I am trying to convert 5 mp3's in to 1 .wav track. Where is the plug-in

The diskwriter plugin will convert mp3 files to wave. The FAQ is here -

This will give you 5 wave files though. You can either use a sound editor to join them together or try the SQRsoft diskwriter plugin which converts files to wave and joins them. (Supposed to, doesn't seem to work for some people. Try it anyway)

It's here - http://sqrsoft.audiogalaxy.com/files/out_mix2dsk.zip
