For performing I use MP3@320kbps. After all I play to folk that are eating, chatting, elderly and or hard of hearing in some other way. I play the music through a PA in buildings that have air conditioners blowing away, or a bit of 50 cycle hum and/or many other extraneous noises. I don’t think anybody even if they were listening closely could pick the difference between the MP3 or a .wav in that environment.

It is possible to find the losses and have a listen to them. In a nutshell you could pull both the .wav and 320 kbps MP3 into something like Audacity. Set (normalise) them to exactly the same level, ensure both are set exactly at the same time, invert one of them then play the song. The tracks will pretty much cancel out. The sound you are left with is the losses. @320kbps the result is not that much, usually high end sound most people struggle to hear.

@128kbps you will hear more losses.

That was my experience.
