So basically I want to split a bunch of .mp3 files that Ive recorded with a scrreeen recorder app uinto their left and right channels and then make both channels of the song either both left or both right. But I dont currently have any way to downlowad Audacity or use the audiolab app on my android phone.

Or can I actually download Audacity onto an android phone but I just havent loooked enough into how to do that yet?

So what other options do I have that I havent consodered?

Thabnks to anyone that helps.
