Have you tried enabling 'Synchronize to output sound card' (something like that) in the input sound card settings of Stereo Tool? If not, I don't have much experience with VAC, but others do... So they might have something more useful to say. |

More info needed, like.. what vac version, system cpu, OS, configuration .. etc.. |

I will guess that you are not planing to use ST for FM.. but for streaming ... Open VAC panel and: - Fix VAC sample rate (SR) to 44100 - 44100 Hz - Fix VAC bit depth (BPS) 16 - 16 bit - NC 1..2 - All cables "Stream fmt limit" to "cable range" - Turn off, channel mixing, PortCls and watermark - Max Inst 20 - MS per int 1 - Worker threads 2 or 4 (depend on multi and hyper threading of your CPU) - Prio 31 Also.. - Check CPU usage if U/O flows still occures - Make sure that 'realtime' is ON is ST |

excuse my late reply, I have attached a picture http://www.radiohlr.dk/wp/wp-content/up ... 04/vac.png. I still have the problem. My CPU load is 62% |

Thanks for mentioning this! I would notice that sound would slowly vary over time with high freq's decreasing and weird phasing. I thought it was due to memory leaks of Edcast encoder. I'd reboot it and sound would improve.After putting a check mark in "synchronize to sound card", sounds stays constant with no strange variations over time on my VAC implementation. Thanks so much! |

I recently upgraded to the latest VAC. If "Ms per int" is set to 1, I get too much stuttering and clicking. I have to set it to 10 or 15 for non-skipping sound. With Stereotool, what does CPU usage "Realtime" mean, as compared to the other two settings? |

"Realtime" is the Windows (task manager) priority "Realtime". It's not really realtime though because Windows isn't a realtime os. |
