 Once the frequencies have been binned per frame and stored in a cache, the result of the FFT is deleted. The audio file is ready to be used.

+When either of the plugins are used in Modeler, a fps of 30 is assumed since the scene fps is not available. This may affect loading a motion path saved in Layout to be used in Modeler as well.
+The fps is used to determined the number of spectrum samples stored in memory per second (one set of samples per frame). If the fps in your scene is different, the result in Modeler will be different as well (especially if interpolate is off).
+In that case, baking in Layout is the only way to get a 100% accurate representation.

 This will load the currently selected audio file as the File used in Layout, allowing for playback of the audio file.
-This will not work for some types of audio files, Layout seems to only support WAV and MP3 at 16-bit.

-Similar to **Frequency (norm)**, this input actually used the Octave bins as opposed to the frequencies. This will lead to a much more pleasant distribution if it's used to colour items based on an index or displace vertices depending on their position.

+When there's strange audio playing back in Layout, such as while using DB&W's Audio Frequency Node, you're hearing (apparently) your computer's fluctuation in processing time from one frame to the next and it can be fixed by opening the global Properties panel, selecting the General tab and clicking the "Play at Exact Rate" parameter's check box to an ON state.
