It's not really about the sound editor .... I used the sound editor MagixMusicMaker just to check out the sound content in the file after I've heard the artifacts in the media player "MediaMonkey" and in several games .
This artifact at the beginning of each file can be listened by a media player . If you want i can upload for you several files , In all you will find the artifact by using a visualisation of the content in your sound editor , And I just found one file that the corruption was so big that it made it possible even to hear the artifact as a scratch noise at the beginning . In some certain video game i tagged it's music then I could hear the artifacts at the beginning of each track while playing , So it's surly not the sound editor .
You may take one of your music files (that was tagged with the latest 2.55a version and tagged anything possible+art+comment and maybe you will see in your sound editor the artifact . When the tagging contains bigger content the artifact should become larger . And only then you can hear it .
BTW here is some basic info :
Windows 8 64 bit
Mp3tag v2.55a
MediaMonkey v4.0.7.1511
mp3test - the latest one
Magix Music Maker v15
Helium Audio Converter 1.8.0 build 365
Format Factory - The latest one ..
My working environment ? Hmm , I am not a soundman or sound-editor anyway, I am a software developer (.NET C#) . I use music(and soundtrack editing) for common media and entertainment purpose . My most used sound-related software is mp3tag to edited tags and organise the files . lol
BTW 2:
I think this reported bug is actually referring to the same issue . Isn't it ?
Edit :
I am downloading now Nero Wave Edior to check out the file ... it's just obvious that all my mp3 files contains artifacts MMM and MM won't display and play data that doesn't exists in the files ..
