It would be great if we could sync our Nanoleaf products to music playing on computer using the Nanoleaf Desktop app; or coming into the computer via a line-in. This would be a bulletproof music sync solution for the newer shapes range which do not have a 3.5mm jack like the rhythm module does.
I think what they mean is the system could act like an equaliser. The desktop app already provides "visualisations" such as the Screen Mirror effect for displays.
Alternatively, an Audio Mirror feature could be added to support direct sources. For example, input from a musical instrument (such as an electric guitar or keyboard) could be output using a Nanoleaf kit.
