_____A NEED TO KNOW___ LATENCY 101___ a short why, how and WTF

HOW LONG IS SHORT

Any time you digitally team with audio, the digital device has to first record
what you input into it, like a vocal or guitar etc. and then convert it back to a signal the speaker can send back to your ears.

This is a two step process. The signal being recorded digitally than that digital recording being converted back as a second step to analog again. 

The process takes time. Although most devices are so fast it is imperceivable a lot of guys say they can hear and 'feel' it. Even more guys will not buy a product unless this spec meets some high end minimum time.

REALITY CHECK

Conversion is measured in milliseconds. 

___ 1ms is 1/1000 of a second
___the worst of current gear takes about 5ms
___if you are 10' away from your guitar amp using 

     a guitar cable it takes 8.8ms for your ears to hear the speaker.

TRY IT

___ so adding a wireless is like standing back 
      back 12' from your amp. 

      Try it ...stand back 10' and play with your cable 

      plugged in then compare it to 12'.

___Either you will tell us all there is F-all difference

     or WTF ...you'll tell us a big fat one! 

       

If recording, such delays, even this short can cause synchronization problems as there may be multiple delays in the system. 

In these cases it is usually incompatibility issues. Otherwise any modern rig is free of timing problems.

CONCLUSION

So when it comes to digital pedals and modelling gear and even cheap 

wireless systems, go ahead and enjoy them. There simply are zero issues.

The human brain is set up to compensate so it can get a quick idea 

of things close, a bit of a distance and far away. 

Any more would make it too hard to tell how close a man eating 

predator is away from you. Which does of course mean if you 

heard a very long delay in your rig ...RUN !!! or it is will tear you pieces!!!
