stdout.wav -mono -simple | QAAC
Work with a simple wav header, with a WAVE_FORMAT_EXTENSIBLE header (default) the channel mask can be other than 4 (mono center channel).
Remember: the undocumented switch "-mono" extract the center channel from a multichannel input or left channel from stereo input, don't make a downmix from input channels.
