Abstract: A digital processing system for monitoring sound effects produced by codecs during a signal processing session is provided. The digital processing system comprises, a sound source for producing signals for processing, a sound monitor having at least two channels for monitoring sound quality of the sound source, a sound recorder for recording the sound source, a playback device for playing a recorded file of sound produced by the sound source, a codec simulator for simulating sound effects produced by codecs, a plurality of codecs for compressing and decompressing sound files and a control interface for sampling, adjusting, and implementing an optimum codec based on monitoring of sound effects produced by codec simulation. A user controlling the system may monitor sound variances produced by any one of the plurality of codecs affecting the quality of sound from the sound source during signal processing of the source sound without interruption of the signal-processing session.

Abstract: An electronic processing device for producing digitally processed audio-signal effects is provided. The electronic processing device comprises, an audio-signal input circuitry for receiving an audio input signal from a peripheral audio device, an audio-signal output circuitry for outputting the received audio-signal, the signal comprising a throughput signal after signal processing, a digital signal processor for applying audio-signal effects to the throughput audio-signal, one or more memory slots for receiving one or more modular memory components and an input control mechanism for controlling parameters of the throughput audio-signal. The one or more modular memory components are used as storage for externally sourced audio-signal effects such that when the one or more memory components are plugged into the electronic processing device, the processing device may utilize the effects applications stored on the one or more memory components in the processing of the throughput audio-signal.
