-MP3 library
------------
-Version 0.2
-
-This decoder is a 'light' version (thrown out all unnecessay parts)
-from the mpg123 package. I made this for a company.
-
-Currently only Layer3 is enabled to save some space. Layer1,2 isn't
-tested at all. The interface will not change significantly.
-A backport to the mpg123 package is planed.
-
-comiled and tested only on Solaris 2.6
-main.c contains a simple demo application for library.
-
-COPYING: you may use this source under GPL terms!
-
-PLEASE NOTE: This software may contain patented alogrithm (at least
- patented in some countries). It may be not allowed to sell/use products
- based on this source code in these countries. Check this out first!
-
-COPYRIGHT of MP3 music:
- Please note, that the duplicating of copyrighted music without explicit
- permission violates the rights of the owner.
-
-SENDING PATCHES:
- Maybe I change the copyright policy (ie some kind of more free BSD licencse).
- Please consider this when sending patches/changes.
- I also want to have the freedom to sell the code to companies that
- can not use the code under GPL. So, if you send me significant patches,
- I need your explicit permission to do this. Of course, there will also
- be the GPLed open source version of the 100% same code.
- For the case you cannot accept this: the code is GPL, it's your freedom
- to distribute your changes again under GPL.
-
-FEEDBACK:
- I'm interessted to here from you, when you use this package as part
- of another project.

-This is a module for asterisk to play mp3 natively.
-They *SHOULD* be already at 8khz and *SHOULD* be mono.
-otherwise they will be consuming CPU alot more than need be.
-
-Convert them to 8k mono like this:
-lame -q -p --mp3input -a --preset 8 in.mp3 8kout.mp3
-
-just run
-# make clean install
-to install
-
-or
-# make clean autoload
