Hi,
WAV tagging in foobar2000 (1.2.6) creates a second "id3" chunk.
Wavelab 8, after loading the .wav file without any tags, and added the value "ABB" to TPE1:
00000000h: 52 49 46 46 AA F0 21 02 57 41 56 45 4A 55 4E 4B; RIFFªð!.WAVEJUNK

Wavelab8 stores the ID3 chunk at the beginning, not at the end of the file.

Then I loaded the track into foobar2000 (1.2.6) and updated TPE1 with "ABBA":
00000000h: 52 49 46 46 D4 F0 21 02 57 41 56 45 4C 49 53 54; RIFFÔð!.WAVELIST

The "id3" chunk TPE1 is unchanged, but foobar2000 has created a 2nd "id3" chunk at the end of the file:
0221f0b0h: FF FF 69 64 33 20 22 00 00 00 49 44 33 03 00 00; ÿÿid3 "...ID3...

0221f0d0h: FE 41 00 42 00 42 00 41 00 00 00 00 ; þA.B.B.A....
which is a bug.

After that I re-opened the track in Wavelab 8 and updated TPE1 with "AB" (btw. the old value shown was "ABBA" - maybe overwritten during the loading from the second "id3" chunk).

Wavelab 8 has removed the second "id3" chunk (correctly).
Please fix it for 1.2.7 - THANKS.
