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)
