Videos of Acoustically-Coupled Audio Recordings

[tima]

The process you describe records only the power delivery, the LP, cartridge, arm, table, phono, cable and ADC. It cuts out contributions from the amps, subsequent wires, speakers, and room. If the vinyl front end it good, we should get a good sense of the sound of the recording. It is interesting, but it is not the same as comparing whole system videos. This might be interesting to compare to the digital "official" YouTube release of some recording because of the lack of variables, but it is not apples to apples with most of the system videos on this thread. It does sound good though.

Change the thread title from "Videos of Acoustically-Coupled Audio Recordings" to

Whatever the approach and method used, there will always be objections, whether it relates to the type of music used, the source, the microphones...

I give up!

our point is that it is not a system video any more than some YouTube official digital recording.

it is not a video of what the listener hears in the room. As such, comparisons to system videos don’t tell us much.

Still managed to be more interesting, productive and on topic than the last few pages of discussion IMO.

You can only come to this conclusion if you don't follow the thread closely. What you don't seem to do post 1,793. Please to you and tima. stop writing in such a condescending manner as if you are the authority everyone must bow to.

Given the thread title it doesn't seem unreasonable, does it?

What is the purpose? What is the goal? You pulled a recording coming off a phonostage into a DAC. It was pointed out that approach did not seem relevant to assessing system videos. Is that a legitimate observation?

I believe what you really want to do is compare you tube videos heard through headphones, regardless of how they are made, to system videos, and pass judgement one way or the other. Is that what you want to do?

Earlier you wanted to talk about objective assessment of audio systems without using measurement. And you think that by using you tube or streaming service audio for comparison to system videos it becomes objective. Is that what you're after?

Sorry, but I'm confused.

This is a thread about videos acoustically-recorded from speakers. What's the point of posting a video which simply illustrates an ADC dubbing process?

The process you describe records only the power delivery, the LP, cartridge, arm, table, phono, cable and ADC. It cuts out contributions from the amps, subsequent wires, speakers, and room. If the vinyl front end it good, we should get a good sense of the sound of the recording. It is interesting, but it is not the same as comparing whole system videos.

It does sound good though.

Dasgiteohr, Ron expressed confusion and I tried to explain how I understood the elements of the video. I’m sorry that you find my explanation to be condescending. I assure you that I am no authority and no one pays any attention to my posts anyway. How is my tone any more or less condescending than Ron‘s in his post just before mine? He and I basically reach the same conclusion.

this thread has been full of different suggestions about recording standards, playback standards, reference standards, and feedback or opinions on the quality of posted system videos.

I'm not understanding what you are saying. Could you please connect your post 1793 to what your are saying about not closely following the thread? What is being missed in the thread that would lead Peter to his conclusion. ... which I share?

Hopefully it not condescending to quote you and ask you what you mean,

Peter say it's about system video. I am posting a video(post 1793) on the subject. They argue what feels like 10 pages about David. On 2 pages we talk about how you can display the sound of your system more realistically. Microphone and recording technology is perhaps not bad to read carefully. Maybe there is a tip that will help you with videos if you want to post more. I just say swarm intelligence. Goodbye here

” Peter replied to you on this and I endorse his reply. What I don't understand is why this is important to you? If David was still participating I doubt you'd be so casually brazen.”

Do not be too hard on them @DasguteOhr , they haven’t been quite themselves since that trip to Utah :

I haven't measured it, but I have to set about 10dB less volume than a Samsung mic, so it's more sensitive. I used it to measure Xover for speakers. with the Microphone+ Audiotool app. It was checked very carefully with a 94 dB (400 Hz, 1 kHz and 10 kHz) test tone generator. it passed with flying colours.
I didn't notice anything unusual in terms of sound

P.s 10 steps less khozmo controller 10db

I recorded a track with my Umik measurement microphone connected to my Android phone, and I did not like the results. There is a drastic loss of resolution in comparison to the Superlux S502 + Tascam. Perhaps I did something wrong, I don't know. I may try again using a laptop instead.

Listening through headphones has the advantage of not imposing a second room reverberation on the sound you are hearing. Whether playing a ripped LP or an originally digital file is more representative is debatable but either will give a good idea of what the system should sound like. Comparison will allow one to hear where one’s system deviates from that recording. That is a relatively objective approach to determining fidelity of a system. Realism ultimately depends on the recording quality.

follow the instructions here, should also work for your microphone.
once the calibration file has been properly loaded. the microphone is recognized immediately when plugged into the handy or tablet.
at least that's how it is for me

The calibration is not the issue. I recorded audio then applied the calibration to the recording in Audacity. I'll try AudioTools, but I doubt it will make a difference.

No, no, no; don't give up.

No matter what you do, there will always be legitimate technical and practical criticisms. The crows will peck at you from above. That's totally fine; that is the nature of crows. You can cheerfully ignore them.

If you choose to standardize to a particular microphone and a particular protocol, you have to draw relatively arbitrary lines somewhere. I have drawn the line with an external microphone which does not have to be plugged directly into the iPhone, and which I can EQ to achieve greater representativeness of the tonal balance I hein the room.

I have adopted a simple external mic, which does not require phantom power, and a tripod and a mounting set-up which is quite portable, and I have drawn the line against a full-size studio microphone and phantom power and multiple microphones and a dedicated video camera and other possible complications in size, power and complexity.

My set-up is now fixed. I am confident it is superior to the internal iPhone mic, and I am happy with its sound and with its portability.

PS: The only annoying part of this process has been ordering and playing with half a dozen different adapters and thingamajigs to connect in a sturdy way my Benro tripod to my iPhone, with a mount for the microphone.

Okay - your reference for assessing an audio system is a digital file played through headphones. Are you inclined to have that as your primary approach for reproducing music?

I was thinking something a bit more along these lines...

 

[stehno]

A good vinyl rip will sound natural over Youtube but the original recording has to be great to sound as realistic as this:

Well..., not quite. You're not even including the level of musicality that a playback system contributes to the final presentation? Seriously?

If given the choice where I could only have a superior system or a superior recording, hands down gimme the superior system every time. Granted some may see it as a, which came first the chicken or the egg but I don't think so?

I routinely hear inferior-engineered recordings sound way more musical than perhaps they ought when a system is well-designed. But I don't recall a single instance where I heard a superior musical playback presentation when the recording was superior and system inferior. Have you?

You mean would I take the saxophonist/Youtube playback via my phone over your playback of Way Out West (wav) in your listening room. The answer is a resounding yes!
