剛換win2000 沒多久,對win2000還不太熟,
只覺得用win2000配vibra128配5880wdm27525版
ds ssrc2.2.3聽起來不錯^^
今天試著去逛win2000 的各種系統設定..
結果看見....
win2000下的音訊播放設定 裡面的[硬體加速] 跟 [取樣頻率轉換品質]
預設值居然是 標準加速(四段的第三段) 跟標準取樣(三段的最差那項)
哇咧 …當然是馬上都調最佳
下一首歌放出來之後 非常明顯感覺到 音質整個不一樣了 :eek:
整個明亮開闊起來∼ :o :o :o :o :o :o
被預設值悶了好一陣子………現在感覺很棒!
resample quality 真的差很多∼
可恨的預設值 不知道是win2k 預設值 還是我的音效卡driver的預設值 >!<
上來報告一下 不知道98/xp 預設值是不是也是這樣? 沒調過的就調調看吧

win2000 選項在
控制台→聲音多媒體→音訊sheet→播放的[進階]選項→效能sheet 就有了[/b]
Win2000 下的硬體加速 / 取樣頻率轉換
版主: DearHoney
The hardware-acceleration slider has four settings that range from "None" (level 0) on the left to "Full" (level three) on the right.
0/Emulation: Forces emulation.
1/Basic: Disables hardware acceleration of DirectSound secondary buffers.
2/Standard: Enables hardware acceleration of DirectSound secondary buffers but disables vendor-specific property-set extensions. (On Windows 2000, the Standard setting is selected by default and can be changed only by direct end-user action. This purpose of this behavior is to improve stability and to prevent software from placing the audio system in a state from which it cannot be removed without rebooting.)
3/Full: Enables hardware acceleration of DirectSound secondary buffers and enables vendor-specific property-set extensions. (This is the default setting on Windows 98/Me and Windows XP. Again, for the sake of stability, the default setting can be changed only by direct end-user action.)
Check WinDDK for detail

透過SSRC轉成48KHz後,(假設音效卡是Audigy)
還會被音效卡driver or KMixer再作一次笨笨的 48KHz -> 48KHz轉換嘛?

Audigy不確定, 但我覺得一樣笨的機率比較高...

SB Live!的 44.1 -> 48 KHz果然慘不忍賭!kouyoumin 寫:SBLive ValueGPF 寫:請教一個問題..

不知道這是不是造成SB Live!的CD-ROM SPDIF in
音質會如此差勁的原因??
