Using the Astell&Kern
1. What is MQS?
oMQS stands for “Mastering Quality Sound” and refers to sound or music
files saved in a lossless format, straight from the studio-mastering source.
Because less data is lost during the digital mastering process and the
sound quality is distortion-free, a dramatic difference from the 24bit
source data contained in MQS files and CD (WAV)/MP3s can be heard
and felt.
oMQS files are often in 24bit WAV or FLAC formats. With the encoding
process in the AK100 MQS Portable System, MQS music and sounds are
more refined and pure.
MQS –24bit, 96 –192kHz
CD –16bit, 44.1kHz
MP3 –16bit, 128Kbps –320Kbps, 44.1Khz
