Wav file tagging

[REIKA]

1) MM can read the tag of the wav file written by other applications.
2) Other applications cannot correctly read the tag of the wav file if tag is edited with MM.
3) MM cannot also read the tag of this file when the wav file edited with MM is deleted from the library once, and it registers in the library again.

I examined what had happened with BinaryEditor.
Other applications write tag with Shift_JIS code.
On the other hand, MM seems to be writing tag with UTF8 code.

In the RIFF tag of the wav file, it is sure not to be provided for character-code.
Therefore, it must be usual to use the character-code of the default of the system (As well as ID3V1).
To begin with, it is out of the question that MM cannot read the tag though it was written by MM.

I can't reproduce 3), even though I tried some Japanese characters, they properly remain in WAV tags even after rescan. Can you alway reproduce?

Sorry, 3) occurs not always but sometimes.
I will send you sample files.

[REIKA]

I have not found software that can correctly display the tag written by MM yet.

WMP11 and Winamp5.531 can correctly display the tag written with Shift_JIS code.
On the other hand, the tag written with UTF8 code cannot be correctly displayed on them.
dbPowerMusicConverter reads and writes tag with Shift_JIS code , too.

I do not want to use MM to manage wav files now, because the generality of datas is lost.

This will be configurable in the next release, by specifying

[WAVTagging]
ReadWriteUTF8=0

in MediaMonkey.ini file you will force MM to use plain ASCII (or more exactly the codepage you have in your Windows install for non-Unicode usage).

THX.

So, I will report immediately at BBS in Japan, because this issue had gotten into the news there.

This will be configurable in the next release

Please make compatible mode the default.

If someone interested to Contact the developers of other apps.
Here is how any app can easily determine is Tag in UTF8 or in ASCII:

Example in Cyrillic:
Title=УТФ8 Титле

App fix in Pseudo Code:

Code: Select all

1. get title in Raw Bytes
2. Check result of UTF8->ASCII report
  a. If result > NULL then Title is in UTF8
  b. If result = NULL then Title is in ASCII(RAW ASCII regional settings), Do ASCII->UTF8 Conversion.

This the reason why MediaMonkey reads all the tags correctly (And Why MM can see Japanese ASCII tags even I do not have Japanese Regional settings). This was fixed by MM few years ago when we had problem with German Umulats ("Ü") that can be found in ASCII table.
