Abstract

A multi-parameter physical audio signal decoding system includes an audio capturing device, a signal pre-processor, a signal decoder, a data modulator and a display device. The audio capturing device receives audio signals, and transforms them into digital signals in real time. The digital signals are transmitted to the signal pre-processor. The signal decoder decodes the digital signals. The data modulator removes signal noises. The display device displays the modulated digital signals. In a non-real-time decoding process, an audio file recorded with physical signals is transmitted to the pre-processor to proceed the decoding process.
