Quote: When I import an MP3 file into the Wave Editor and subsequently save it, all of the metadata, e.g. Track number, title, artist, are blank.

I am using PD 10 and whatever wave editor came with it. Does the latest-and-greatest- version (the free download on the Cyberlink main web site) do the same or will it retain this information?

Why are you importing it into Wave Editor? Are you making changes? If so, that is a different piece of music and the original etadata no longer holds. Where are you importing it from? .

I am using Wave Editor to, well, edit the file: trim dead space at the beginning and end, add effects, etc.. The original attributes: Title, Artist, Album, Genre and so forth, do still hold as it is the same piece. Custom computer: 8 processors, 16G Ram, ,C: drive 250G solid state.

The original artist would argue that it is NOT the same piece if you trim it and add effects. The program agrees with that.

Actually the information is still there as a music tag but it needs to be re-identified. I opened Wave Editor and cut out part of the audio and saved it as a new file. When I looked at the audio tag (with another program), all I got was the name if the edited file. I used that program to go out to the web to identify it. It identified it properly.

How are you looking at the audio tag? .
