Hi,
While stresstesting a sequencer, at some point audible gaps in the
audio output start appearing. However, when I look at the top output,
it sais the processors are idling about 47% . Activity monitor sais
the sequencer uses 80-88% of the cpus. The PowerMac has 2 2GHz
processors and plenty of free memory.
I wondered if 2 audiographs may help loadbalance the machine, but I
got similar response.
Is it normal that the processors can idle while the audiograph(s)
experience buffer underruns? Or is it the AltiVec units which are
loaded while the rest of the processor is idle?
Can I measure any of this? And are there callbacks in an AUGraph
which are called when buffer underruns are detected?
Thanks for your reply,
