Two-channel input audio signals are processed to construct output audio signals by decomposing the two-channel input audio signals into a plurality of two-channel subband audio signals. Should the information stored exceed the parameters, an alert is sent to the network. Moreover, electronic modules which comprise large surface area silicon carriers with multiple chips face mounted thereon are designed such that integrated silicon cooling modules are rigidly bonded to the back surfaces of such chips to increase the structural integrity of the silicon carriers.
