Share your fab capture - always interesting to hear!

//

my masters are buried in storage while we’re building the house, won’t be unearthed until spring. Never said they were fabulous! decent for amateur though. I need to get back into recording.......there’s a ton of great local music in this area.
Problem is telling the wife most of my recording equipment is outdated (the marantz digital recorder I have has like a 1.2 GB capacity no matter how big a card you put in it) and needs replaced right after a major home system overhaul !
I’ll get them on here eventually! :hphones:
 
The real problem I see with the RNM tip is the mike used.
How dare you call something done by RNM a "problem" after posting something like the one quoted below?
Sorry to say this, but you are insulting somebody which is a lot more equipped, passionate and experienced in measurements than you seem to be and will never be.
Not to say that you are boring like a striped record of a Lady Gaga fanboy, which you clearly share the mode of intellectual functioning.

If I can give you the advice of an old Indian, remove your filter of odd harmonics and your prejudices about things and people.
And you've been critical of the tone of the post by others on this forum. :scratch2:

The equipment is accurate (speakers also not bad), but the speaker room interaction is always compromised IMV
More that in your view, it's universal, as confirmed by measurements.
 
Wish I'd still been alive and there when this was recorded, would have been a good test.... YouTube

Actually this one has much better sq to me than the one you posted, but these old recordings tend to have that syrupy wet blanket sound.......not that it’s a bad thing but certainly not to be confused with what it actually sounded like live.YouTube

Have heard enough New Orleans style jazz live to be able to make that statement with a little bit of validity.

I actually like the old tone as long as it’s not degraded (scratchy etc) and many people try to recapture the sound but I’ve not heard any that were too convincing......anyone know of some that have succeeded in doing that?
 
J.C. seems more interested by transparency and euphonics, of course, SW by performance, Bonsai by neutrality, Syn08 by its glory.

What the **** entitles you to guesstimate, without any factual support, what others appreciate (or not) in sound? Gloss as much as you want about your own hearing and preferences, but leave me out please.

As a rule, it is considered rude to mention somebody without context or net contribution to a discussion. I could post in the Construction Tips board something like "everybody knows T-E is as deaf as a block of concrete", would you mind that?
 
Just read the RN speaker test. I guess hes never recorded a voice before. Take it from some one whos tried to match hundreds of actors voices to there production dialogue, recording ADR. The mic, its angle, position, pattern, distance, and the room all sound different. Even the persons mood can change the sound.
 
Speakers are very subjective

And rooms are very different. When one moves his listening equipment from one location to another, one often has very bad surprises.

My big system is...big. Horn, directional, don't excite much rooms resonnances in the middle treeble, contrary to the KEF.
Comparison is unfair; but my big system is the one I'm used to.

My actual room is way toooo much bright, so, I think, emphasis a lot the defects (fracioning peaks) of their bass (?) medium speaker I can hear.
So, my critics have no universal values, I can understand you can appreciate them.

The focus of the heights, onces aligned, are exceptional and lot better than in my big*. But, as the rest of the spectra is well under, it creates an annoying imbalance in my ears.

Whatever we could try, no way, even with a sub, such a little enclosure can mimic the real energy of a drum kit, moving enough air.

* My big is very natural, nothing shining. Same compression driver for 1K-16K flat with no extra tweeter. Most of the audiophile looking for effects would not be impressed. ;-)

I think you misunderstood his purpose. The idea is not to drop your recording with no audible change, as we try in ADR, but, closing your eyes, to feel if something unnatural can be noticed, and if you can fool yourself that your friend (or whatever) is live in your room with no PA. (near impossible to achieve)
The previous direct listening while recording is just to refresh memory of the real thing.

An other useful tip is to record ... your speakers with a music you are very familiar to. Antidepressant recommended.

Recording your own live sounds is also a good way to judge your gear... You were there and so you know what it should sound like. Not unlike the process I described for in-home audio eval for accuracy.

Its what is behind my process, i did my own recording ... Revox 30 ips half track set up for using Ampex 456 Grand Master tape. Condenser mics... best sound I ever heard played right off your master tape. I would put it thru an inverse RIAA filter and run it thru the phono stage to listen for its' sonic accuracy. But need to be near-field or the room will distort the sound from what it was at the recording site.

recording in the same space/room as the playback makes it easier to know... dont have to try and remember the sound when recorded. Can do A - B comparisons in near real time.

Just get a great Omni... measurement mic of high quality. Record close to mic... not on top of it, just close... a few inches. No room pick-up. Your ears will do the rest.

Not really. As before, mic, angle, positon, etc all make a difference. Mic a few inches from what? ( you move a close mic on an acoustic guitar an inch closer to the f-hole youll get more low end). Most instruments produce different sounds in different directions so to hear them realisticly you and your mic need to be a few feet away, do you listen to a violin 3 inches away from it? Try this. Record the same person from 3 inches and 6 feet than listen to them, theres a lot more to the difference than the room.

Well, it depends on the size of the room.

I have a fantastic Bill Frisell recording (his recordings are always good - outstanding musician as well) and the drums are always well mic'd up.

The clipping indicator on my big amp flashes at 57.8V peak. That's the equivalent of ~200W which is what was going on with the KEF's paired with a sub bass. They can soak up a huge amount of power and deliver some serious SPL's - but granted, this was in a moderately listening space (my living room).

The best imaging Ive heard - provided you are positioned correctly - has been from horns. But they can also sound 'honky' if not done right. Excellent for acoustic, jazz and opera IMV. There's a company about 100 miles from where I live that make 200 grand horn systems Living Voice Vox Olympian/Vox Elysian Speaker System - The Audio Beat - www.TheAudioBeat.com.
