Sometimes, it is desirable to view the average spectral content of an entire wavefile. There are several ways to do this.
1. Highlight the entire file. Open up the CNF (Continuous Noise Filter) and click the "Sample Noise" button. The display will show the average frequency response of the file. If you want to save this graph, you can save it as a preset. This method is the fastest approach.
2. Bring up the Spectrum Analyzer, and play the entire file into the system using Averaging Mode. The only reason that you may want to do it this way is if you want higher frequency resolution compared to the CNF method, since you will need to wait for a few minutes for the system to integrate up. The spectrum analyzer has the capability of creating up to 65,536 fft's whereas the CNF is limited to 16,384.
3. Bring up the Spectrum Analyzer, and put it in "Slow" mode. This will give you more of a moving real time view of what is happening within the sound spectrum as the file plays. You can Preview the file via an EQ while this is occuring to see what effects that you are having on the file.
I have heard it said that one should strive to flatten out this spectral display with an EQ. Most often, this approach will not produce a very pleasing result. The reason is that music generally does not contain equal energy at all frequencies (that would befit the definition of noise more than music). However, when transferring olde acoustically recorded 78's, Cylinders or Diamond Discs, sometimes you can correct obvious recording system resonances (and/or anti resonances). These resonances were produced by the recording horn and the cutter diaphram when they were mastered. You can use the 20 or 30 band graphic EQ's or the Paragraphic EQ to do this. You can view the before and after results using the frequency spectrum display techniques that I just described.
Note: Only the Forensics version has the capability to completely compensate for each measured frequency bin created when the spectrum analyzer is used at its extreme settings in resolution, since it is the only version that offers a 32,000 band graphic Equalizer (called the Spectral Filter).
