Thats important. I think my version keeps it live by default. You need to check this. If the stream is not kept live, you won't get a time lock.

Hello again,

I double check, and still have same problems. I got about 1m shift in about 30s, making it useless to compare relative phase between driver.

I shall receive soon a better soundcard, I will test again with it and let you know if I got better result.

So,

I receive my new sound card (m-audio fasttrack) and the problem disappear....

on windows 7 I had to use ASIO driver to use it efficiently (I don't understand anything on the way windows 7 work with sound card....). On XP, no need of specific driver

Look like most a build in sound card and cheap USB soundcard have a phase problem between input / output

Thanks for your inputs

I have the same problem when using ministreamer with minidigi and minidsp. With my Maudio soundcard, there is no such problem. Do you think it is the USB (ministreamer) soundcard issue?
anyone have an idea how to fix it?

Example , the red is a loop-back real-time measurement and the blue is the same measurement but first saved and then loaded.

Hmm that is interesting. I'll have to try that out myself. How about when you have saved the complete measurements as a zip file?

Tony.
