Question

我一直在macOS上使用AudioKit 4.7.1 AKPeriodicFunction，即使对于简单的用例，也注意到内存在增加。我尚未在iOS上进行测试。

我实现了一个简单的示例，您可以通过泄漏来跟踪内存。

        let path = Bundle.main.resourcePath! + "/leadloop.wav"
        let player = AKPlayer(url: URL(fileURLWithPath: path))!
        player.isLooping = true
        let periodicFunction = AKPeriodicFunction(frequency: 5.0){
        }
        AudioKit.output = player
        try? AudioKit.start(withPeriodicFunctions:periodicFunction)
        periodicFunction.start()
        player.play()

在此示例中，内存不应增加。这是堆栈跟踪中最重的部分，可能会有所帮助，
