佢講到個後級咁食電又要粗線又剩，但就插足六件，我真係幫佢唔到

hdmi線我就唔太清楚佢咩原理
但係干擾都不外乎係磁場同埋線長
因為所以digital都有set 一個固定既電壓值先至會開始讀取
例如電腦發出黎係2.3v, 收果個可能唔可以少過2.1v,如果唔係就直接當冇收過野出error
只要干擾咁岩令到佢電壓既variation係2.09-2.11咁跳就會導致訊號不穩
如果個標準越高, for example 普通hdmi 1080p可能容許係2.1, 4k既話可能只可以容許2.28v以上, 咁樣對線材既要求就會越高
都係果句我唔係video人,我係以audio既傳輸原理去估計hdmi既運作
唔一定岩煩請指教

我就試過做demo 有d唔係audio人哄埋隻mute左既喇叭聽底噪然後話咁大底既得唔得架
在場既師兄都指住黎笑
line array吊咁撚高鬼聽到依d noise咩
淨係你部冷氣機都嘈過佢啦

ACK係行Bulk mode先有 
Real time野, 例如audio, 係行Isochronous mode
https://source.android.com/devices/audio/usb#isochronous
Isochronous transfer mode
USB audio uses isochronous transfer mode for its real-time characteristics, at the expense of error recovery. In isochronous mode, bandwidth is guaranteed, and data transmission errors are detected using a cyclic redundancy check (CRC). But there is no packet acknowledgement or re-transmission in the event of error.

不過有d 老屎忽係真係勁既
經佢tune完套野係真係好好多
後生果輩依家好多都係用mic cap套curve黎拉條eq
佢地果班就直接聽到邊個frequecy黎執幾多q幾多gain

data package lose左又無buffer直頭係無左聲, 最簡單就係藍牙耳機, 因為無ram做buffer先成日會段線, 無data到唔係會走音, 加下係digital年代, 聲音data數碼化一係就有聲, 一係就無聲, 玄學撚無聲聽出黎會走音？
cd player都係即時轉code, 花左讀唔到係讀唔到data, 音響撚係會聽到走音而唔係lag左
佢部amp仲勁過google個ai, data lose左個cpu都照轉到code出聲
如果寫code就正, 個program run唔到同佬細講因為條usb線lose左data先會有bug, 個佬細即時唔係炒你而係即刻搵人整條咩晶銅既usb線同lan線出黎

Bose apple耳機好？
清你玩鳩我？
真係想討論既，麻煩清你去轉旺角星際，叫店員比部m2 + ie800s你聽symphony/ live performance，你都覺得70蚊耳機贏既我冇野好講
利申：玩同聽classical music，同樣覺得高級音響撚好多玄學
