[uug] grep, sed, or awk?

[AJ ONeal]

Is it possible to use grep to print out groupings rather than the text I'm
getting?
If not, I'm supposing that sed or awk is the right tool for the job?

AtomicParsley 02\ Promise.m4a -T | grep 'Atom mdat @\(.*\)of size: \(.*\),
ends @ \(.*\)'
Atom mdat @ 589869 of size: 5716586, ends @ 6306455

I'm using this info to create data-only (no tag / metadata) checksums of m4a
and other mp4 files.
