Abstract

The title of the project is "Audio Room Acoustic Tuning System". The system aimed to detect whether the sound play from speaker can achieve a balanced stereo sound effect. The scope of the project is to solve the problems of was used to develop in tuning the stereo sound system. In this project, the MAT LAB was used to develop the main software to analyze the audio. Hardware used includes, a small speaker and a microphone which are used to generate and receiving sound for the purpose of audio analysis. The process of analysis starts with generating the reference audio signal with the frequency range from 20 1--1z to 20 kHz. The reference sound is applied to the loudspeaker and the recording audio signal is picking up by the microphone. The sound analysis software is then invoked to determine whether the acoustic sound has achieved a balanced stereo sound effect.
