Convert a vinyl record to HiRes
In modern terms, it is a digital archive of analog records. .. (bitter smile)
If you burn an analog disc with the same settings but different sample rates and bit depths, you can achieve “almost the same sound source”, “same device settings” and “different formats”, so I tried it.
I mean, half the reason I bought a used FA-66 was “record dubbing,” so I experienced that a long time ago. (Hahaha)
From this moment on, we are in the world of
“individual opinions”
“there are individual differences in how we feel the effects” and
“compared to our company”
.
(Since we haven’t confirmed the similarity between various devices, please speak half-heartedly.)
I certainly felt the difference in sound when I changed the sample rate, but I felt the difference when I changed the bit depth was greater than that.
In words, raising the sample rate made it feel smooth and courteous, and lowering it made it sound punchier and thicker.
The 24-bit bit depth is more realistic and I felt the sense of location and space became clearer.
By the way, when dubbing analog records, I feel like I prefer 48kHz/24bit to the higher spec of 192kHz/24bit.
So today, in analog record archiving (for playback purposes on NW players, etc.), the recording is done at 48kHz/24bit, and the level is not altered and is saved only by adjusting the read in/out.
In order to be put on a CD, it is recorded at 44.1 kHz/24 bits, and after adjusting the level, etc., it is converted to 16 bits.
In any case, the flavor is different from the “Oh! Weird” feeling you get when you switch from the CD version of the same song on sale to the hi-res version, and the difference is very small.
The
44.1 kHz/16-bit PCM has a signal frequency of up to 22 kHz and a dynamic range of 96 dB.
96kHz/24bit PCM has a signal frequency of 48kHz and a dynamic range of 144dB.
On the other hand, human hearing varies greatly from person to person, but the frequency is said to be up to about 20 kHz (for young people only) and the dynamic range is up to about 120 dB (20-bit equivalent) (superhuman level ) .
If you just think it has performance at first glance, it is normal for people not to feel the difference whether it is hi-res or CD in the direction of frequency characteristics, but since the dynamic range has the ability to exceed 16 bits , is is 16 bit You can feel the difference between 24 bit.
Note 1
It seems that there are times when you dare to limit yourself to the conversion without manipulating the sound.
There are also little “habits” that depend on the format conversion tool (converter, encoder), so I heard from the engineers that it is quite difficult to select only that.
