In Reply to: Does ASRC (upsampling) hurt pass band ripple in general? posted by dave789 on July 24, 2015 at 05:03:31:
A reasonable implementation of ASRC should not produce FR variations all the way down to 350 Hz as shown. Nor the channel mismatch shown. It could be coming from the analog preamp section. It might also be an artifact of the measurement setup, e.g. a ground loop.
