Abstract: 

In modern telecommunication systems the channel bandwidth and the quality of the reconstructed decoded audio signals are considered as major telecommunication resources. New speech or audio coders must be carefully designed and implemented to meet these requirements. EVS and OPUS audio coders are new coders which used to improve the quality of the reconstructed audio signal at different output bitrates. These coders can operate with different input signal type. The performance of these coders must be evaluated in terms of the quality of the reconstructed signals. The MOS and the PEAQ evaluation methods are nominated in this paper to examine the quality of these output decoded signals. The quality evaluation test achieved by using clean record signals (noise free) for individual oriental and orchestral instruments. These evaluation methods proved that the EVS and OPUS audio coders provide high audio quality for various categories of musical instruments. The OPUS has the highest encoding quality than the EVS for different musical instruments at different output bitrates.
