May-i report a personal experience ?

When my son was young he manifested the desire to have an electric guitar.
So I bought for him a little cheap chinese copy of a fender Telecaster on a web site and we visited a friend that I take as one of the greatest guitarists I had met.
Despite the guitar was too little for him, not the string's gauges he prefers, despite he was the owner of some of the best guitars some can find, he made to him, in 5 minutes of pure tenderness with this baby guitar, a demonstration of near all the styles of rhythmics and solos that exists. RnR, Hard rock, Blues, country, West coast, Folk, funk, RnB, Jazz, reggae, slide, fingerpicking etc.
So groovy, so intimate, I will never forget. He was just like a phaser putting his son on his first bicycle.
My son told-me last week that he was so disgusted to had never been able to even approach no one of those sounds.

Tournesol,

A nice story. Your friend will have an intimate understanding of how a guitar, in fact any guitar will sound, and all that muscle memory will quickly enable him to adjust to a cheap guitar fresh out the factory and play it like the virtuoso he is. This is why it is so important that all guitars regardless of their price or value, are set up properly. Tell your son this, and if the guitar needs a set up and gets one, it will make playing a lot easier for him.

Great, so the problem was addressed. The original Zung statement is then false (can't read the article beyond the pay wall).

syn08,

The value of a high priced acoustic instrument is mostly due to how it sounds to the musician playing it - not the audience.

For example, there are only 27 Stradivarius violins left known to exist. Each have their own unique sonic character, and in the hands of a lesser player some are almost impossible to play. All of them will sound fantastic in the hands of a gifted player. This is because that in the right hands a great violin will open up a zone of creativity not possible in a lesser instrument. The audience is not so much aware of the tone of the instrument, but the intent of the player.

It is that intent that opens up the music for the audience. The violin is what facilitates this, and is partly why they cost so much.

A great violin will always sound mediocre in the hands of a mediocre player.

This is the very common confusion between an identification test and a preference test. I never said a FFT measurement could up front find what a musician prefers.

That's a gross over simplification, worthy of an EE: measuring the harmonic content at one single instant "t" and call it a day. You may be getting there if you included all the slices of time from before the bow strikes until well after the last decay, then do it all over again vary the force of the bow.

Btw, I had been an EE too, but I know and acknowledge the limit of engineering... :)

From an (even former) EE, I would expect to know that a Fourier Transform can be applied only to periodic signals, or signals that can be extended to a periodic signal. Therefore, there is no "t" measurement of a harmonic content. Non periodic signals are handled via the Laplace Transform which has little to nothing to do with Fourier.

The definition of "periodic" is non limiting, though. You could even consider the periodicity of a song played in a loop, as much as a string plucking, played in a loop. In fact, this is what I would do if I would have to analyze a string instrument spectra.

There is a big difference between attacking and defending himself against a personal attack. Once the war is initiated, victims are both side because arms are both side the same and the field chosen by the attacker. Some are strong enough to hold the other cheek, I apologies to not be strong enough. As an effort, I will keep-you back in my ignore list.

I also notice that every time I try a gesture of appeasement, it is received by a barrage of artillery.
Beautiful examples in the above.
You will have to quote the particular writing, especially when you say "above" after claiming the quote below. Otherwise the readers will think you are referring to the post by PMA, mountainman bob, tapestryofsound, Zung, billshurv, chris719 or your own.
Oh, please, he his in my ignore list and he knows-it. I only read-him when he is quoted,
 
Tell him about the Heritage Guitars. Built by hand with the old Gibson tools in the old Gibson factory, I consider their H-535 as a much better "original" version of the 335.
Thanks a lot, Zung, i will ask him, but he surely knows about them. He has a real violin workshop in his house, guitars in construction everywhere. All his guitars, including his old 335 have been permanently polished, improved etc.
He is able to order old stocks of wires for his humbuckers at the other side of the world. He also has an astonishing amps collection: He eats pasta at all his meals and does not get warm in the winter ;-)
Talking of passion for the music and instruments: I have rarely seen him without a guitar in his hands, even when watching a movie on TV.

“bout old recording.
In the 1960s and 1970s, tube technology had reached heights. And the euphonic quality of some microphones (Neuman U67 for example) remains unmatched today: They are still used as pearls in a lot of modern studios.”

I agree. The best recordings I have are from the late 50’s and early 60’s. There are some real modern gems as well though - Yo yo Ma for example
 
Yes , like just now I wanted to respond to both you and Jakob in one
Aha
Look at the quick reply box below, it is the most-left icon there and you'll find the same in the row of icons above the text box when replying after pressing the "quote" button.
Aha

Use the multi quote button just to the right of the quote button on each message you want to quote before hitting the quote button
Aha.....thanks guys
 
Thanks yet again, Markw4. I need to know the problem areas, if I am to address them. Of course, analog is relatively easy to 'improve' but it is not enough. Power supplies can be dealt with, but other digital based problems are a mystery to me.
Video Killed the Radio Star.
I'm more or less in the same situation. Like, I believe, a lot of us.
But it is exciting to get a new territory to explore, don't you think ?
We definitely need an help from Markw4 on the best way to begin, what to look-at for what results etc.
May-be it would be a good idea to open a thread on this purpose ?

This might be a typo?

Fourier integral transform works above a function that is continuous in time domain and the result is continuous in frequency domain. No periodicity requested.

Fourier series works above a function that is periodic in time domain and the result is discrete in frequency domain.

Discrete Fourier transform is periodic in both time and frequency domains.
 
When it comes to aural memory, it's fresher the better. So your thinking is wrong.

You're right. That's the 'little benefit' I mentioned. ;)

"It is not little!" you might respond in disagreement. Well, if someone is relying on the fast A/B switching feature of FoobarABX, he won't perform well.

For example we have one.wav and two.wav. I can play one.wav several times to get used to it, then I play two.wav. Once I know the difference, I can ABX the file by playing only X (or A and X). If I play A I will know if A is one.wav (or not) then I play X and I will know if X is one.wav (or not). Then I don't need to play B and Y to give my answer.

Do you know how it is possible to give answer by playing only X?
