最近迷上玩串流的AirPlay串流音樂所以買了的AirPortExpress,因為有光纤输出,打算接DAC,購買前還打電話跟客服確認是否能達到24bit192,回答说可以,便下手購買了,结果回家一是只能支援到16bit44.1,尬,被骗,音質还比IPHONE还差,網速也普普,使用itunes家庭共享,24bit音樂也不是太稳定,不知到能不能換購AirPort Time Capsule - 2TB的機種嗎雖然沒有光纖,但網速更快,因該能更穩定吧
from Wiki The AirTunes part of the AirPlay protocol stack uses UDP for streaming audio and is based on the RTSP network control protocol.[12] The streams are transcoded using the Apple Lossless codec with 44100 Hz and 2 channels encrypted with AES, requiring the receiver to have access to the appropriate private key to decrypt the streams.[13] The stream is buffered for approximately 2 seconds before playback begins, resulting in a small delay before audio is output after starting an AirPlay stream.
