<h1>ecalength</h1>
<h2>18.04.2004</h2>
<p><h2>NAME</h2>
ecalength - prints audio file lenght 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></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></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></p><dt><strong></strong><dd> - A thousand more that I haven't thought of.
</dl>
<p><h2>OPTIONS</h2>
<p><dl>
<p></p><dt><strong>-h</strong><dd>
Prints this usage message. (help)
<p><p></p><dt><strong>-a[:]bits,channels,rate</strong><dd>

<p><p></p><dt><strong>-t</strong><dd>
Prints the summed length of all the files processed. (total)
(Ignored if with -s)

(Defaults to length in secs.)
<p><p></p><dt><strong>-f</strong><dd>
With -s will return the format string as info, alone it will
add it to the main display. (format)
<p><p></p><dt><strong>-b</strong><dd>
If -s and -f are enabled with this the info printed will be
the sample's bitwidth. (bits)
<p><p></p><dt><strong>-c</strong><dd>
If -s and -f are enabled with this the info printed will be
the channel count. (channel count)
<p><p></p><dt><strong>-r</strong><dd>
