iOS版 - 从后台程序访问输出音频 [英] iOS - Access output audio from background program

问题描述

情景：我的应用程序在后台运行。一个iPhone / iPad的用户推出的iPod应用程序（或潘多拉或播放音频的另一个程序）的设备上，开始播放音乐。我的应用程序检测到音乐现在玩和记录或以某种方式做的事情与当前播放的音频（如流式传输到一台服务器），所有的同时仍然在后台运行。

Scenario: My app is running in the background. An iPhone/iPad user launches the iPod app (or Pandora or another program that plays audio) on their device and starts playing music. My app detects that that music is now playing, and records or in some way does things with the current playing audio (like stream it to a server), all while still running in the background.

这可能吗？任何人都可以点我在正确的方向在SDK中如何做到这一点？

Is this possible? Can anyone point me in the right direction in the SDK on how to do this?
