Videos of Acoustically-Coupled Audio Recordings

Another notable video of his is this all in one speaker by Cabasse for just 3000 Euro:

A full range speaker, should be er full range.
Full range drivers are not usually full range.
My iPhone's built-in speaker is a full-range speaker as are my Macbook's built-in speakers. My VMPS RM-40 speakers stand about 5.5 or 6 ft tall, weigh 240 lbs each and they too are also considered full-range. Yet, not one of them plays down to 20Hz.

The number of availabe true full-range speakers can probably be counted on one or 2 hands. And that's probably only true if their owners have achieved a rather superior speaker/room interface.

IOW, when it comes to speakers the term full-range is quite relative and subjective and very rarely genuinely accurate if we're talking the capability of producing notes between true 20Hz and 20k Hz.

Limited full-range is not too uncommon a term. But then again, I suppose that's like having a limited full tank of gas in the car.

Kinda' surprised that anybody in this day and age would get hung up on this presumably well-known loose play on words.

I have not had the opportunity to test my microphones, but from various specs available online, it seems pretty clear that reproducing deep bass response with the sort of recording equipment we use is simply not possible. So you can enjoy organ music at home, but don't bother recording it...

Bass reproduction is simply one aspect where YouTube videos fall short.

Ambiance is also probably very difficult to reproduce. Microphone placement here is key, and the listening position may not always be the best choice.

Low level detail is yet another aspect which will not translate well, as various microphones and ADCs vary on sensitivity...
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.

This is what I know:

- my Superlux microphone does not record below 50 or 40 Hz. I don't know about others, but I suspect many don't either. Please check out the specs before questioning my honesty ?

- with that microphone, distance to the speakers is key. Place it incorrectly and vocals, for example, can sound hollow. It could be different with other microphones, I don't know. You can find other testimonials from users regarding this point. Regardless, soundstage that you experience listening to speakers is difficult to capture in a recording (and that video you posted is not going to convince me otherwise). Moreover, listening to a recording with headphones introduces differences as well.

- microphone sensitivities vary and the results in terms of detail are obvious. This is a fact - again, look at the specs, or just listen to various recordings.

Maybe the Shure mic gives good results, I don't know. What I do know is that even basic microphones give widely different results, sometimes very good, sometimes very bad.

So maybe I should have been more cautious, but regardless, please tone down the accusations. Thanks.

By the way, concerning bass I clearly stated that my speakers do not do deep bass. I even showed the frequency response (perhaps not in this thread, though).

The level of detail I get from listening to my speaker is much higher than I get from a recording, and I suspect that is the case for everyone here. This is normal. If it were not the case, would artists bother using very expensive microphones in a studio ?

As for placement, I struggle with that (and I do think my ORTF mic is very sensitive to placement), but I am ok with the results of my recordings on that aspect. It is probably perfectible, I am not a professional recording engineer...

If I thought recordings were not useful in some way, would I record my own system and watch others'? I don't think so. My comments were just meant to be reminders that you cannot draw too many conclusions. For example, comparing some subtle changes in equipments (such as streamers) on YouTube is nonsense, IMO.

I don't know about "emotion"... That is not what I am looking for on a YouTube video.

This YouTuber provides good information in his comments. I liked his enthusiasm for the baffleless IO Design speakers.The quality of the video is decent. You can get a good idea of the difference with a typical boxed speaker...


And if you had bothered reading this previous post of mine you could have seen that I appreciated this recording (with a phone ..). It makes me want to listen to the system live! But only an idiot would purchase it based on the recording...
 
Regarding the Shure MV88 mic, it does seem to have pretty good specs, though actual tests may demonstrate serious roll-off starting at 50 hz (probably even above).

It has a number of settings (ex: angle) which can be useful.

 
One of these videos is recorded with the iPhone mic and the other video is recorded with the MV88.

This is the Vimeo playback interface.

I find really useful to go to a particular spot in a video for playback. That makes compares much easier. Put each video in its own tab or window set at the time you want to listen and easily switch between them. You can pick a time spot in vimeo full screen but less convenient to switch.

Were these recorded at different volumes?
Can you record in landscape?
 
Carole King "Tapestry" (tape)
iPhone mic

 
One of these videos is recorded with the iPhone mic and the other video is recorded with the MV88.






The second one has more distance ambience. The first one sounds front up and sonically better. Not sure which is more representative of in-room. Also, the question is, if you make a change that is audible over the video, do both suffice?

I see the primary advantage of the MV88+ kit is giving the MV88 mic access to Android phones.

The use of phones and microphones for making audio videos appears to be a burgeoning sub-hobby. The ability to parameterize microphone settings adding yet more variables to the production, making apples to apples compares across systems more involved.

I suggest creating a sub-forum for discussion of recording techniques, playback hosting, etc. The idea of standardizing video recording has a strong appeal.
 
I will be uploading a bunch of Munich show videos that were done with a Zoom IQ7 plugged into my IPhone. Will be curious the opinions. Bass seems good on my videos

Did you record any of the same track on the same system both ways for a direct comparison?
 
I have a feeling you recorded this one too loud ?

I don't know what "too loud" means here. I record them at my actual, normal listening level, which is about 83dB to 93dB - 95 dB on peaks.

Is the internal iPhone mic being overloaded here?
 
very possibly. I record them at my actual, normal listening level, which is about 83 to 93dB -95 dB on peaks

Don't know about the iphone's internal mic characteristics, but unless you use a special app where you can reduce the gain I think that volume level will cause clipping/distortion. That's what "too loud" means. With the Shure app, you can see the recording levels so you can adjust the volume more easily.
 
To equalize the playback volume on the iPhone of the two mics I had to turn the gain on the MV88 controller app all the way to maximum. Stenho suggested 24dB or 25.5dB but I had to use 36dB.

Unless I set the MV88 gain to 36dB the playback volume on the iPhone was too low.
 
There is a pronounced channel imbalance on the second video (right channel is muted). Makes the comparison difficult...

I think I'm not hearing a channel imbalance.
 
Were these recorded at different volumes?

The playback volume from the stereo itself did not change

Can you record in landscape?

The main iPhone microphone is at the bottom of the device so recording in landscape will emphasize one channel over the other.
