Why we need guard traces for critical signals like video or audio analog signals....

is it really plays good role in eliminating interference... or any other remedy is there?😁

Yes, Guard traces do help a lot in reducing adjacent channel interferences in analog signals. It depends on your interference level requirement. If it is very strict, you may surely need a guard trace. If not, just keeping the traces a few mms apart should suffice.
