I downloaded Wavepad and saved the file in a MP3 format. I want to upload the file to my web site for my customers. What do I need to tell my customers that they need to have installed on their computers in order to listen to my audio? (Do all computers with a sound card have the ability to play a MP3 file?)

I did a recording using Wavepad a few months ago (on another computer). I downloaded wavepad on my computer and edited a few spots. I then clicked on "save file", but I have no success. I even downloaded a mp3 eoncoder--as suggested in some of the other messages. What do I need to do to save my editing. Thanks.
