Is there a macOS alternative to delaycut or eac3to? I'm looking to edit some audio tracks for movies without reencoding them.

I've searched online, and apparently delaycut and eac3to would be good for what I'm aiming to do (according to an Original Trilogy forum post).  The problem is that that they're both Windows-exclusive applications.  A possible alternative might be Audio Cutter, but some of the reviews on the App Store have me hesitant to pay for it.

Can anyone suggest a macOS application that can do what I want to do?  (I'd prefer something free, but if there's no free option, that's fine.)
If what you are trying to do is extract segments of audio from an audio file and save them to files, then I suggest Audacity.  

It is open sourced, cross platform, and probably can do what you need with ease.
