Hi all.
I am currently testing a plugin that I wrote which reads sample data
from disk and mixes it with the incoming audio data.
Everything works fine when I simply play some audio file in Garageband
or Logic and insert my plugin to that channel. The resulting output is
channel audio mixed with audio from plugin.
However, when I enable software monitoring on that track the samples
from the plugin are playing too fast.
The problem seems to be that the process() methods of the plugin are
called more often per second when I enable software monitoring.
How is software monitoring handled in Audio Units? How can I tell
between audio from the track and audio from input monitoring from
within the plugin?
I used the AUEffectBase / XCode Template to create the plugin and do
most AudioUnit specific stuff in the Kernels.
Can anyone help?
Thank you,
Normen Hansen
