The irony of playback photographs and videos.
fiogf49gjkf0d
I find that to look at the specific components photographs is useful to see the new TT design or hew horns shape but generally photographs of the enter demo rooms are absolutely worthless. Over the year the audio people make a fashion to make video of the turntables spinning, the room playing. I always was in disgust to learn about those videos – how much more moronic could it get? However, in contrary to my detested the demo room video I have to admit that they much frequently then not give a more or less objective idea about sound of the room. Of cause all phones are different and there is no common recording techniques how people record the videos.  Still, as many video clips I have seen as many times I was able to hear the very obvious problem of the given setup even over the horribly recorded videos.

For sure the absence of auditable problem on video clip is not an assurance that the problem exists. However, if you do hear the problem on video clip then what change is that the problem does not exist in real life?

Just for an illustration try to listed the crap like this:  http://www.youtube.com/watch?v=ALsEVY57CGg

The videos reveal a lot…
fiogf49gjkf0d

In this particular case we can very easily judge the quality of the microphone, because the guys are talking and their voices sound OK – quite in contrary to the absolutely disgusting sound of the "violin", coming from the "loudspeakers"…

Here is another example of super crappy sound (do not listen to it - it is real punishment!) : http://www.youtube.com/watch?v=R1Segwsslno&feature=related

Wow, I have never heard more colored and resonant midrange!

I see only one problem with all the videos - there is no way to understand how well the drivers are integrated...

Might be we all try to do it?
fiogf49gjkf0d

Yes, Haralanov, you do pay attention to the right things. I use to write about this room in Moscow. The guy talk about a lot of things with pretentious attitude but one single look at his listening room turns me off instantly. It is for sure a wonderful home and a wonderful room but looking at the distance and the acoustic treatment of that almost glossy room it is very obvious that anything coming from there is in pure realm of fantasies. The link comes from here: scroll doe to the bottom to get more video clips:

What I think in context of video clips: how about we all upload short video clips of our playbacks recorded from listening locations via telephones? I would be less interested to see the videos but I would be interested to hear the playback owners comments about own sound and to correlate to what we can hear on the video clips.

In defense of the phone people.
fiogf49gjkf0d
With all honesty and with all my agreement to what Romy and Haralanov said I have to confess that they are a bit full of shit. I desisted to make an experiment and recorded on my phone the video of my playback and then listen to the sound I got in the video.  I shall not mention that I have no overly reverberant room, no disgusting sound and no colored and resonant midrange. However, listening my video I got an absolutely revolting sound. I recorded with my LG phone running WinPhone 7.5. I do not mind to upload the video to my site in order everyone witnessed that it is absolute garbage in fact much worse than the video videos that I have seen.  The moral of the story is that I guess we need to judge slowly….

But why to use a phone as a recording device?
fiogf49gjkf0d
I agree that using a phone to record the sound of your, mine or anybody else's system can lead to very bad recording. But why to use phone? It is 2012 now and everybody have good digital camera. You constantly mention that you have very frequent visits by some “local guys” – I think at least one of them has good camera with relatively good microphone. You can borrow the camera for several hours, put the camera on your listening chair while talking around your acoustic system. If your voice sounds quite good, then we can (at least relatively) judge the sound of your Macondo. I’m very curious to hear how it sounds!

Hm, honestly I never thought about it. It is 2012 now and neither I nor anybody I know has good digital camera and everyone use phones. For sure if intend of a phone was a dedicated camera then the result might be very positive but I think that all videos that we see were shot by smart phones. Anyhow, the idea doe not repeals me and if I have an access to a full function camera then I might do it.

Not kosher.
fiogf49gjkf0d

A site visitor sent me a link to the “sound” of video playback that is very good.

http://www.youtube.com/watch?v=uwb9OCivhtg

Upon looking the video I realized that as camera moves the sound does not changes, so the sound was not recorded “live” with microphone but was overlaid by post-production. This is not kosher at all. I think if sound is not recorded by on-camera microphone the video of this type has no value, at least in context of this thread. The post-production writing of sound from line level is not the sound of the speakers or a given playback but just sound of line-level signal.

Cat, I'm saying it officially - you are DEAF!

Pull out the cotton of your ears and listen to the video again.

I do not think that sound changed. Those speakers have most likely MF compression driver with horn. When the camera shot from the back of the speaker the sound does not change. I mean is changes slightly not where how it shall change if to locate a microphone on the back of compression driver. So, as far as I concern sound does not change and does not synchronized location-wise with what camera does.

I hear "room" sound and tonal changes
fiogf49gjkf0d
Could it be that the sound is somehow equalised and compressed by Youtube?
There's an obvious sound change at min. 3:30 but it should be more pronounced.

I think it would make more sense if we were to upload a 16/44 of our system playing the same recording made with a measurement mic.
That way you'd really be able to assess the bathroom-like quality of my living room Big Smile

You people do not get it.
fiogf49gjkf0d
I am surprised with all your reaction to my comments as it looks to me that you do not get what I am saying. There is absolutely no need to listed if the sound changes or not. The “sound changes” is not the fact that is under discussions and of cause something is changing that sound. The point that I am making is that sound in the clip does not change in according to how it shall change. This is narrow horn compression driver and he walk with his camera being the horn in the zone that shall be in absolute acoustic shadow. The sound doe not changes. Well, it changes slightly but no near how it shall. This effect wools be possible ONLY in very very-very room, but still not to the degree that I presented in the video.  It is possible that they used a remote microphone in the camera and the microphone was hold by another person in more of less favoriteable location. For sure it was not the microphone positioned on the camera.  I do not have a full scope camera but when I did the same experiment with my horrible phone-camera (walk behind the speakers) then the rate of the change was much-mach deeper then what is presented above. Walk behind your own speakers, and particularly if you use horns, see what happens. If you have the same “sound change” and the guy presented on video then good luck to you…
