What is an audio converter? 
An audio file converter is used to convert one type of audio like an MP3, WAV, WMA into another type of audio file.
If you have run into issues playing audio, you are not alone. Depending on what software you are using to play the audio, a certain file type may not be supported. The reason this happens is because because not every audio file is created equal. Different audio file formats store data in different ways, and those differences can produce different behaviors and problems. If that’s the case, you’ll need to convert your file to a type that is supported.
Audio converters can convert you files into types that your software supports. Here are list of the top 7 free audio converters.
