Hi. My OS is Windows 7 Pro_64 bit
I’ve 10.000 mp3 files created in the last five years:
. tagged with mp3Tag v.2.53 (Mpeg options: READ ID3v1 and ID3v2 checked; WRITE ID3v1, ID3v2, ID3v2.3 UTF-16 checked);
. analyzed with mp3Gain (only analyzed, NOT Normalized);
. imported in iTunes (either iTunes 8 or iTunes 10) with Sound Check option turned on.
The Volume adjustment has been always calculated by iTunes (Sound check on) and is satisfying for me.
The mp3Gain APE information has been already read and extracted in an Excel file, using mp3Tag: everything is OK.
Now, using mp3Tag, I exported also “iTunNorm” field and all the generic “Comment” fields in order to interpret the Check Sound info written by iTunes; and I realized that I’m three different situations:
- Many files have the Check Sound info written in a generic “Comment” field;
- Many other files have the Check Sound info written in a specific “iTunNorm comment” field;
- About 1000 files don’t have the Check Sound info written anywhere (neither in a generic Comment field, nor in the iTunNorm field).
In this third situation, the Volume Adjustment is well calculated by iTunes but, using mp3Tag, I can’t see any meta-tag info concerning Check Sound.
Moreover: if I add a new mp3 file in iTunes (10) library, the Sound Check is well calculated (there is a coherent Volume Adjustment in iTunes Get-info), but, using mp3Tag, I can’t see any Check Sound info neither in a generic comment field, nor in the specific iTunNorm field.
. any idea about why I can’t see the Check Sound info using mp3Tag in (1.000) of my (10.000) mp3 files?
. how can I found Check Sound info in these 1.000 files ? (it must be somewhere because iTunes Volume Adj has been well calculated)
. did iTunes 10 stop to use iTunNorm field to write Check Sound info in mp3 files?
. if “yes” where iTunes writes Check Sound info and how can I read and exported Check Sound info using mp3Tag (preferred) or any other software?
Thanks in advance for your replies
