Options:
   -i           input file
   -s           Start time of input file, default is 0 

                 example: ./acrcloud_extr -s 30 -i inputfile   (It will skip 30 seconds from the beginning.)

   -l           Length of audio data you need. if you create recogize frigerprint, default is 12 seconds, if you create db frigerprint, it is not useful. 

                 example: ./acr_extr -l 12 -i inputfile   (It will decode 12 seconds audio data from the beginning of input file.)

   -o           Output file. If do not have this option, dir of output file is the same with input file.

   -cli         If you add this option, it will create recognition frigerprint. 

                 example: ./acrcloud_extr -cli -i inputfile

   -au          If you add this option, it will save the audio data is decoded from input file(formatter: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 8000 Hz). 

                 example: ./acr_extr -au -i inputfile

   -t           the duration of one block, default is 10 minutes.
   --debug      If you add this option, it will print all infomation.
