Inform base class that this object only supports 16bit signed data.

This overrides the virtual function in the base class. This algorithm works only on 16 bit signed data. Base class must convert the data.

<p>
Sets the input audio data configuration of an object.
<p>
This is a virtual function that derived classes can override if needed. It allows the caller to set the configuration of the audio data of an object. By default it saves the output audio configuration to be the same as the input data configuration that is passed in. This should be sufficient for most derived classes. For those classes that will have a change from the output to input config mapping then this function should be overriden and the output config processed and saved.

Sets parameters for the butterworth filter class.

This allows the user to change the filter parameters of the butterworth filter after the class has been setup. With this one could change the center frequency or bandwidth dynamically as data is streaming.     </td>
