Description
MPEG surround is one of the most popular multichannel audio coding standards used today. In producing quality sound, there
are several parts that are influential, but those that are directly related to sound reproduction, one of which is the method of
downmixing, mixing the right channels will improve the quality of the sound produced. Because this research is closely related
to data computing, the Matrix Laboratory (MATLAB) application is used. There are 2 stages carried out in the MATLAB
application, namely the encoding and decoding process. In the encoding process in MATLAB, each audio channel is set
according to a previously designed scheme. The results of this encoding are then decoded, so that the ODG value of each tested
audio channel is obtained. In his presentation, the design and analysis of several domnmixing schemes was carried out. There
are 5 schemes tested and to determine the performance of each scheme, these schemes are tested at high bitrates, from the
range of 1000 Kbps to 2000 Kbps. Based on the test, it was found that the effect of increasing the bitrate is directly proportional
to the resulting audio quality. During testing Scheme-5 has a better level of stability among all downmixing schemes and the
average percentage increase in Objective Difference Grade (ODG) for all audio samples is 9.6927 %.
