Whatever, but I was specifically referring to the tendency of people nowadays to refer to ALL signals, analog or digital as “data”. In the context of audio electonics design and audio reproduction in particular, labelling a purely analog signal as “data” is a misnomer.

I can see instances such as yours in research when analog signals are broken down into “data points” for statistical analysis. When analog measurements are presented in a graph, that is “data” – the paper presentation is the “data”. However, when an analog signal is not analyzed, but is mearly being routed in an audio system, to be listened to, it is not called “data”. The term “data” in the context of audio reproduction is taken to mean a digital stream.
