How to determine audio file format for importing to Audacity or Cool Edit.

I have an audio file in .wma format from a recording of a meeting that was made on a laptop.  I don't know anything about the recording system.

I can open the file using Nero Show Time and hear the audio, change the speed, move forward and back, etc. etc.
I wonder how Nero Show Time knows how to play it?

I want to filter and equalize the file and intend to use Audacity or Cool Edit.  But, I can't find the format to choose for opening or importing the file.  All I get is noise for every set of conditions I've chosen.  

How might I get this file opened so that I can work on it?

You have to convert any compressed file to a wav file to edit it. Cool edit will import mp3s, as will Audacity -- but might not want to deal with WMAs.
So, simply convert the file in either iTunes or Super to a 44.1khz stereo wave file.

Here is an open source program that displays all relevant information about audio/video files:

However in your case I don't think Audacity or Cool Edit support the audio codec used in the recording. So you have to convert it to a supported format. Easiest is to convert to.wav but file size will be big but this isn't probably important. Many programs can convert to .wav such as VLC, winamp and graphedit.

I ended up using dbPoweramp music converter. iTunes wouldn't do it.

If you need to do it in iTunes you have to change the import preference to wav format and it will convert any file to a wav file.
