ios - InstallTapOnBus - 用于输出信号
<p><p>在主题中,我想分析输出信号的缓冲区。我已将此功能( InstallTapOnBus )用于麦克风信号,但不适用于输出。有人知道怎么做吗?</p>
<pre><code> let bus = 0
let node = engine.outputNode
node.installTap(onBus: bus, bufferSize: AVAudioFrameCount(BUFFER_SIZE), format: node.outputFormat(forBus: bus), block: { (buffer : AVAudioPCMBuffer ,time : AVAudioTime) in
...
})
try! engine.start()
}
</code></pre>
<p>它给我一个错误:“所需条件为假:_isInput”</p></p>

<p><p>您是否尝试过直接点击混音器而不是麦克风?</p>
