Most Audition users already know about the Spectral Frequency Display and use it to analyze and repair recordings regularly. But here’s a trick that most people didn’t know about. Did you know that you can record while using the Spectral Display? Dan, one of our QA guys, was the first to point out to me how useful that can be, and since then I’ve talked to a bunch of people about how they this during live recordings to analyze their gear and spot problems in the recording early. In fact, at NAB I spoke to one of our customers who regularly uses two copies of Audition: one on a desktop to do the actual multitrack recording, and another on a laptop monitoring his master mixer output to the house. Not only does he monitor the master out during the show, but beforehand he solos each channel on his board and looks at the output in Spectral Display to see how everything is going to work out.
To do this yourself, just set up a recording as normal in the Edit View by creating a new file and then select View->Spectral Frequency Display to set your display. Next, go to Window->Spectral Controls so you can set your display settings. I like recording in the logarithmic display since it lets me see the low frequencies better. My laptop can handle 2048 bands and still maintain smooth scrolling, but you can select whichever works best on your system.
Then let it roll by hitting the record button. Here you can see what it looks like when I whistle a sweeping tone:
Not exactly Mozart, but it gets the point across.
While you’re recording you can also run your Frequency and Phase Analysis windows for the total data load. You could use the Mastering and Analysis workspace and just change it to the Frequency Display as outlined above.
