(8.D.2.3) Interleave
- Catherine Spain
Overview
Interleaves multiple audio signals
Discussion
The interleave module takes N audio inputs and produces a single output, where the N input signals are interleaved together. This module allows for different signals to be mixed into a single "wire,", which is useful when creating layouts, as a single processing path can represent parallel channels. Each input pin can have an arbitrary number of interleaved channels. The output contains all of the channels on the first input pin followed by all of the channels of the second input pin, and so on, for all input pins. There are no restrictions on the number of channels or the blockSize, though the blockSize of all inputs must be the same.
