Is there an app that will allow me to edit MP3 files Surface with 8.1 RT?

[Windows Central Question]

Trying to find an app that will allow me to edit MP3 files Surface with 8.1 RT

Hi,

I'm running Windows 8.1 RT on a MS Surface... All I need is some simple editing features. In particular, I want to be able to trim audio at the beginning and end of songs to eliminate dead air. After that, I want to be able to save the song. I have M8 (Multimedia 8), and that says it can perform that function, but I can't get it to work...

Any ideas?

Thanks in advance...
