I use a Motu fireware UltraliteMK3 for the sound interface and:
VMIX software is set to 48khz
Motu interface is set to 48khz ( as I can read and see on the device and in the control panel )
but I get "44100 Hz 32 Bit Float 2 Channels" set in the input audio format????

And the sound is pitched down !!!???

So how can I can set this ?

I don't own a Motu but for now, you could always change the VMix Master sample rate to 44100: https://www.vmix.com/hel...tm?AdvancedSettings.html

@ Vince: it was not working....

IN fact I got this answer from VMix

"Hi Ronan,

By default, vMix is set to 48000Hz @ 32Bit Floating point and masters at 16Bit PCM:
Audio Formats in vMix | vMix

I am not familiar with the MOTU UltraLite Mk3 device, but it should have similar options to the SHURE MVi as mentioned in this article:
Shure MVi low pitch / audio speed up issue | vMix
As such, you will need to make changes within the device's own settings as it is not possible to select or choose this from within vMix.

I hope that helps.

Kind Regards,

Greg Akeson


Thanks to Greg, that's the point and as I come from the Apple Word, I'm not used with Windows "multiple" control panel....
The problem is not in the MOTU control panel but in the WIndows Sound advanced settings. And I have a french version of Win10 so the translation of the tabs in the sound panel are "weird" : the setting of the default sampling audio rate is called " Statistiques avancées" "Advanced Statistics" ??? ( thanks to google, reverso ...)

Hope this help!
