Selecting "Sequence Information" from the Sequencer's Sequence menu opens a dialog that displays key information about the sequence, allowing you to change some of it:
The Sequence Information dialog
Audio Information
If your license level is below Pro, then "Waveform Only" will be your only choice here. With any media file except MIDI, you will see a waveform displayed when the sequence is opened.
If you have a Pro license, you can also choose to see the audio as a spectrogram (see the Audio Settings topic for examples). The spectrogram takes some extra time to calculate, so sequences will take a little longer to load (the amount of time depends on the speed of your computer and the length of the media file). For a 3 minute song on a fast computer, it should only add a few seconds to the load time.
This setting also impacts the Audio motion effect. If you choose "Waveform Only", then many of the options in the Audio effect will not work.
