建議採用premiere6.5或sonic公司出有關聲音處理產品,應該有不錯的效果, (但請注意, 所有這類的軟件並不建議將volumn過份提升, 否則會弄致出現嚴重雜音,及變質, 因此仍建議改善擷取時的質素.


另外, 有部份網頁不建議採用tmpgenc單獨處理聲音檔......

摘自tmpgenc setting網頁
There are two reasons not to encode the audio in TMPGEnc:

The first is the fact that MPEG audio is not standard on all DVD players. Although it is supported by all PAL players (and many recent NTSC models), some authoring programs still refuse to add MPEG audio directly to their projects, and will instead convert it to PCM (uncompressed). Since MPEG audio uses lossy compression, the quality that was lost in the compression is not recovered. By contrast, the space that was saved by the compression is lost again. So, using MPEG audio in these programs is a lose-lose situation. The only two formats guaranteed to be compatible with all players are PCM and AC3.



The second reason is the fact that there are several MPEG audio encoders that produce better quality than TMPGEnc. So even if your authoring program does support MPEG audio, and if you're sure the resulting discs will only be played on DVD players that support MPEG audio, you should still use TMPGenc only for the video, and encode the audio in a separate application (if you do a quick search on the web for "MPEG audio encoding" you should be able to find several guides about the subject).
