both WAV and AIFF have similar limitations for storing metadata.
FLAC is the best choice as previously stated; ALAC also can handle almost as much. My son does this because he uses Applelossless for his ipad.
Now as for your question for the image files ... if you already have images in the album folder (like folder.jpg or cover.jpg), this is an easy fix. Test by selecting the tracks off a wav album => right click => Cover Art => Quick find in file. If you have configured the audio options of MC to look at the album folder for the cover art, this will associate (embed if possible) the art. If this works you can select all your tracks and do this with one action. This also can work in the opposite direction if you have embedded art but no folder.jpg in the file (save cover art to external location ....)
Concerning the tag data that WMC player gets, that JR does not ... I can't see why JRiver would not get everything that Windows Media could get. Maybe you can indicate the precise tag name that is not being imported?
Hope this helps
there is an audible difference between listening to the cd and listening to the FLAC version. both AIFF and WAVe sound better.
sorry to duplicate what 62333638 but let's not go there on this forum, please
Have someone help you, and do an ABX test. Make sure that the samples are short and are exaclty the same volume (gain) Comparing a CD to anything is tough unless you can insure that the outputs are exactly the same, especially regarding volume, and the same DAC is being used etc. read this please and pass it on to anyone who might share his point of view.
