No doubt it's possible to corrupt an MP3 file if an MP3 tag editor is somehow buggy. That's why I tend to take the time to listen to MP3s after I rip a CD and then tag the files (or take an existing MP3 and just re-tag it...I'm paranoid in that way).
But what about files that have simply been left sitting on disk for months or even years?
I have MP3s that seem to have developed audible clicks and ticks and simply garbled sound without me having changed them in any way, shape or form (as far as I can tell). If an MP3 player offers to "automatically update tags with information downloaded from the internet", I disable that.
I realize bit rot is a thing, but if I'm otherwise not noticing any sort of data corruption with any other type of file...why would this only happen with MP3 files? Digital files are just that, 0s and 1s, and I see no reason for them to change on their own over time (that should simply not ever happen)...yet I'm hearing evidence some of my MP3s are not what they used to be...
Thoughts? Speculation...?

v1 Tags are appended to the end of the file, while v2 tags are prepended, if I remember properly. There is no reason for a tagging software to modify anything inside the audio stream.
I digitalized all my cd's to mp3 years ago, and I still listen to them, having transfered them numerous times between my computers/phones/NAS; I never noticed any degradation of the audio signal.
Did you test offending files on several equipments, to be sure the file is the culprit?

your machine doesn't like your taste of music.
but serially have you tried playing it with another app, or perhaps another machine? maybe the original encoding app "relied on some feature" which player updates have since "fixed"?

Better or worse error correction in the mp3 codec ?
I'd rather be phishing!

It's almost certainly NOT the MP3 itself. I would suspect the player. Try another one.

See my other responses. I've tried multiple players, and - in some cases, if I have an older backup that plays fine - a binary comparison will show the files are different...
|

As others have said, I would suspect the player not the files. The only 'scratches' I hear from my library are those tracks that were ripped from CDs.
BTW, long ago I started a personal project to catalog my music library by using the ID3 tags. I found out quick that they are totally unreliable and have major shortcomings that made them unsuitable for that purpose. (truncated names either at 30 or 60 chars depending on version)

Those are ID3v1 tags. ID3v2.4, which has been the dominant specification for almost 15 years, is a lot more flexible. I use a program called MP3tag[^] and have found it to work well.

That's the one I use.
I find it doubtful it's the player, as I've tried WMP, VLC (my player of choice) and foobar2000.
Also--and more importantly--every once in a while I come across one of those files, then look it up in my most recent backup set. If I'm lucky, I didn't yet overwrite the "good" backup of the MP3 with the version on my NAS (now with the audible clicks). And if I do a file compare, the files are different. I think that, by itself, rules out any sort of playback mechanism subtleties between different players.

And now over to the next step: corrupting MP4's 
|
|
|
|

This sort of thing is part of the reason I don't convert my DVD rips (AUDIO_TS/VIDEO_TS, VOBs and all) into single-file formats...

Wise, very wise
TS stands for Transport Stream btw. a format that I don't encounter very often in my line of work.
I once had to analyze a TS, it was hard to find any information about that !
|
|
|
|
|
I've come across .TS files before, and I believe they tend to originate from Tivo and live stream type of boxes that receive streaming data you're not "supposed" to get to. And it's hardly compressed (to the point of being total overkill - as in, gigabytes for just a few minutes worth of video).
|
|
|
|
|
My first encounter with .TS was with an early version of a Chinese Digital Video Recorder.
They tried to sell it as "able to deliver H264 streams", but the streams were not in standard H264 format at all, instead it produced .TS
They cleaned up their act btw (but you never know what tricks they are up to next of course)

As I've been made to understand, don't confuse codec with container.
I'm just glad I don't write software that tries to do anything with video files.

.TS transport stream video is the format used by my digital TV in the UK when it records DVB programmes in SD to USB thumb drive in real time, I also have a Grundig box that does the same thing.
I am guessing that this is the video format inside the DVB digital video broadcast signal.
No problem playing this back on TV,Mac or PC using VLC. Sometimes have to rename as .MPG to play.
Single container files approx 2Gb per hour = 25kbps audio and 15Mbps video at 25fps in SD format.

That sounds a lot more reasonable than those I've come across. I mean, I have standard 3-4 minute music videos (that only last as long as a song) roughly 1.2GB.
