M4A is a file extension for an audio file encoded with advanced audio coding (AAC) which is a lossy compression. Most M4A files of
iTunes are DRM protected, and you can’t play them freely as you like.
WAV is a Microsoft/IBM audio file container format. It is the main format used on Windows systems for storing uncompressed, lossless
audio. And the most common WAV audio format is uncompressed audio in the linear pulse code modulation (LPCM) format.
Though a WAV file will be significantly larger than a MP3 file, the old-version WAV has only one audio channel and WAV files are limited in size to 4
Gigabytes, WAV files are “lossless” files which means that the WAV file doesn’t lose any of its quality when it is stored, whereas MP3 files are “lossy”
files, has higher audio fidelity than MP3 files, and WAV files can be edited or they can be manipulated relatively easily. So converting to WAV
