THE AUDIO FILES ARE FROM THE CSGO VERSION: 1.35.6.8
You need to convert the audio files to mp3 yourself
Either download/install "Format Factory" OR use this online tool
Okay I just tested with FormatFactory it work for 1000 files : http://www.pcfreetime.com/formatfactory/index.php
WARNING DURING INSTALLATION - This is a old soft and it's a bundleware so it proposes to install avast or some useless things like this, just decline
or just download format factory (the most convenient tool i've ever used EVER) just create a shortcut on the desktop and then drag and drop your video on the shortcut icon on your desktop and it will prompt you with a window where you can change it to any video (or audio) format you like, i don't know why it's not known its a very powerful piece of software that everyone should have
If you want an alternative, you can also use AutoGK and MediaCoder or even FormatFactory
If you have access to a windows PC, may I suggest trying Format Factory? I use it to convert videos for all kinds of reasons, including making a 240p video collection for my romsets. It's very powerful yet easy for a novice to figure out. Check it out here: http://www.pcfreetime.com/formatfactory/index.php?language=en
