Ok,

At the moment it only delays either the left or the right since there is no point in delaying both right? Basically it works just like a left right balance control. The UI displays the delay and whether it is being applied to the left or the right channel.

Also according to my calculations (333m/sec speed of sound) 1 meter is about 3ms away. So why do delay systems seem to have values in the tens of milliseconds (i.e. 10 metres = 30ms).

Do we need that much delay for time alignment or is say 2 - 3 metres enough for most people. I assume no one has a car wider than 3 metres.
