Tuner Nerd testing audio delay

I've just received my Knock Monitor pro kit (v3 so single box) and have just had a mess on testing it on the bench. I've noticed that there is a significant delay (over a second) between the sensor registering (me tapping it) and it actually registering on the software. Am I missing something here? I realise this won't cause a problem replaying the file back but it kind of makes the system useless as a live monitoring system

Hello i have heard similar things possibly from the Bluetooth audio latency

but have not tested it my self to be able to confirm this

Regards Ross

Thanks for the reply Ross. I never bothered with the bluetooth headphones as my plan was to plug a set of wired headphones to my laptop but even coming through the headphones you can hear a significant delay
