An audio recording system has to meet some requirements to make a high quality record. One of many important requirements is the absence of noise during the recording sessions. This research is conducted in order to design a quality enhancement system for audio recording with the usage of wavelet noise reduction and gain adjustment methods. The wavelet noise reduction can eliminate noise generated from other sources of audio. The desired amount of noise for elimination can be configured through the usage of threshold in the noise reduction process. If the noise reduction output was not satisfactory in terms of signal power, the gain adjustment method can amplify the signal power. This application is able to reduce noise found in various audio records which were created in a less than ideal condition. The best noise reduction is given by using Symlet filter. It is also able to become an helpful tol in the analog ti digital conversion audio records. Keywords: Audio, Wavelet Noise Reduction, Automatic Gain Adjustment
