HDCD CDs and transcoding

convOut=-af "hdcd, aresample, volume=replaygain=track, aresample"

Thanks for taking time to carry out further investigations and for providing the convOut command, especially as this is probably a minority use case!

The handful of albums I have with HDCD logo have album Replaygain values between -3dB and -6bB. As the HDCD filter is applying 6dB reduction I was thinking of removing Replaygain tags from the HDCD files as a further reduction shouldn’t be needed.
