Winamp 的 DFX plug-in

之前好像有人介紹？ 做 DSP FX 效果器的那間公司出的。

DFX (TM) is designed to dramatically enhance the listening experience for users of Internet audio formats such as MP3, and Microsoft's Windows Media streaming format.

DFX is the first plug-in to make truly professional quality audio processing available to Internet audio users. DFX was developed by Power Technology, a company with vast experience in DSP based audio processing. Power Technology's professional audio products have won multiple awards from leading professional audio publications, and this high level of audio algorithm expertise was used to create the patent pending DFX plug-in.

DFX enhances Internet oriented audio listening experiences by correcting for the sonic limitations of all the popular data compressed Internet audio formats. Data compressed audio suffers from two major problems: loss of high frequency fidelity and loss of stereo separation and depth.

DFX compensates for the loss of high frequency fidelity by carefully regenerating the missing high frequency harmonics in the audio. DFX then compensates for the reduced stereo imaging and depth by carefully generating ambience and stereo depth.

An additional factor limiting the quality of Internet audio playback is the use of speakers that are narrowly spaced and located close to the listener's ears. These location constraints reduce the perceived stereo field and reduces the natural room ambience which is important to good sounding audio. In addition to compensating for reduced stereo depth in the audio source, DFX's added ambience and imaging works particularly well in correcting for these limitations of closely spaced and located speakers.

Typical PC based multimedia playback systems and even home stereo playback systems also suffer from limited dynamic range and headroom. DFX compensates for this limited headroom by carefully processing the audio to increase the perceived loudness of the audio without altering the perceived dynamic range. This can dramatically increase the undistorted playback level available when listening to MP3 and and other streaming audio files.

DFX performs all audio processing with 32 bit floating point precision, yielding truly professional audio quality. Since Internet audio playback systems currently only support 16 bit audio playback, as a final processing step DFX carefully re-dithers the audio signal to the final 16 bit resolution using Power Technology's proprietary high quality dithering technology. Re-dithering allows a dynamic range in the playback signal that actually exceeds the theoretical limit of a 16 bit playback system.

有 for Winamp，Sonique，RealNetworks 三種版本可以下載 http://mail2.scu.edu.tw/~u6506240/dfx_winamp.zip http://mail2.scu.edu.tw/~u6506240/dfx_sonique.zip http://mail2.scu.edu.tw/~u6506240/dfx_real.zip

蠻不錯的，不能在cake或是sf45中使用嗎？

其實還是補得有些過份，和原來的音色已經不一樣了，不過他的預設值真的設得蠻好的，聽起來還不錯... 不能在 sf or cake 底下用耶，不過可以改用同一間公司出的 DirectX 效果器，DSP FX，記得我跟您提過的某個 plug-in 的網站嗎 <img src="http://www.dearhoney.idv.tw/UBB/NonCGI/icons/smile.gif" width=15 height=15> DSP FX 的種類更多，參數的可調性更大，但是我用 DSP FX 都調不出和 DFX 一樣的效果，果然功力就是有差 T_T
