The current study is concerned with assessing the sound quality of various audio codecs including ubiquitous de-facto standards. Formal listening tests were conducted based on the ITU﷓R Recommendation BS.1116 in order to provide an objective measure of sound quality. Codecs under test included de-facto standards that were commercially and non-commercially available, and the MPEG general audio. In addition, our recently updated codec was tested. Test items consisted of usual MPEG test sequences and other sensitive sound excerpts at the bitrate of 64 and 96 kbps stereo. Experimental results show that the sound quality of our newest codec outpaces that of most of other codecs.
