How to Listen DSD Live Streaming

DSD Live Streaming is a test to demonstrate live streaming of concerts over the Internet.
By using the DSD 5.6 MHz method, you can enjoy concerts with high sound quality.

What is the DSD 5.6 MHz method?
This is a conversion method used when converting analog sound sources to digital. High-resolution distribution is very popular these days and is becoming more common. With DSD 5.6 MHz, an enormous amount of information is recorded by sampling the sound wave at a sampling frequency 128 times that of a CD to enable the transmission of faithful, high-quality reproductions of analog audio.
