A system and method executed by audio processing software on one or more electronic devices in a computer system to process digital audio signals. The system comprises a digitizer for digitizing a received audio signal; and processor for performing a plurality of audio processing functions on the digitized audio signals, each of the audio processing functions having at least one programmable parameter, and wherein each of the audio processing functions are categorized and grouped as audio objects, and organized into a channel strip, the channel strip processing digitized audio signals for a particular received audio signal, and wherein, the audio objects are fixed in order, so that the digitized received audio signals are processed by a predefined number of N audio objects, and wherein the N audio objects occur in a fixed sequence, and further wherein, the N audio objects comprise a first subset of non-exchangeable audio objects and a second subset of exchangeable audio objects, such that any one or more of the second subset of audio objects can be exchanged by a replacement audio object, and further wherein when the audio processing functions are programmed, they can be saved without compiling the audio processing software.
