Alternatively, we could have clipped the input value (to a different range, of course), and that is generally a little bit better, because float values which are out of the range of integer representation can produce arbitrary integer values, in which case we would no longer get true clipping. Now, we use another macro to compute the read index from the RecordPos and Distance: Obviously, the playback position must be the Distance in samples behind the record position; therefore, we subtract one from the other: The distance value is latched because it is produced by a control signal input, which potentially can receive events at any time, and we do not want the subtraction happening at times other than at audio-clock events. If we just subtract, the difference can turn out to be less than zero because our array is not a loop; its ends are not connected together. So we need to wrap the result: -1 must become N-1, -2 must become N-2, -3 must become N-3, and so on. 132 – REAKTOR CORE
So we include another macro for wrapping: Because we know that the difference cannot be smaller than –N+1 (because RecordPos is between 0 and N-1 and Distance is between 0 and N-1), wrapping can be implemented as simple addition of N: Let’s get back to our top level structure. Now that we have the write and read indices, we just need to perform reading and writing: Note that reading is happening after writing and that it’s clocked by the sampling-rate clock. Here’s a proposed test structure. Don’t forget to put an ms2sec converter into the Delay core cell and to set the Delay core cell to monophonic mode: REAKTOR CORE – 133
