I downloaded a "Linux ISO" which came as a series of *.opus files. My iPhone doesn't recognize them, so I was wondering if you guys might recommend a program to convert them to *.mp3 files.

Ideally a mac or linux based program with a gui. Any suggestions?

If you really need to convert the files to something like AAC for native iPhone playback, I would suggest either fre:ac (audio only) or MKVToolnix (video and audio).

FYI MKVtoolNix doesn't do transcoding, it simply allows you inspect/modify metadata and demux/remux data streams into an MKV container.it's indeed useful and I use it often, but it wouldn't be for OP's use-case.

Oh dang, you’re right. I used to use StaxRip back when I was doing more encoding and then finish with MKVToolNix, but I think the gui is Windows only.

Probably should have recommended Handbrake.

I'll look at both of those suggestions but mp3 should be sufficient, no?

AAC is higher quality for the same compression level and generally preferred by Apple. MP3 should be fine too though.

EDIT: To be clear though, the programs I listed can handle all kinds of codecs including AAC and MP3. fre:ac is also good for ripping CDs if you’re into that sort of thing.
