radhk兄
主要要一隻有line out嘅sound meter, 一部PC/notebook 有line in(唔係mic in), 如果無line in就要買一隻有line in嘅外置sound card(約四五百)
詳細方法可以參考下O的大佬之嘅嘅post

好鬼想玩room eq............不過部net book又無line-in.............今晚裝左個software睇下部netbook 1024x600既screen出唔出得哂個software先............
跟住再要買外置sound card...........
請問要拉平條curve係唔係用"減" 好過"加"
之前睇過O的書話加嘅失真比減嘅多{:1_347:}

的確減好過加﹐一切都係S/N ratio問題
