AAC, Mp4 And M4a File Properties

Hello All:

Do any of you know any app that can read AAC, Mp4 and M4a file properties accurately?

WXP can't, and neither can EncSpot Pro, dBpowerAMP, Media Info, Mr. Questionman, Audio Identifier, and anything else I have tried.

I want to get the bit rate, sample size, sample rate, encoder settings, etc.

I am using both Nero 9 and EAC with NeroAacenc.exe to rip files, and I can't get any readings from the ripped files with either the .aac, .mp4 or .m4a extensions.

Any advice or URLs you could provide would be greatly appreciated.

Thanks in advance for your consideration.

Marc

MediaInfo doesnt?
The text or tree view both give out a lot of info:
