生成的触觉数据连同音频数据一起发送到音频 HAL,这将要求设备支持音频耦合-触觉播放。 在这种情况下,仅在支持音频耦合-触觉播放的设备上创建效果。 调用 HapticGenerator#isAvailable() 以检查设备是否支持此效果。 应用程序可以创建 HapticGenerator 对象,以在音频框架中启动和控制此音频效果。

音频硬件抽象层(Audio HAL),它为硬件提供了一个独立于设备、独立于驱动程序的接口 Core MIDI ,它提供了用于处理 MIDI 流和设备的软件抽象 Host Time Services ,提供对计算机时钟的访问 当需要尽可能高的实时性能时,可以编写 Mac 应用程序以直接使用这些技术。 然而,许多音频应用程序并不访问这一层。 事实上,iOS ...

不能从AudioServerPlugin控制kAudioDevicePropertyBufferFrameSize属性。它仅供客户端进程用来设置其IO进程接收的IO缓冲区的大小。 当多个客户端同时使用您的设备时,CoreAudio允许它们都使用不同的IO缓冲区大小(可能不是彼此的倍数/因子),因此您的插件必须处理各种大小的缓冲区。 来源:https://lists.apple.com/archives/...
