This section discusses examples which illustrate advanced module design techniques. The modules are part of the Examples module library introduced in Section 2 Scaler Smoothed Module Example. In addition to the scaler_smoothed_example_module.m, the this library contains the following:
...
— Simple scaler. This module demonstrates how to support multiple input and output pins each with, possibly, a different number of channels.
peak_hold_example_module.m
...
— Similar to a level meter in that it measures the peak signal level. This module demonstrates how to allocate arrays and update array sizes within the module's prebuild function. A fixed-point version of this example is also provided: peak_hold_example_fract32_module.m.
fader_example_module.m
...
— Front-back fader which pans a signal between two different outputs. This module demonstrates compiled subsystems, that is, how to build a new module class out of a subsystem. A fixed-point version of this example is also provided: fader_example_fract32_module.m.
downsampler_example_module.m
...
— Downsampler which keeps 1 out of every D samples; no filtering is performed. This module demonstrates how to operate on arbitrary 32-bit data types as well as changing the output block size and sample rate.
lah_limiter_example_module.m
...
— Look ahead limiter delivered as a compiled subsystem. This module demonstrates some advanced features of compiled subsystems including initializing internal module variables and clarifying wire buffer usage.
The example library is found in the <AWE>\AWEModules\Source\Examples directory. Run the main script make_examples.m to generate code for the entire library.

This example is contained in the file scaler_example_module.m. It is equivalent to scaler_module.m provided in the Deprecated module library. This module implements a straightforward linear scaler without any smoothing. The module scaler_smoothed_example_module.m implements linear scaler with smoothing. The module has single input pin and single output pin with arbitrary number of channels. This module illustrate the basic components of Audio Weaver module.
