CCITT G.722 WIDEBAND CODING RECOMMENDATION
S.M.F. Smyth, John V McCanny, Paul Challener · 1988
The subjective performance of the G.722 7kHz wideband speech coding recommendation using music signals is described. A number of audible distortions s pecific to music signals were found to be present in realtime evaluations of the coder. As a result, three modifications are proposed which are found to improve the performance for music signals. These modifications are compatible with the G.722 system configuration.
