A couple of months ago I posted a write-up where I identified spectrogram (i.e., frequency spectrum vs. time) features that were common to resonator guitars and absent from normal flat-tops (resohangout post and the write-up). My latest follow-up is Resonator Guitar Synthesis, and it provides some confirmation. I added a handful of sine waves to the sound of a flat-top pluck with frequencies, amplitudes, and decay times typical of the "extras" that appear in Reso spectrograms. (Each reso is different in detail.) You can listen to a sound-file version that total waveform. I sure think it sounds like a reso. Interestingly, when you crank up the volume, the added sine waves just by themselves sound like a crappy gong.
These extra features in the sound have frequencies that are unrelated to the string harmonics. Although weaker and shorter-lived than those harmonics, they are strong enough to hear.
These are the single pluck sounds: reso pluck, flat-top pluck, flat-top + synthesized extras, a single sine wave, and the set of sine waves used to turn flat-top into reso, amplified to be clearly audible by themselves.
(Even more recently, I looked at the spectrograms of a wood-body biscuit cone guitar. Of course, they had the same sort of extra features [with whatever cone alternative I tried], but you guys knew that. They've got twang. Those unsurprising details will appear on my Web site, Banjo Physics 411 AND Resonator Guitar Physics 412, in due course.
