DC Filter
The DC Filter is a core module provided on every CEDAR Cambridge system and removes DC offsets by offering a high-pass roll-off of 12dB/octave at any user-defined frequency in the range 1Hz - 20Hz. Because this improves the signal modelling used elsewhere in CEDAR Cambridge, it is invaluable when used before dynamics processes as well as restoration modules such as Declickle-2, Vintage Decrackle, Auto Dehiss, NR-4 and NR-5. It also increases signal headroom, and allows you to apply higher gains to output signals if desired.
Users may place the DC Filter anywhere in the signal chain, and can determine which channels are affected by the filter. A convenient display indicates the magnitude of any DC offset identified and, when desired, removed by the system.
