Let’s compare the high resolution and sound quality of a CD<\/p>\n

<\/p>\n
This is a video of the famous Star Wars background music, played alternately in high resolution sound quality and CD sound quality, and distributed left and right. Watching with large speakers and headphones is recommended.<\/p>\n
Without watching the video of this video, it is now high resolution! CD sound quality now! I wonder how many people can know.<\/p>\n
To be honest, I couldn’t tell the difference. Hmmm, does high resolution sound smoother in the high range? I just felt that. Is it because the headphones are around 5,000 yen?<\/p>\n
It was a result that I couldn’t get enough of, so I found an interesting video when I was researching various videos.<\/p>\n
This video whose sound quality increases with the passage of time.<\/p>\n
kbps is the so-called “bit rate”, which is the product of the number of bits (bit) and the sampling frequency (kHz) explained above.<\/p>\n
In this video, the bit rate gradually increases from 32 kbps to 160 kbps as you go. At first the sound quality is like a radio, but at the end the sound quality is clear and I am impressed. It seems that the sound quality is MP3 at 128 kbps. With this, I can see the difference in sound.<\/p>\n
By the way, the sound source of the CD is
\n44.1 kHz \/ 16 bit = 1.411 kbps and the high resolution sound source is 96 kHz \/ 24 bit = 4.608 kbps.<\/p>\n
So you can see how loud the audio is, by the way, when you listen to it in Hi-Res audio, it looks like this.<\/p>\n
Is there a difference between the sound quality of a CD and high resolution?
\nSome people may tell the difference, but honestly, I can’t tell the difference between high resolution and CD sound quality.<\/p>\n
Somehow even if the sound quality gets louder than this it is indistinguishable to my ears. I thought, so I looked it up.<\/p>\n
It’s quite a manic and professional story, so if you chew it roughly<\/p>\n
When listening to this video, how high frequency could you hear?<\/p>\n
I think it is around 16000Khz, the high resolution also covers high frequencies above 20000kHz at the end of the video.<\/p>\n
“The high resolution covers the range that I can’t hear, so I can’t really tell the difference.”<\/p>\n
The result was that.<\/p>\n
So hi-res sound quality doesn’t mean a thing? Deny the high resolution! It’s not that people who understand it can tell the difference, and some people can tell the difference if it’s their favorite song.<\/p>\n
Like a live orchestra, you can enjoy not only your ears but also the vibration of the air, so it may be different if you listen at a high volume.<\/p>\n
Each person has their own sense of it and each person has their own tastes of it.<\/p>\n
It is best to listen at the bitrate \/ environment where you feel the best sound.<\/p>\n","protected":false},"excerpt":{"rendered":"
