UP Sampling
Description
The Up sampling module is mainly used to get the input samples to a higher sampling rates after processing the audio at lower sampling rates.For example the bass of the audio can be processed at lower sampling rates and then taken to the higher sampling rates.
This module takes the upsample factor from the GUI parameters and upsample the input accordingly.
