--- | Delay by certain number of samples

+-- There is a subtle difference between the function and the function @delaySnd@.
+-- The @delaySig@ is for delaying a signal on a micro level (the delay time have to be small)
+-- It's implemented with delay buffer in the csound. But @delaySnd@ is for delaying
+-- on macro level (the delay time can be big). It's implemented with scores and invocation
+-- of hidden instruments.
