Performs some needed preprocessing before base class function is called.
<p>
This function will take the position and number of samples requested and based on several factors will determine what position and number of samples is required from its parent. It will also try as best as possible to keep  the data streaming. This is so it can read from a device or a format that does not have random access. When this function is done it will call the <a class="el" href="classaflibAudio.html">aflibAudio</a> base classes function of the same name.

Sets the sample rate conversion factor.
<p>
This will set the sample rate conversion factor. Virtually any value, within reason, can be set. For instance to convert 22050 to 44100 a factor of 0.5 should be used. To convert 44100 to 22050 a factor of 2.0 should be used. This will change the factor that was set in the constructor. This function can also be used to change the final amplitude. This only applies to the small and large filters and not the linear mode.     </td>
