<p>
<h2>NAME</h2>ecalength - prints audio file length and other information
<p>
<h2>SYNOPSIS</h2>
    <strong>ecalength</strong> [-ahtsfmbcr] FILE1 [FILE2] [FILEn]
<p>
<h2>DESCRIPTION</h2>
<p>
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.  
<p>
Limitations:  
<dl>
<p><dt><strong></strong><dd>- 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.)
<p><dt><strong></strong><dd> - It is not foolproof, feeding it with something other than an audio  
        file WILL result in ugly things being spewed back.  
        (A bit better)
<p><dt><strong></strong><dd> - A thousand more that I haven't thought of.
</dl>
<p>
<h2>OPTIONS</h2>
