A nice side benefit of the Media Foundation engine in X3D, is that it adds enhanced audio import capabilities. In addition to previously supported audio formats, X3D can now import:
- MPEG4 audio (.M4A)
- Better MP3 import compatibility (SONAR previously couldn't import MP3's authored from several sources like Apple devices, Amazon, etc with album art and certain ID3 info, due to limitations in DirectShow)
- Audio streams from all supported video formats 
 

Awesome! I've had the dreaded problem in the past, when importing mp3's, Sonar would give me the "out of memory" message. So that's fixed?

so...would I need to uncheck the 64 bit double precision engine if I import a 128kbps MP3 file?  ;-D~

Yes, the out of memory error was a symptom of that failure.

Very cool! Thanks Noel!

Just make sure you turn it back on before exporting back to 128kb/s.
