How to Convert M4A to WAV on PC with M4A to WAV Converter

"Hello, i have some .m4a music i want to convert to .wav. Is there any free m4a to wav converter that I could use to do the conversion? And is there any degradation in quality with this conversion?"

M4A stands for MPEG 4 Audio, a filename extension used to represent audio files. Music purchased through the iTunes store has been in m4a format since 2007. It is compatible with Apple devices but cannot be used in many former portable devices and cannot be edited in many audio editors like Audacity, Wavosaur, CoolEdit and more. It is also not an ideal format for storing. Converting M4A to WAV could preserve the high quality sound of source M4A audio files and also make the audio files be compatible with more devices.

Actually there are a few good audio converters to convert M4A to WAV files. This post presents to you a few ways to convert M4A to WAV on PC for Windows and Mac.
