I will tell you the lies and high resolution truths │ What is high resolution?
How is it different from a CD?
They often ask me, so I will answer first.
Does the high resolution sound source really sound?
Something good even there
What is the difference between high resolution headphones and those that are not high resolution?
There is no difference, the high resolution mark on the headphones has no meaning.
Sometimes
“Use high resolution audio equipment for high resolution audio sources.”
Listen to that.
This is a lie.
I affirm.
Strictly speaking, there are no audio devices that do not admit high resolution. (Excluding digital scenarios such as DAC and PLAYER)

Does high resolution sound really good? Those who suspect
What is high resolution in the first place? Those who say
All high resolution is hidden! Some people say that.
However, if high resolution does not make sense, that is not the case.
It’s just a personal opinion.
Of the conclusion
The high resolution analog scenario reproduction device is a hidden.
High resolution audio sources are certainly different, whether you can notice the difference or not. It makes sense.
Well, I’ll explain it to you.
What is high resolution in the first place?
What is high resolution in the first place?
Let’s look at authorized persons and general definitions.
View of Sony, a leading expert in high resolution
Sony was the first to say high resolution.
As he has seen, that high-resolution mark is a trademark of Sony.
↓ It is a mark on the top left. An example is Yamaha.
High resolution brand example
Let’s look at Sony’s explanation.

Short summary
The amount of data that can be recorded on a CD is limited.
High resolution can record even sounds that do not fit on a CD.
High resolution is approximately 6 times more information than a CD.
The CDs exist for quite some time.
Is it really obsolete in the digital world?
But what is high resolution? But I do not know the strict definition.
General definition of Wikipedia
Wikipedia is not always right, but it is often not out of the ordinary.
Now, let’s ask the Wiki teacher.
Specifically, one of the sampling frequency and the number of quantification bits exceeds the CD-DA specification (44.1 kHz, 16 bits or DAT specification (48 kHz, 16 bits)) (and the other also exceeds, or the same. Grade ).
Quote: Free encyclopedia “Wikipedia”
In other words, if the amount of data is even a little greater than that of a CD, it means high resolution.
That said, I do not think the SACD and the DVDs are called high resolution, so I think it’s a bit different.
High resolution definition in Japan cited by the Audio Association of Japan
Next, let’s look at the opinions of Japan’s audio association.
<Analog system>
(1) High frequency performance of the recording microphone: 40 kHz or more is possible.
(2) High frequency playback performance of the amplifier: 40 kHz or more is possible.
(3) High frequency playback performance of speakers / headphones: 40 kHz or more is possible.
<Digital system>
(1) Recording format
: a FLAC or WAV file of 96 kHz / 24 bits or higher is possible
(2) I / F input / output
: 96 kHz / 24 bits or higher is possible.
(3) File reproduction
: The FLAC / WAV file of 96 kHz / 24 bits must be compatible.
(Self-training and rewritten can only be done with FLAC or WAV.)
(4) Processing of
Signal: 96 kHz / 24-bit or higher signal processing performance is possible.
(5) Digital to analog conversion
: 96 kHz / 24 bits or higher is possible.
3 Surely the auditory evaluation is carried out in the production or responsibility of sales.
(1) The auditory evaluation is carried out based on the evaluation criteria of each company, and the final judgment is that the product is suitable for “high resolution”.
