I'm working with 96 kHz files, but my built-in audio device does not support high sample rates. Therefore Spark resamples the output to 44.1 kHz. As soon as I insert a PowerCore plug-in, I get a very high CPU load, and a audio engine error message.
What can I do about this?
When Spark performs resampling, the audio data is processed in a different way. Set the ADMA buffers in your PowerCore control panel to 2 or higher. This will reduce the host CPU load to normal levels.
