The indispensable need for alignment and optimization of sound systems has prompted this study. It tries to answer questions such as: What constitutes audio and frequency response components? Are they pragmatic? What are filters in this context? The work mainly focuses on improving an input audio signal to be free from shape glitch in order to circumvent unwanted audible peaks or anomalies in the final sound. Additionally, this study tries to offer operational flexibility per definition of an Audio Multitone Refiner. Because of their versatility, the signal analyzing tools Laplace transform, Fourier series, D.C. and transient analysis were employed to ascertain the realization of all constructed circuits in this study. ‘Casio fx7400G’ language was used during programming of the band pass filter, as were active filters.
