EQ & Filtering A Level Music Tech

Equalisation is

• Making the sound equal

• is the process by which different frequency ranges are increased or decreased in volume.

• is the process by which different frequency ranges are increased or decreased in bandwidth

• a sequel to the film "The Equaliser"

Centre Frequency is...

• the centre of the cut off point

• the centre of the sound

• the mid-point of a band pass filter.

• the mid-point of a high cut filter

The cut off frequency is

• the point at which the frequency is filtered

• the point at which the filter begins to save frequencies

• the point at which the filter begins to add frequencies

• the point at which the filter begins to remove frequencies

Low Pass Filters remove frequencies that are

• above a cut off frequency

• below a cut off frequency

• same level as a cut of frequency

• beyond the level of human hearing

High Pass Filters remove frequencies that are

• above a cut off frequency

• below a cut off frequency

• same level as a cut off frequency

• sounding too low

Band pass filters are a

• bell curve around a high frequency.

• sharp spike around a centre frequency.

• bell curve around a centre frequency.

• bell curve around a low frequency.

A notch filter is used to

• add a notch filter

• notch up the sound

• add a specific frequency

• remove a specific frequency

Resonance is when the

• frequencies around the high frequency are boosted.

• frequencies around the cut off frequency are boosted.

• frequencies around the low frequency are boosted.

• frequencies around the band pass frequency are boosted.

Parametric EQs will show a..?

• overall curve which is created by combining all of the filters

• overall curve which is created by selecting a few of the filters

• nice pattern

• parametric graph

Graphic EQs use a bank of filters which are used to

• control the bass frequencies

• represent a true sound

• individually boost or cut specific parts of the frequency spectrum.

• control the treble frequencies
