The Oxford DeNoiser
Description of Controls – DeHisser Section
“Cutoff” – This controls how far down the spectrum hiss removal is done. Can be set in the
range 3kHz to 15kHz.
“Reduction” – This sets how many dBs of hiss reduction will be applied, up to -24dB.
“Enable” – If Master Enable is also IN, this makes the DeHisser active using glitchless
switching.
Description of Controls – DeNoiser Detect Section
“Thresh” – This is the most critical control to get right. It sets the level of the threshold about
which noise reduction takes place. Frequency components below the threshold get attenuated,
whereas components above the threshold are left alone. If Thresh is set too high, signal will be
attenuated; if set too low, not enough noise will be removed.
