-  // for i) voice, ii) FAX or iii) streaming. In Voice mode, NetEQ is
-  // optimized to deliver highest audio quality while maintaining a minimum
-  // delay. In FAX mode, NetEQ is optimized to have few delay changes as
-  // possible and maintain a constant delay, perhaps large relative to voice
-  // mode, to avoid PLC. In streaming mode, we tolerate a little more delay
-  // to achieve better jitter robustness.
