NAME

       ecalength - prints audio file length and other information

SYNOPSIS

       ecalength [-ahtsfmbcr] FILE1 [FILE2] [FILEn]

DESCRIPTION

       This  is  ecalength,  a few lines of code pompously named so because they let one retrieve
       the length of an audio file from the command line using ecasound’s engine.

       Limitations:

              - With files without header information  (raw  files),  ecalength  will  only  work
              correctly if the audio file is at a sampling rate of 44100 hz.  (Addressed with the
              -a switch.)

              - It is not foolproof, feeding it with something other  than  an  audio  file  WILL
              result in ugly things being spewed back.  (A bit better)

              - A thousand more that I haven’t thought of.

OPTIONS

       -h     Prints this usage message.  (help)

       -a[:]bits,channels,rate
              Changes the format assumed by default for headerless data. (adjust)

       -t     Prints the summed length of all the files processed.  (total) (Ignored if with -s)

       -s     Enables  script  mode:  One  info  type  per file per line.   (script) (Defaults to
              length in secs.)

       -f     With -s will return the format string as info, alone it will add  it  to  the  main
              display.  (format)

       -b     If  -s and -f are enabled with this the info printed will be the sample’s bitwidth.
              (bits)

       -c     If -s and -f are enabled with this the info printed  will  be  the  channel  count.
              (channel count)

       -r     If  -s  and  -f  are  enabled with this the info printed will be the sampling rate.
              (rate)

       -m     Will print human computable time as in main display but in batch fashion. (minutes)
              (Only with -s)
