Android 5.0 支持USB DAC 96/24b sampling

睇黎又會有新玩意, 唔知邊d usb dac 會compatible

其實4.1開始已經玩緊
不過唔係所有app support 24/96 output
我自己Sony Z1f + usb audio pro , 自用Apex Glacier
試過Sony PHA-2/3, JVC ax7, Fiio E18 都出到聲
煩在要自制micro<->micro usb 線

而家有offical API 支持,d app update 下又有Hi Res玩,我都有玩usb audio pro 加E17,不過界面唔多好用,買咗玩了—輪就放低,而且話唔定可以好似apple 機,headset 加dac 用lightning出,比android 機用usb port出headset.
好可能會多番人買portable amp+dac,呢輪好似portable player玩的人多了

最後都係冇 24/96 support

Android support for USB audio class
________________________________________
Host mode
Android 5.0 (API level 21) and above supports a subset of USB audio class 1 (UAC1) features:
•        The Android device must act as host
•        The audio format must be PCM (interface type I)
•        The bit depth must be 16-bits, 24-bits, or 32-bits where 24 bits of useful audio data are left-justified within the most significant bits of the 32-bit word
•        The sample rate must be either 48, 44.1, 32, 24, 22.05, 16, 12, 11.025, or 8 kHz
•        The channel count must be 1 (mono) or 2 (stereo)
Perusal of the Android framework source code may show additional code beyond the minimum needed to support these features. But this code has not been validated, so more advanced features are not yet claimed.
