A blend of ‘Environment’ and ‘Tune,’ EnviroTune is an intelligent sound-tuning technology that analyzes listening surroundings in real time to restore musical details easily lost to ambient noise.
The built-in microphone detects changes in ambient noise in real time, analyzing input sound by frequency band to automatically compensate for frequencies masked by noise.
Without unnecessarily raising the volume, the sound continuously adapts to your environment—allowing complete immersion in the original detail of your music, anywhere, anytime.
*What is Group Delay?
It refers to the time difference required for various frequencies to pass through an audio system, causing sound signals across different frequencies to arrive at slightly different times rather than simultaneously.
To deliver the ultimate DAP experience like never before, we incorporated the latest DACs and upgraded specifications, while further advancing TERATON ALPHA—Astell&Kern’s Ultimate Sound Solution.
Perfected through relentless research, TERATON ALPHA is Astell&Kern’s proprietary audio technology designed to deliver sound closest to the original source through effective power noise removal, efficient power consumption, unwavering amplification, and a seamlessly converted audio output interface.
Vivid Original Sound: Digital Audio Remaster Technology
The PD5 features Digital Audio Remaster (DAR) technology, developed to deliver the refined sound of higher sample rates.
DAR upsamples the sample rate of played audio tracks to transcend the physical limitations of the original source format. Higher sample rates enable more delicate and precise playback, bringing sound closer to true analog expression.
It vividly reproduces original recordings, allowing you to experience subtle musical nuances and rich sound at an elevated level.
