Add a scan frequeny function to the spectrum analyser
The idea here would be to highlight a wave and scan its frequency response from start to finish over time. The results would show frequency anomalies specific to that entire wave. If you could add a graphic readout with DB on the side and frequency on the bottom that would be helpful in identifying what specific frequencies are problematic and also show how many dbs to add or subtract from the noted frequency. If you could overlay that graphic readout with the sonar EQ, it would be helpful in determining the Q for those frequencies that you want to manipulate. This feature is part of Adobe Audition and it takes the need for critical hearing out of the process of equalizing tracks. It also shows where you have frequencies that are absent in your masters. I have found this very useful in identifying problems in my mixes.
