Processing audio in straight perl can be pretty slow; traversing the parse tree takes a good deal of time, to the point that operations like regex matching have their own hand-optimized C engines.
One alternative to generic perl that is great for processing vector data (like audio streams) is the Perl Data Language, or PDL. The vector and matrix operations are implemented in highly optimized C code and are programmed in a Matlab-like dialect that makes it easy to express DSP algorithms.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
