Could resonators get aligned by air waves?

[Ruphus]

I´m adding samples to some acoustic rags in the box.
You certainly are familier with that phenomenon that you can easily have a sound in its vibration rhythm to be running against another source until you slip back or forth for a very tiny amount to match phase somewhat, which helps it parallel much better or even swing in great.

My idea is that one had much less of that problem with live situations where the waves / sounds rhythms seem to meet easily.

Could it be like say if you had a signal already in the room while you hit a string that the room signal would slightly influence the generated string sound so that the two matched halfways in vibrating rhythm?

I mean we commonly know already that passive strings and skins will reflect external sources if just loud enough, but could this slight passive effect be enough to help aligning a fresh and bold tone that you pick at that string, so that it would get in rhythmic sync with the previously existing tone / each other?

If not why then seem resonator sounds in rooms to match much easier than "dead" signals? ( meant apart of players aligments and harmonizing anyway )

Not an important question, but it had me wondering for a moment.

Muchas gracias for your wisdom, seniores.

I'm not sure what you are talking about exactly....

I think you are asking about how beat-frequencies develop on recordings, but don't seem noticeable in real acoustic spaces.

In that case, add reverb. The reverberant field (real or simulated) integrates the frequencies over time. Throbbing frequencies that are out of tune are smoothed by addition of the reverberant signal (at various phase, delay, and level).

No, what I´m trying to say is that recorded signals seem to have more rubbing points = you need to align them by ear to make them fit in regard of the rhythm of the tone.

While live signals in the same time seem to align to each other easier ( almost by themselves as long as the contraries aren´t just too much ). So, I am wondering whether ...

For example if you had a steady signal coming from a signal generator through your speakers and next you went and picked a guitar string in the same room. Could it be that these two signals would fit to each other easier, because the sound coming through the speakers would "warm up" the guitars resonating / swinging parts, respectively have influence on how the coming guitar note will be fitting to the generators tone rhythm.

You know the vibrating rhythm of the speaker infecting the guitars tone rhythm so that they will finally be relatively close and fit into each other.


Err, know what I mean?

I think you need to make a distinction between signals that are misaligned in time so that it affects the rhythm (swing) and those that are misaligned in time so that it affects the phase (beat tones)

I think in the case of the former, that live performances don't have this problem because the musicians are playing together and reacting to each other. When you overdub the communication is one way. The overdubber can react to the track but the track can't react back to him. This problem only gets more difficult as the tracks build up.

If I understand you correctly you are proposing that sympathetic vibrations between the instruments would help them to oscillate in lockstep. I don't think there is enough energy in these vibrations to account for a difference in live vs recorded music.

Take a piano and step on the sustain pedal. Now have someone slam a loud chord on a nearby guitar and stop. Sure the piano will ring on those notes, but how loud? couldn't the piano player totally overwhelm those vibrations with a chord of his own?

As tiny suggests, the reverb may be smoothing things out, and maybe there is some reason why real reverb in real time might be even better than artificial reverb at this.

That is exactly what I was wondering about.
The vibrations influence should just be too weak to have such an impact on the newly generated tone, but when I think to the differences with live tone merging ( even when the players / sources aren´t doing that good to explain the better fit ) then I ask myself whether the mutual influence of resonators could be more than one would expect.

I doubt it. I imagine that the phase relationships are just as random in live situations, but you can't hear it very well in the reverberant field.

Very interesting and sounds quite plausible.
Thank you for the idea, Tiny.
