Convert WAV files to FLAC

The easiest way that I've found to convert your WAV audio files to FLAC format so they're compressed without losing any audio quality is to do the following:

1. Make sure you have Chocolatey installed (which should be on every machine already.  :-) ).
2. Open an elevated PowerShell prompt and run the following command:

   1.  choco install -y flac
      

3. Now change to the directory containing your WAV files and run the following command:

   1.  flac --best *.wav
      

I found this solution here.
