this is anecdotal; I’ve yet to look into it properly. I just putting it out there.
On a few occasions recently I’ve tagged some otherwise good MP3 files and the resultant tagged file has been corrupted - by which I mean on playback the file has artefacts (pops, etc.). I’ve tested both the original file and the resultant file on multiple players to confirm their quality.
My media is not local to my MacBook, so Picard loads from and saves to AFP shares over WiFi. I’ve only noticed this over WiFi; when LAN connected the files are ok. I’ve not tested SAMBA shares. If I load the original file and save again when LAN connected (WiFi disabled) the artefacts are no longer present.
My WiFi is patchy in certain parts of the house (as exhibited by LONG save times of large files). But Picard doesn’t every complain nor throw an error.
Although I seem to be blaming WiFi I’m not yet sure that’s the problem. I’m wondering if anyone else has experienced issues like this.
