DC offset added with EQ
The original file was recorded through the AES input port from a Tascam DAT machine. The DC offset does not exist on the original file. Only after applying EQ to a segment does it show. The EQ in question was a 20Hz High Band Pass needed to remove noise. I wound up not using the EQ because I was not sure if the CD replication facility would reject the master with such a DC offset.
