Stillwell Audio 1973 Help File Output Gain: Cut or Boost the output level to prevent clipping or increase volume respectively. Oversample: Higher Quality Anti-Aliasing Algorithm that can be employed on final renders. HPF or High Pass Filter: Allows frequencies higher than the specified amount to pass through, while filtering anything lower. Thus a cut at 160Hz will remove all frequencies below 160, leaving the rest untouched. A cut at 50 Hz helps ‘open up’ a mix, as most speakers cannot recreate these frequencies anyway, and they take up valuable headroom. Low Shelf: A shelving filter affects the level of a particular frequency by a fixed amount. In this case, the Low Shelf EQ can be used to cut or boost any one of four frequencies that comprise the low-end/bass of the spectrum. Here is a brief description of these frequencies and their practical mixing applications: 35Hz: Sub Bass Frequencies. For genres like Drum and Bass and Dub. Cut to reduce boom. 60Hz: Add/remove bottom end. Adds weight to bass and kick drums. Cut to reduce boom. 110Hz: Can add weight to bass,vocals and snares. Cut to tighten up low end. 220Hz: Can add body to the mix. Cut to reduce muddiness. Simply select the frequency you want to cut or boost and dial in the appropriate amount. Mid Bell: Similarly, the Mid Bell EQ can be used to attenuate (cut or boost) mid range frequencies. Here, we have a choice of 6 pre-selected frequencies to choose from. A brief description of these frequencies and their practical applications are as follows: 360 Hz: Can add body to vocals and tighten up pianos and guitars. Cut to reduce muddiness in the mid range. 780 Hz: Strings and keyboard instruments usually reside in this range. 1.6 Khz: Small boosts may add warmth. Hi hats and cymbals usually reside in this range. 3.2 Khz: As above. Cut or boost to taste. 4.8 Khz: Finger plucks/attacks and synthesizer and vocal harmonics usually reside in this range. 7.2 Khz: As above. It is important to note that a lot of these frequencies may overlap across the spectrum, so it is essential that you use the above notes as guidelines and trust your ears. High Shelf: Affects frequencies above a certain amount, in the case 12Khz. Boosting here can add air and brightness to single instruments and mixes. Double Right Clicking a knob returns it to its default position. Left Click a knob to manually enter in a precise value. The hit enter to disable the value readout. You can also left click a knob to bring up a visual readout of the values in Db. Hitting enter disables the value readout.
