How would I find out if an application installed the wavtap.kext as part of its package? I'm experiencing many audiocore errors and am trying to narrow down the cause. 

A Google search has revealed that WavTap could potentially be the cause of these errors. 

WavTap is listed in my Audio Midi Setup despite my not having that application installed. 

I would like to know if it was installed by some other audio application I have as a tool that this secondary application relies upon to function completely/properly or whether I simply installed WavTap, myself, at some point in the past and missed the .kext when uninstalling. So, how might I go about finding out whether or not another application I have installed has a dependency upon WavTap.kext? 

thanks
So, it turns out that WavTap.kext was installed as a part of the Spotydl package, an application that I had uninstalled nearly immediately and erased most traces of. Removing the WavTap.kext and the Spotydl .plist and .bom appears to have resolved some of the coreaudio errors, though, a reboot will be required to see if the component errors are still present and it seems unlikely that this issue was the cause of those. 

If anyone is aware of a simple uninstaller which parses the InstallHistory.plist, please, let me know about it. Thanks
