As the transmission quickly takes over the world of audio, the sound quality has made a massive immersion.
The so-called “lossless” audio still includes compression and digitization that compromises the sound captured by the original master. Direct tape recordings in the 1950s far outweigh Drake’s latest album in terms of pure sound quality.
A new audio chip created by Japanese sound company Velvet Sound, a division of Asahi Kasei Microdevices, aims to give what it calls the experience “as if you were there”.
The chip plays “up to 10 trillion times” as much sound data as a compact disc.
CDs are 44.1 kHz and 16-bit, with a sampling rate of 44,100 times per second.
High-resolution digital audio has 96 kHz and 64 bits (sampling rate 96,000 times per second).
Asahi Kasei Microdevices chips reach 1,536 kHz and 64 bits, according to the company.
As Nikkei Asia explains, “In terms of sound data, that means a theoretical upper limit of about 9.8 trillion times that of CDs.” This, of course, is still theoretical.
“High-speed digital signals of ones and zeros do not exist in nature, so these signals are the source of noise,” said Jun Tokunaga, head of audio product planning and development at Asahi Kasei. Microdevices.
At the moment, this is exclusively for audiophiles and is unlikely to reach the mass market.
With this volume of data, 7 gigabytes are needed for a single five-minute song, which means that transmission is impossible with the current speed of the Internet.
