If you want to play audio files in your posts, then this plugin will be handy. 
Once installed, this plugin allows you to insert mp3 audio files into your posts and pages. This is how you insert the flash player in your posts:
[audio:podcast.mp3]
In this example, the flash player will load the file name called “podcast.mp3″. Additionally, you can load mp3 files from other sites (if you know the source path) as well.
You can also play multiple files at once like this, just separate them by comma:
[audio:file1.mp3,file2.mp3,file3.mp3]
If you are podcasting, plugin has additional options that you can use.

I actually wondered what some of the bloggers used to play various broadcasts. I think it was a very similar plugin. This one looks like it does the job as well. Good stuff!
Thanks for the tip. Will check it out.
Actually, this is a great tip. I am just setting up a new blog and this advise has come in very handy. Thanks.
Great tip, thanks…
Thanks for the tip – I’ve always been doing it the manual way by setting up a custom flash player.
The problem with that was that you had to create a new one for each mp3 created. After a while it got confusing!
