[情報] iOS 12.2 beta 提升語音訊息品質
Apple Improves Audio Messages Quality in iOS 12.2
In the iOS 12.2 beta,
Apple has improved the quality of the audio messages
sent in the Messages app after switching to a new
Opus codec at 24000 Hz,
up from the previously used AMR codec at 8000 Hz.
Apple previously used the .AMR file format
for its audio messages,
but in the beta, has swapped over to .CAF.

能注意到這個改變真是太厲害
應該是因為美國人常用 iMessage
隨著網路即將進入 5G 時代
加強語音品質也是理所當然
