Anders,
You seem like a technically openminded person and perhaps one more interested in objective testing for comparing violin sound quality.
Let's say you wanted to 'objectively' measure how well two violins generate and project frequencies in a perfect fifths ratio [3:2]. Where would you position the mic(s) and what other
equipment would you use to narrow your measurement to fifths only? Also, would glissandi be a sufficient method to exercise each violin??
Thanks,
Jim
