Some dude - 2017-10-29

Hello, dumb newbie question:

I have a large collection of CDs ripped to my PC (and in turn copied to my phone). Meaning of course multiple mp3's (tracks) in any given folder (album), and multiple albums. Hundreds of albums, thousands of tracks. If it matters, they were all ripped at 128kbps, an acceptable bitrate for my needs.

Is it possible to apply one batch volume normaliztion command to every mp3 child file in parent c:{my music collection}? It is time prohibitive to normalize one album at a time, let alone one track at a time.

Thanks for any and all help!
