Audio folks: is there a good/safe way to lossless trim AAC/M4A audio? Is there risk of introducing artifacts using some methods? I have a recording that only exists as a 128kbps M4A file and I’d like to split it into smaller sections.

@misty Fission from Rogue Amoeba is lossless. I don’t edit audio often, but it’s such a perfect tool that I’ve purchased multiple upgrades over the year.
