ABSTRACT:
An audio data file analyzer apparatus includes: analyzers for analyzing at least one of physical characteristics of an audio signal to produce an analyzed resultant data the at least one physical characteristic possibly including a continuous time duration of the audio signal, a control data input for providing a control data for an audio data file; a reference code generator for producing a reference code from the analyzed resultant data and the control data; a reference code storage for storing the reference code; a reference code input for providing a specific reference code requested by an operator, and a reference code comparator for comparing the specific reference code, a newly introduced reference code which are produced by the reference code generator from other audio signal, or combination of the specific reference code and the newly introduced reference code with the reference code. Furthermore, while a multiplicity of the audio data files are stored in libraries controlled by a library controller, a new audio data file carrying desired physical characteristics can be produced from the audio data files of the libraries with an audio data processor.
