Using the Graphic Equalizer effect
The Graphic Equalizer effect boosts or cuts specific frequency bands and provides a visual
representation of the resulting EQ curve. Unlike the Parametric Equalizer, the Graphic
Equalizer uses preset frequency bands for quick and easy equalization. The fixed Q settings
ensure that no drop outs exist at intermediate frequencies. You can space frequency bands
at intervals of one octave, one-half octave, or one-third octave.
The Graphic Equalizer effect is an FIR (Finite Impulse Response) filter, which maintains
phase accuracy—unlike an IIR (Infinite Impulse Response) filter, which can introduce
phase errors, adding a ringing quality to audio.
To use the Graphic Equalizer effect:
1 Select an audio range (Edit View) or track (Multitrack View).
2 In the Effects tab of the Organizer window, expand Filters, and double-click Graphic
Equalizer.
3 Set the desired options.
For more information, search for “Graphic Equalizer options” in Help.
Using the Notch Filter effect
The Notch Filter effect removes up to six user-defined frequency bands, in addition to
standard telephone DTMF tones. Use this effect to remove very narrow frequency bands,
such as a 60 Hz hum, while leaving all surrounding frequencies untouched.
