網上有高人推薦Foobar2000 用 Kernel Streaming 來 bypass Windows Kernel ...
為了進一步遏抑Tannoy Autograpgh Mini 高頻偶爾尖聲，在兩個喇叭之間牆上加上了一塊 egg crate 海綿。
好像是有發揮作用。
意外收獲鋼琴聲是比以前響亮。
加上以前放在牆角那一塊，總共是放了兩塊海綿。
理論上收音物料是會遏抑高、中頻，但不會減少低頻。 https://www.crutchfield.com/learn/room-acoustics-home-audio.html
"The sound-absorbing effectiveness of some common room surfaces
Fibrous materials like carpet and drapes provide significant absorption above 500 Hz but have little effect on lower frequencies. Conversely, window glass and drywall can absorb bass frequencies but are very reflective above 500 Hz. The most successful approaches combine materials like these with room treatment products.
Try to balance the amount and frequency of the absorption in your room to achieve some bass and high-frequency absorption. Typically, bass absorption is more difficult to achieve."
現時是用 Asus Tinkerboard S 接Audio-GD NFB15 DAC 作為音源，聲音尚可一聽。
