Since gracenote is already used for audio fingerprinting for tagging it would be nice to utilize another one of gracenote’s features.
I think the community would greatly benefit from auto eq.
This is a feature that would need no other interaction from the user other than to enable or disable this option.
At least what I gather from the marketing info on gracenote’s website, it would allow any user to get the best possible sound from any device of their choosing since all of the processing would be done on the server side.
