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:
- Make sure you have Chocolatey installed (which should be on every machine already. 🙂 ).
- Open an elevated PowerShell prompt and run the following command:
choco install -y flac
- Now change to the directory containing your WAV files and run the following command:
flac --best *.wav
