What is an mp3 and will it play in my car or home stereo?
An mp3 is a type of audio file that has become popular for its size and versatility. The benefit to mp3s is that they are small in size so they can be downloaded and transferred fast. If you create what’s known as an mp3 CD from your audiobook download, you won’t need as many blank CDs (in most cases, one disc is enough for an entire audiobook).
