A while ago tjcombo posted this image of the spectral plots of various instruments playing concert Bb, as given by the freeware programme Audacity.
Well, I downloaded Audacity, got it adjusted to what I think are the same settings and tested it on my menagerie. Same concert Bb, all at similar volume and same mouthpiece (DW 2W). Surprised (a bit) at the differences.
Does anyone have the faintest idea what sort of conclusions can be drawn from plots like these. Gut feel is that any peaks below -48dB and beyond 10,000 Hz may be irrelevant. But I can't help sort of liking the look of the plot for the Wild Thing. I am getting on pretty well with that instrument at the moment.
