Audio stuttering

[wibem]

I´m using M7 on a Mac mini with OSX 10. 6.8, CoreDuo 2.26GHz and the inbuild audio-output. When I playback the demofile Airtime the audio-playback is stuttering at the end of the song. The demofile uses only inbuild synths and has only a few instruments and effects. There should be no problems, but there are. The CPU-meter of M7 is turning red, but the taskmanger indicates cpu-usage is less than 50%.

That demo project is indeed using quite CPU intensive sounds. You could try Audio Setup -> Num Audio Processor Threads = 2.

These are different values. See http://www.mutools.com/info/docs/mulab/transport.html
