How to AudioSource.GetSpectrumData while muted?
I'm writing an audio visualizer, which works fine. However, it needs to work even if the AudioSource is muted. But when I mute it, GetSpectrumData no longer returns any data. So I need sample data that isn't related to the current volume. Does anyone know if there's any way to do that?
Thanks!

Make an audio mixer, and add one sub-group within it. Set the AudioSource to output to the sub-group. Expose the sub-group volume to scripting. Then "mute" the AudioSource by setting the volume of the sub-group via script. The played audio will change, but the GetSpectrumData will remain.
(Note that if you're looking at the mixer editor, the master levels will fall with the sub-group, implying that the spectrum data would be changing. That is not the case.)
