Wischlist:

It would be usefull to have a sound quality column in the mixxx library.
Especially for external track sources like USB sticks from the party host.

This should be take the signal noise distance and the frequencies into account.
Maybe we can add a vamp plugin for it.

The complexity of an implementation may vary from a simple cut-off frequency analysis to sophisticated frequency spectrum pattern recognition.
