Abstract:

This research undertaking aimed to construct an amplifier controller which could enhance the flair of music from an input audio device. Specifically, the study sought to control the volume by amplifying the sound and balancing the audio pitch.

The study used experimental development method intended for the experimentation part and descriptive approach for the evaluator's assessment of the project.

Findings showed adequate results in terms of data processing and manipulation of the amplifier by the microprocessor, volume and pitch control, and output display in the seven segments.
