Looking for a good tool/application to split single music file into many

[Sprhmn Unknwn]

Hello!

So I have two different .m4a files from two different concerts, that I want to split into multiple tracks (obviously different lengths that I'd need to change based on the song) with seamless transition.

What's a wonderful tool and technique(s) to pull this off?

Thank you.

Use Apple's Garage Band. You likely already have it on your Mac.

Knowing absolutely nothing about Garage Band, how would I go about pulling off what I want to do?
