+//                for high-quality two-way communication.
+//                NetEQs packet loss concealment and signal processing
+//                capabilities are fully employed.
+// -fax         : The fax mode is optimized for decodability of fax signals
+//                rather than for perceived audio quality. When this mode
+//                is selected, NetEQ will do as few delay changes as possible,

+//                conference participant, a webinar, or a streaming application,
+//                this mode can be used to improve the jitter robustness at
+//                the cost of increased delay.
