Re: USB Mic Acoustic Timing

Hi John thanks

So select Acoustic Timing Reference in the preferences and leave selected for all measurements for now on?

Is there anything else I should select/change in the preferences?

Thanks again

Select it when you need an acoustic timing reference for a measurement

Re: USB Mic Acoustic Timing

That really depends on what it is you are trying to do. If you want measurements that showing timing relative to a reference, turn it on. If you don't, turn it off.

Re: USB Mic Acoustic Timing

Hi John thank you.

Here is a step by step from Minidsp
Is this for HDMI?
https://www.minidsp.com/applications...ing-time-delay

In the preference soundcard panel I have set the following is this correct?
I have not got HDMI and are using Java

Output Device = O/S soundcard (not sure what it is called
Output = Default
Channel = Right

Input Device = UMIK
Input = Default
Channel = Left


Thanks again

Re: USB Mic Acoustic Timing

As a general point, do not leave the input and output on default, set them to the option offered in the drop-down menu.

What are you trying to achieve by making measurements with a timing reference? If you can explain what you are trying to do it will be easier to understand whether the acoustic timing reference will help and, if so, how you should use it.

Thanks John

I am trying to set the distance in the receiver for time alignment.

Thanks again

Re: USB Mic Acoustic Timing

Alignment of which speakers? If it is the main speakers and/or surrounds, use a tape measure. If it is the sub then the acoustic timing reference will not be helpful as it cannot accurately determine delays for subwoofers. There are other threads on setting sub delays, such as this one.
