Apple Lossless 音樂無損格式宣布開源
由 Apple 所創造的 Apple Lossless 音樂無損格式(ALAC)宣佈開源
ALAC 並不真的無損,但在盡可能壓縮音樂檔案大小後,仍舊可以保持超高質量的聽覺享
受。
其轉碼後的檔案大小,大約為原始檔案的 40% ~ 60%,如此高的壓縮率還可以接近無損真
的很厲害!
不過檔案大小還是遠大於 MP3 格式,且僅有 Apple 一家的設備可以使用,所以幾乎沒有
流通性與商業價值。(Gary 個人倒是把 Apple Lossless 當成由 CD 輸入音樂的第一選
擇)
如今 Apple 宣布將此編碼開源,也許會有新的風貌也說不一定。
詳細的資訊可以參考:
