He also reported the following: "if I rig up
a TRRS 3.5 mm jack to XLR

with other
issues, perhaps ground loops or impedance mismatch or something)".

On the software side, couldn't a sample rate
conversion produce that
kind of
pulsations? I'm not doing any, but I haven't checked Android sources
about this.
I don't have knowledge about this and at the moment I'm a little bit
pissed of all the issues we could get, when using the computer ;).
I tend a little bit to prefer analog equipment at the moment, but your
noise issue could be an anlog issue :D. Regarding to this or similar strange pulsations, I
heard this for
recordings done with cheap consumer microphones and cables using analog
equipment.
No doubt, there are all kinds of issues possible, regarding to the
digital domain, but this noise or a similar noise is something I *very
often* heard for recordings done with (very) cheap consumer equipment.
Okay, that's precious informations. I wasn't sure this could come from the mic,
but you're making it clear that it's much probable.
By the way, this is all about low-end (or very miniaturized) stuff, but also
real world: a lot of musicians find it handy to have a recorder in their phone.
Of course that's more about recording rehearsals than concerts.
