I am having a weird problem initializing AudioKit AKWaveTable node. I am trying to change the sample rate of a sound on the fly and I thought AKWaveTable would be the best option to do this. According to the documentation, this initialization function already sets default parameters for most of the parameters, so I would only need to give it a filename:

self.file=try  AKAudioFile(readFileName: fileName)
self.player=AKWaveTable(file: self.file)

I get the following error upon running app:

2018-10-21 17:22:29.276450+0200 AKSoundPool[1479:44079] [default] Unable to load Info.plist exceptions (eGPUOverrides) 2018-10-21 17:22:29.570701+0200 AKSoundPool[1479:44079] [AudioHAL_Client] AudioHardware.cpp:666:AudioObjectGetPropertyData: AudioObjectGetPropertyData: no object with given ID 0 AKWaveTable.swift:init(file:startPoint:endPoint:rate:volume:maximumSamples:completionHandler:loadCompletionHandler:):218:Parameter Tree Failed 2018-10-21 17:22:29.607702+0200 AKSoundPool[1479:44079] [avae] AVAEInternal.h:70:_AVAE_Check: required condition is false: [AVAudioEngine.mm:393:AttachNode: (node != nil)] 2018-10-21 17:22:29.609506+0200 AKSoundPool[1479:44079] required condition is false: node != nil

I also tried setting all of the other parameters to 0 but I get the same error, parameter tree failed.

Any hints? Am I on the wrong track?

Thank you

Try disabling App Sandbox in your project configuration. In XCode it's under "capabilities". I had the same issue and my app was in a sandbox where some key features needed for AudioKit were disabled.

  • what sense would this make if I want my app on the app store? Does iOS have the same problem? Havent tried on iOS yet.. Can someone working in AudioKit confirm this? – Oriol Gómez Oct 24 '18 at 18:30
