Part 1. AU vs. WAV: Why Need Converting AU to WAV

AU is not a commonly used format and does not play with the majority of the players and the devices. Developed by Sun Microsystems, AU is mainly used by the Sun and other Unix based machines. These files are smaller in size and have poor audio quality. 

WAV on the other hand is a widely used Waveform audio file format, developed by Microsoft and IBM, this is a container format that is capable of storing the data of the file like the tracking number, bit rate, sample rate, and more. Being uncompressed and lossless, WAV files are larger in size and offer high-quality audio.
