Cleaning up Audio Recording

Dear All,

I made a short recording at a concert I attended recently - while the vocals and instruments are distinguishable, I’d like to see if there is anything at all possible to clean up the audio quality as much as possible.
I have attached a sample for your expert ears - any ideas what I can do?

The original recording was made in AMR format, but when making this snippet, it exported to mp3 format.

Regards,

There’s not much you can do as the recording is fairly low quality and you can’t put back what is missing.
You can make the sound a little less “muddy” with the Equalization effect. http://manual.audacityteam.org/man/Equalization
