delay1 — Delays an input signal by one sample.
iskip (optional, default=0) -- initial disposition of delay-loop data space (see reson). The default value is 0.
delay1 is a special form of delay that serves to delay the audio signal asig by just one sample. It is thus functionally equivalent to the delay opcode but is more efficient in both time and space. This unit is particularly useful in the fabrication of generalized non-recursive filters.
