You can compare decoded raw bitstreams with tools like Audacity but imho it is unnecessary.
Re-encoding with VBR (Variable bitrate) encoding would be the way to go. It will use lower bits when there is less sound information, and will use your maximum provided bitrate when it actually needs it.
Also, I would strongly advise to migrate from mp3 to a better format unless you're hardware locked.
128 kbps opus is said to be transparent (almost indistinguishable from uncompressed form to 99% ears) while 80-96 kbps opus is somewhat equivalent to 320 kbps mp3. And the format is royalty-free with wide support from various OSes.

Never heard of Opus until now. If I can't throw something at a random player and have it "just work", it's not even a contender in my book.
I'm reading that "[...] in many respects Ogg Opus is the successor to Ogg Vorbis". That name, I recognized, and I stopped reading there.
You can have the most awesome format in the world, if the support isn't there, it's a non-starter. Re-encoding is never a good idea, and going down this path to me sounds like having to re-encode in a different format every couple of years for the sake of using the format-du-jour. No thanks.

No, there will not be any such software. In short, your friend cannot return to their original 128k quality files from what they have now.
The process you're referring to is called transcoding. Whenever you transcode across bitrates of a lossy codec, you lose information because the quantitization of the samples is different. So, quality was lost in the 128k -> 320k trancoding. More quality will be lost doing another transcoding from 320k -> 128k.
Maybe your friend is now at a financial point in their life where they can afford to replace the mangled files?

There's "affording" the time, and "affording" the money. Despite the old saying, I hope you're not suggesting both are interchangeable.

Good luck to all there, not just CP members - that's one big explosion.

From the angle shown, it looks like a fire, that set off the explosion. Someone's ammunition dump go up in smoke?
NOT a good day for civilians in Beirut. 
EDIT: according to the Israeli web site www.ynet.co.il (the web site of a major Israeli paper), the small explosions were set off by a fire in a warehouse storing fireworks. The big explosion occurred when the fire reached a warehouse containing a few tons of nitrates. Nitrates, for those who've forgotten their chemistry, are the starting point for chemical fertilizer and also for explosives.

Slight understatement there - the airport (10km / 6 miles from the blast) was damaged ... Latest I've seen is 50 dead, 2750 injured, but they are still looking for the firemen / firewomen who were working on the original blaze. 90% of the wheat for the Lebanese staple flatbread is imported throughn the now destroyed port. And with the recent economic fun-and-games in Lebanon, it's all just going to make a very bad situation much, much worse.

It's worse than that. The big building near the port looks like a grain storage silo. A still picture from another angle shows that the silo was damaged, so even if grain were delivered, they have nowhere to store it!
The two closest ports which have grain-handling facilities are Haifa (in Israel), and Latakia (in Syria). The questions are (a) whether they have the combined additional capacity to handle the grain destined for Lebanon, (b) whether the Lebanese government will accept aid coming via Israel, and (c) whether Hezbollah will interfere with any shipments coming from Israel.

Technically, I think Lebanon is still at war with Israel - I just checked and there has been a cease fire in effect since '07, but there is still border fun-and-games plus Hezbollah working in Lebanon - and as for Syria ... they are still having a civil war, plus what's left of ISIS waiting for an opportunity.
Couldn't have happened in a worse place at a worse time, I guess. What a mess.

Yes, we are technically at war, but Israel has already offered humanitarian assistance including treatment of wounded in Israeli hospitals.
There are logistical and security issues, but I can't imagine the Government refusing to allow the transfer of humanitarian aid to Lebanon via Israeli ports. I expect that many Israelis (myself included) wouldn't stand for it.

I think the biggest risk is not coming from Israeli "normal" people having something against it.

I figured out where the camera was for that shot, right around 3,900 feet away. A wee too close for my taste.
I saw a couple of angles. One from a apartment balcony to the right of this shot, and a bit closer. Another from a boat about a mile, mile and a half, away.
Reminded me of the Texas City Disaster.

The link you provided only supports NVMe M.2 type. It doesn't support the SATA M.2. So if your drive is NVMe then yes, it will work. This is the confusing part of the M.2 type drives.

What do you plan to do with this "clone" of your "main drive"? (A Windows OS probably won't "activate" on a different mother board while the other copy is active).

I am really just planning ahead for eventuality of m.2 wearing out and making sure I can duplicate quickly and get running again.

You are correct went thru those difficulties last year and that is one of the reasons I now run Ubuntu as my main system now. Ubuntu doesn't have that problem.
I can't believe how much I like Linux after using Windows since 3.1 and being a win dev for so long.

And why don't make an Image with AOMEI or Macrium?
If the SSD goes boom, then restoring from the image to a new drive should bring less troubles than cloning an active OS in an extra drive.

Macrium for sure. but you are right. that's a great idea. just make a current image of drive onto an extra SSD then I can restore to any m.2 in the future. great idea! thanks!

When I switched out my .5TB NVMe M.2 for a new 1TB one, I simply used my AOMEI backup boot from a CD. Worked fine.

I was wondering about TotD, so I checked, and found that I missed the fifth anniversary - on 26th Jan 2015 I posted the first of what I figured then was a "one off throwaway": The Lounge[^]
Five and a half years? Good grief ... 
Thank you all for joining in the pun threads that followed - it couldn't have lasted as long without you!
