Where is the filter option for adjust 15Khz low pass, and highpass. As i see low pass is constantly at around 16000, may be 16500 Hz and that`s all. Do you plan to put sliders, so user can obtain desired frequencies?
They designed it to be automatic based on the target destination. For streaming, it depends on the codec and bit rate. For FM or HD, they have their own optimal settings. The big push for BAO is to make things simple and not have an over-abundance of settings. My guess is there's no plans for this to be a setting.
