FXAlg #970: 5 Band EQ
Stereo bass and treble shelving filters and 3 parametric EQs
Allocation Units:
3
This algorithm is a stereo 5 -band equalizer with 3 bands of parametric EQ and with bass and treble tone controls.
The user has control over the gain, frequency and bandwidth of each band of parametric EQ and control of the gain
and frequencies of the bass and treble tone controls. The controls for the two stereo channels are ganged.
Parameters:

In/Out
When set to ÒInÓ the tone controls are active; when set to ÒOutÓ the tone controls are
bypassed.
Bass Gain
The amount of boost or cut that the Þlter should apply to the low frequency signals in
dB. Every increase of 6 dB approximately doubles the amplitude of the signal. Positive
values boost the bass signal below the speciÞed frequency. Negative values cut the bass
signal below the speciÞed frequency.
Bass Freq
The center frequency of the bass shelving Þlters in intervals of one semitone.
Treb Gain
The amount of boost or cut that the Þlter should apply to the high frequency signals in
dB. Every increase of 6 dB approximately doubles the amplitude of the signal. Positive
values boost the treble signal above the speciÞed frequency. Negative values cut the
treble signal above the speciÞed frequency.
Treb Freq
The center frequency of the treble shelving Þlters in intervals of one semitone.
Mid
n
Gain
The amount of boost or cut that the Þlter should apply in dB. Every increase of 6 dB
approximately doubles the amplitude of the signal. Positive values boost the signal at
the speciÞed frequency. Negative values cut the signal at the speciÞed frequency.
Mid
n
Freq
The center frequency of the EQ in intervals of one semitone. The boost or cut will be at a
maximum at this frequency.
Mid
n
Width
The bandwidth of the EQ may be adjusted. You specify the bandwidth in octaves. Small
values result in a very narrow Þlter response. Large values result in a very broad
response.
