3. Digging deeper with Kilohearts Slice EQ

1 Now we’re going to start EQ-ing by selecting several EQ points over the full frequency range. First select the Edit tool, top left as shown above.

2 Now select the filter type. This is one from the six options on the right at the top of this area: hi-pass, low-pass, hi-shelf, low-shelf, peak and notch.

3 A further seventh option looks like a magic wand. Selecting this will automatically select a filter type depending on where you want to make your EQ adjustment on the frequency range. If you are working from 20-30Hz a hi-pass filter will be selected; from 31-70Hz a low-shelf (as shown).

4 From 70Hz to 7kHz you get a peak edit, and up to 15kHz a hi-shelf will automatically be selected. Above 15kHz and low-pass will be selected. Basically Slice is choosing the relevant filter type according to frequency position.

5 You can click and drag any of your newly-created points up and down to increase or decrease gain, or left and right to edit the cutoff frequency which is shown at the bottom in blue (which also shows the musical note value – F#5 here).

6 Similarly, you can see how much boost or cut is applied as you click and drag a point with a blue figure on the dB scale on the right (above the line for positive gain as shown, below for negative cut).

7 In order to adjust the resonance – the emphasis of the filter cutoff frequency point or Q – press Option while you are dragging the point up or down (or use your scroll or mouse wheel or trackpad).

8 Similarly you can change the rolloff of the slope – which ranges here from 6dB/octave to 96dB/octave. Press the Control or Command key while dragging the filter.

9 You can also adjust the value of multiple filter points by drag-selecting. Place your mouse on the screen away from the points and simply drag it across them to select multiple points as shown.
