Metadata (TAG) written into the audio file (mp3) destroying sound.

You might have missed to read the full post of ‘Fred48fm’.
His final answer was:
“... Hi,
Problem solved...!
I'm deeply sorry for the time you spend on this.
The problem seems to be ... a faulty SATA cable...”

I am also really sorry, that you seems to be very frustrated.
But wouldn’t know what to do more. I can not reproduce your case.
I will send you an MP3 with various TAG writes and ACPD to it

Here comes a test .mp3 file.
Before the upload i just added various meta data incl. ACPD plus some manual additions.
It does not contain any glitches...

As suggested, it would be better, if you send me one of your files to test with, if it file specific?!

Attached also the marked settings you have been asking for beforehand.
Please click on the '?' to get detailed information on each.

If you disable the 'Auto Save...' options (as they are by default) NO meta data is automatically written.

Finally 'kzlosnic' has send me his original file!

What I did:
a) I renamed the original file to …- ORIGINAL.mp3
b) I copied that to …- MODIFIED.mp3
c) I wrote some TAGs to the MODIFIED.mp3 file incl. ACPD
d) I used MP3-CHECKER to verify both files before and after and made a screenshot

BOTH files have been fully okay!
ORIGINAL and MODIFIED both sounded exactly the same, the MP3 data chunks are unmodified and uncorrupted!
Only the ID3v2 chunk has been modified.
Did the same on 3 different PCs - all the same result.

Please find attached all files for your reference and prove:

I don't believe with UFO. Something has destroyed my audio files. I got full report from my employed IT guy. He said "nothing is wrong with NTFS file system. The Hardware RAID5 100% Health".
Question:
1. What release of windows did you test with?
I have Windows 10 Pro compilation 20H2 with .NET Framework 4.8



I have RAID 5 system based on FUJITSU PRAID CP400i - 8 port 12Gb/s SAS, 6Gb/s SATA
I have 4 HDD WD60EFAX (6TB) disks.

Something is wrong but we both don't know what is happening and that is very scary.

[radio42]

That is fully true. I used one older Win10 and two new ones.
The other user had a hardware defect, that’s why I didn’t consider it.
Maybe you have a 2nd PC just to make another independent test yourself.

I had (so it looks to me) a similar problem, ALMOST! PF could be playing for some time, all audio sounds fine, until at some point all audio sounds distorted. The problem was the soundcard. (USB-console with built-in soundcards)
Kzlosnik try this: When this happens try to load the same file with "Windows Media Player" is the audio still "distorted"? Maybe even restart the PC and see if the problem persist.

I agree with Bernd: Metatag-saving does NOTHING to the audio, the tags are saved in a portion of the file that is not read by any software as "audio-bits" but in a block that can only contain tag-information. I've had about 8000 files from another system with som proprietary data written in a special block, PF did not read any of that data and no audio were distorted from that data.

Many thanks ’Inzane8305’:

When a build in USB soundcard after some time gots distorted, this is typically and issue for the support of that manufacturers.
I once had a case where using ASIO4ALL helped to overcome those driver issues. This changes the driver model from WDM/WASAPI to ASIO and in that case ASIO4ALL was much more stable.

But I am afraid this is indeed a different case.
