I found this entry due to the fact I was looking to solve my own query. On car ampl they show low-pass & high pass filters. From the research I did to find out what this meant I found a response that puts it this way. Sound is made up of a large spectrum of frequency. The filters is designed to attenuate or reduce the audible level of the band of sound that you want to remove. For a sub-woofer you would want to attenuate or remove the highs thus I guess you could refer to this as conditioning. To analyze a signal it must be analyzed and your amp does this. Hence you have processing.
