Common Audio Effects
2nd Order Graphic Equalizer is similar to the one you might have in your stereo system. It employs 2nd-order band pass filters and emulates an analog equalizer. You can use it to adjust the frequency characteristics of the sound and to compensate the frequency response drawbacks of your loudspeakers or headphones.
Possibilities:
2nd Order Graphic Equalizer can alter the frequency spectrum of sound by boosting or cutting the selected frequency bands. You can increase or decrease the volume of frequency bands and see the visual representation of the overall EQ curve.
Description
Band boost/cut sliders. Each of the ten sliders corresponds to the boost or cut factor that will be applied to the specified frequency band. +10dB means that you are increasing the volume of the band a bit more than three times. –10 dB means that you are decreasing the volume accordingly. The actual value of the frequency band volume.
Amplitude-frequency characteristic graph. Displays how the input spectrum of the signal is modified. You can experiment with the settings by moving the sliders and control the expected result by watching this graph. The graph is updated each time you release a slider.
Band Pass Filter (available in full version only) effect is useful for amplifying or even extracting some parts of musical composition such as voice or musical instruments. This filter is applicable to a definite frequency band only. It preserves a definite range of frequencies (that is a band) while attenuating all the others. You can set the center frequency of the band and its width.
Possibilities
Band-pass BW Filter restricts all the frequencies higher and lower than the specified band and is useful for isolating or boosting a particular frequency range (e.g. of voice). Also you can mix dry signal with wet one (passed through the filter).
Description
Dry Out fader indicates percentage of input signal to be directed unaltered to the output. E.g. when Dry Out slider is set to 50%, the output signal will be the sum between half of the input signal intensity and the result achieved by processing of the input signal with current effect. When Dry Out slider is set to 0%, the output signal will be only the result achieved by processing of the input signal with current effect.
- Wet Out fader regulates how much of filtered sound is mixed to the output.
- Center Frequency fader is used to define the center frequency of the band. There is the maximum output at this frequency.
- Band Width fader is used to set the width of the frequency range.
- The real graph of amplitude-frequency characteristic shows how the spectrum of the input signal is modified. The graph is updated each time you release a slider.
Band Reject Filter (available in full version only) is useful for removing any part of sound spectrum such as voice or musical instruments. This filter is intended to obliterate a definite frequency band while preserving all the others. You can set the center frequency of the band and its width. Also known as a Notch filter this filter is the opposite to Band Pass and can be used to remove 50 or 60 Hz noise component (that is generated by electric sources) from composition sound.
Possibilities
The band-reject filter attenuates the selected frequency band and is often used to remove some narrow-bandwidth noise such as amplifier/microphone feedback or 60/50 Hz electrical hum. As it has wide possibilities you can also use it to remove any part of sound.
Description
Dry Out fader indicates percentage of input signal to be directed unaltered to the output. E.g. when Dry Out slider is set to 50%, the output signal will be the sum between half of the input signal intensity and the result achieved by processing of the input signal with current effect. When Dry Out slider is set to 0%, the output signal will be only the result achieved by processing of the input signal with current effect.
- Center Frequency fader is used to define the center frequency of the band. At this frequency the output will have minimum volume.
- Band Width fader is used to alter the width of frequency range.
- The real graph of the amplitude-frequency characteristic shows how spectrum of input signal is modified. The graph is updated each time you release a slider.
High Pass Filter (available in full version only) is used for high frequencies extracting. It allows cutting drums and similar low-frequency components while accenting high-frequency ones such as voice.
Possibilities
This effect mixes amplified high frequencies with the input signal. It allows to attenuate or even delete "hollow" sounds such as drums and bass-instruments. It can be used to correct the amplitude-frequency features (e.g. of tape-recording). The resulting gain-frequency characteristic is displayed by means of graph.
Description
Dry Out fader indicates percentage of input signal to be directed unaltered to the output. E.g. when Dry Out slider is set to 50%, the output signal will be the sum between half of the input signal intensity and the result achieved by processing of the input signal with current effect. When Dry Out slider is set to 0%, the output signal will be only the result achieved by processing of the input signal with current effect.
High Out fader is used to adjust the volume of the high frequency component mixed with the output signal.
Cut Off Freq fader is used to set the frequency border.
The real graph of an amplitude-frequency characteristic shows how the spectrum of the input signal is modified. The graph is updated each time you release a slider.
Limiter (available in full version only)
When experimenting with effects users might set incorrect parameters correlation and as a result the processed signal amplitude could exceed its permissible value. In such a situation sound card cannot reproduce the whole signal amplitude. As a result the signal gets clipped and distorted. Limiter is intended to fix the problems of this kind by signal scalaring within possible values.
Possibilities
Limiter allows to avoid signal amplitude limitations arisen due to wrong parameters setting of complex effects. Distortion compensation is achieved by a temporary decrease of signal volume. For more efficiency it’s recommended to use Limiter after applying other complex effects. This lets get rid of amplitude distortions under any parameters of previously applied effects.
Description
- Attack time – is used to define effect reaction speed to volume increase if it exceeds allowable threshold. Low values might cause unnatural sounding, while the greater ones could clip the signal during adaptation.
- Release time – is used to adjust the holding time of attenuated volume. Under low values you may observe the sound croaking. Although greater values might cause the signal sound faintly.
Low Pass Filter (available in full version only) extracts low-frequency components from music. It allows to create such famous effects as Bass Boost and Super Bass. It can be used to delete noise, voice or other high-frequency sounds while accenting different low-frequency components such as drum and bass instruments.
Possibilities
This effect allows to create such popular elements as Bass Boost and Super Bass. If there is some noise in a composition (for example microphone-noise or tape-recording-noise), it can be deleted almost completely with the help of this filter. It also allows to accent "hollow" sounds such as drum and bass instruments. The filter can be used to correct the amplitude-frequency features of sounds (e.g. recording from the microphone or low-quality sound card). The resulting gain-frequency response is displayed by means of graph.
Description
Dry Out fader indicates percentage of input signal to be directed unaltered to the output. E.g. when Dry Out slider is set to 50%, the output signal will be the sum between half of the input signal intensity and the result achieved by processing of the input signal with current effect. When Dry Out slider is set to 0%, the output signal will be only the result achieved by processing of the input signal with current effect.
- Bass Out fader is used to adjust the volume of the bass component mixed with the output signal.
- Cut Off Freq fader is used to set the Low Pass BW Filter working frequency range.
- The real graph of an amplitude-frequency characteristic shows how the spectrum of the input signal is modified. The graph is updated each time you release a slider.
