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.
