题目不知起什么好,就是想记录一下最近了解的Audio相关的。

Tables | Language | base | API level | Example |
---|---|---|---|---|
AudioTrack | java | office API | 3 | - |
AudioTrack | C++ | office API | 3 | - |
OpenSL ES | C++ | - | 9(2.3) | android-ndk/audio-echo |
android.hardware.audio.low_latency | - | office API | 9(2.3) | - |
low_latency | - | office API | 16(4.1) | - |
USB Audio | - | - | 21(5.0) | - |
android.hardware.audio.pro | - | office API | 23(6.0.1) | - |
AAudio | C | - | 26(8.0) | android-audio-high-performance |
注:
android.hardware.audio.low_latency
并不一定要放到android.hardware.audio.low_latency.xml
中,比如坚果P2就把其放到了/etc/permissions/mtv_core_hardware.xml
中。且这个标识是主动型标识,不需要任何实现就可以标上该设备支持low_latency
也就是45ms延迟。大多设备都标注上了,但是其实并没有达到这个延迟时间。
