MP3 files are great because they are small in file size and almost everything that plays sound will play MP3s. I used iTunes to transform Karen's aiff file to MP3. Perhaps you could use use your music playing software to save as MP3? I am sorry I do not know which Windows software is easiest to use.

   If anyone wishes you may email me (paul at petoftheday) your sound file of any size and I will convert it to MP3.

(I know Windows users can download the iTunes software for free from Apple but there is probably an easier way.)
