Hello,
I recently finished an auhal output plugin for the libao library
(http://www.xiph.org/ao).
During my testing I noticed that I only need some higher load on my
powerbook (bouncing dock icon + compile) to get buffer underuns
(stuttering). First I thought that I did something wrong and so I
tried SDL which also has support for CoreAudio, but I got buffer
underruns there too quite easy.
I know that I could increase the ringbuffer size but this also
increases latency. Since I never get dropouts in quicktime or iTunes
I wonder how they do that.
Kind regards,
Michael
