The mysterious X strikes again. Every audiophile gathering has to have one it seems. Did you ever surmise his agenda? Another proselytizing guru by chance? Hmmm.
Videos of Acoustically-Coupled Audio Recordings

possibly not on a forum so was forced to say all he could about himself in one evening
I have not played the track on my speakers, I just listened to it with headphones.
I am working on improving my room's acoustics and waiting for a component change to my system - will resume recordings after, in a month or so.
If some of you are listening to videos on your phone's build-in microphones or on a laptop without headphones, I can recommend a "budget" headphone - the Sennheiser HD 400 Pro: https://www.amazon.com/Sennheiser-Headphones-Audio-Production-Definition/dp/B09K8VD926
It has a fairly neutral and extended frequency response, is light and comfortable.

I owned quite a few more expensive headphones (Grado, Senn, Dan Clark, Beyerdynamic...) and I find this cheaper model well suited for evaluating videos. I know it is not the most "musical" or dynamic but I find it is pretty neutral ("natural" sound). I really enjoy it. Have you listened to it?

Maybe he thought it was a meeting of Audiophiles anonymous.
Dont forget to add a bass driver as well
Ps if i dont see another Organ vid being posted im gonna record another one next weekend .
Talk less post more ( vids )
I ll make a vid tomorrow of the Church organ in Arnhem netherlands / CD.
I have heard many nice church organs in person. In both netherlands and belgium.
One vid with a closed speaker and one with the bass reflex pipe

Since we are back on the topic of organ music, and I am too lazy to check for myself the frequency response of my microphones, I looked for data online.
Regarding the Tascam DR100, the only thing I found is this post showing the recording of a frequency sweep with I assume the build in omni-mics:
audiosciencereview.com
As can be seen in the post, the drop at 50hz is due to the speakers/room modes. But below 50hz, there is a significant roll-off.
Here is a frequency response of the MV88 that I found here: https://www.soundguys.com/shure-mv88-video-kit-review-24578/
Here the roll-off is even more pronounced, and you would not know that from reading the specs (FR from 20hz...).
This does not mean you can't get a sense of the bass response of a speaker with a recording. It is just data to take into consideration.

Also, its a good idea to remind ourselves what various deep bass frequencies actually sound like, and at the same time, check that you can actually hear them with whatever device (hopefully - headphones!) you are watching these videos with.
Here is a Qobuz album with various frequencies: https://play.qobuz.com/album/dcon58qby5yxc
And on YouTube (check the channel for more frequencies):
I checked that my Sennheiser HD400 Pro does go down to 20hz as advertised (though of course there may be a roll-off, but I can still hear the track...).

This sounds good! I see it was recorded with the MV88.
I extracted the audio track from the YouTube video and checked the frequency spectrum:
Their is a good bass "foundation" on the recording, but I would be curious to know what track this is to compare with the original.
As you can see from the graph, the bass volume below 50hz is quite low, but I don't know how deep it goes on the original track (and maybe this is not even the proper way to analyze things).

the best headphones are the decent one's easy to use, so in the flow of your sessions, when a video comes up.....and......you actually use it. the pretty headphones and amps sitting 'over there' by themselves are not really doing the job.
i've seriously invested in top level headphones and headphone amps twice, back in 2010-2012, and then again 2 years ago. my aim was mainly doing justice to on line videos which i do enjoy. some system headphone listening too. but both times other priorities intruded and so i liquidated the spendy gear. and really never used those involved 'systems' for on line video's since just connecting them was too much of a pain.
i ordered these HD-400 Pro's 2 days ago (great suggestion) since they will be actually used (just plug into my laptop and proceed) and i won't be tempted to off them for another babble. thank you.
I’ve no clue how you reached such conclusions unless per chance like some others you too are relying on a friend. But I appreciate your dogmatism.
Below is a piece with enough bass and ambient info embedded in the recording, reproduced in the listening room, and then captured in this in-room video to convince me of the inaccuracy of all your claims here.
Even a tiny stereo condenser recording mic i.e. a Shure MV88 plugged directly into my iPhone 12 Pro seems to do a well-enough job preserving a sufficient majority of all that’s been captured across the entire frequency spectrum, uploaded, and then downloaded for playback. And there’s good reason for much of the fidelity being retained throughout the entire process.
IOW, if one is disappointed in what they hear then it's probably one of 3 things. Either the in-room playback presentation is left wanting or the settings on whatever one uses to record are inappropriate, but most likely a hybrid of the two.
But as with any playback presentation the listener needs to crank up the volume to at least begin to approach live performance volume levels.
Getting back to your post here - I found the track on Qobuz (note: the volume level on Qobuz is lower, so adjust it to compare): https://open.qobuz.com/track/161378867
Your video is good! Comparing the track with Qobuz, however, you can see (hear) that the lower frequencies are not fully captured, and that there is less intelligibility/resolution in the rest of the frequency spectrum, which is expected, to some extent, with recordings (even with a mic like the MV88) - whether that reflects what you hear in your room, I would not venture to guess!

Thanks. All of my videos are via the Shure MV88 as it's the only aftermarket mic I've ever tried. The MV88 seems to perform well-enough, it's essentially plug'n play after downloading the MOTIV sound app to my iPhone, and it's rather reasonably priced at $150.
But frankly, and as I recall from a frew years ago, surprisingly the MV88's resolution ain't all that much better than the iPhone's built-in mic. But it offers stereo and greater consistancy across the board. I've been using it for about 3 years now and have been more than satisfied since I never have to give it a second thought. So long as the config / settings aren't outta' whack.
As for the track info, the cd case is in storage but the title is Misty and it comes from an album entitled "Top 12 Gold Hits" from FIM. No clue on the artist.
I appreciate your pursuit here. But since after decades we've yet to discover the absolute best speaker, amp, cable, etc, and we've yet to settle on any such standards there, our pursuing a best mic is yet another bottomless rabbit hole. Of which the industry already has too many, IMO.
But if there is a standard worth considering, I suspect it would be how we listen to these videos. Hard to believe some are actually listening to these via their smartphone's built-in speakers or their desktop computer speakers and listening at volume levels significantly lower than perceived live volume levels. WTFrick?
I'm not saying we need studio quality mics...we just need to be aware of some of the limitations. A lot can be detected with pretty basic recording equipment, as long as we avoid really crappy recordings. But if something really catches our interest, a better recording digs a little deeper, but in no way could replace an actual demo.
Vis a vis listening, I agree. A video can sound very different when played on a phone's build in speakers and when using decent headphones...

When you record your system through the internal mic in the iPhone and you play it back at a certain volume setting on the iPhone, at what mic gain level do you have to set the app on the MV88 to approximate the same volume level playing back on the iPhone the MV88 recording that you hear when you play the internal iPhone mic recording back on the iPhone?

I just received the MV88+. I am returning the MV88.
Having the mic on a separate little mount (separate from the iPhone lightning jack) seems to be easier to deal with for me, as I am trying to settle on a tripod/ball-head/iPhone mount/microphone mount set-up for the Costa Mesa audio show.
I figured out a useful combination of adapters, mounts and gadgets:
