CDex 是個免費的軟體,它主要的功能是可以將音樂 CD 中的音軌轉錄成 WAV 或者 MP3 格式的檔案。
或許你會認為你只要用音效卡就可以將音樂 CD 裡面的音軌轉出來了,為什麼還要用 CDex 呢?因為用音效卡轉錄 CD 有個缺點:在轉錄的過程中,CD 中的訊號會先從 CD 轉成「類比訊號」,然後才被音效卡轉為「數位訊號」。在這個音訊轉換的過程中難免會造成聲音品質的流失!而 CDex 則是直接從 CD 上讀取訊號,然後轉成 WAV 或者 MP3 格式。
What's CDex?
CDex can extract the data directly (digital) from an Audio CD, which is generally called a CD Ripper or a CDDA utility. The resulting audio file can be a plain WAV file (useful for making compilation audio CDs) or the ripped audio data can be compressed using an audio encoder. Many encoders are supported, to name a few:
* Lame MP3 encoder
* Internal MP2 encoder
* APE lossles audio format
* Ogg Vorbis encoder
* The Windows MP3 encoder (Fraunhofer MP3 encoder)
* NTT VQF encoder
* FAAC encoder
* Windows WMA8 encoder
In addition, WAV files on the hard drive can be converted to a Compressed Audio File (and visa versa). CDex also supports many audio file tag formats like the ID3V1 and ID3V2 tags, which can be automatically inserted as part of the ripping process.
