Audio Effect Package
Introduction
The Audio Effects Package means that there is finally a comprehensive collection of
audio effects for the Casablanca system.
The effects can be roughly divided up into two groups:
1 Effects for sound editing, such as De-hummer, MaxVol, NoiseGate, which are primarily
used for sound correction
2 Effects such as Chorus, Delay, Hall, Vibrato, which are used for creative sound design
DeHummer
Reduces the static hum caused by the mains electricity supply. Depending on the
strength of the interference, it might be necessary to apply the effect several times.
Frequency: 50 Hz for the hum caused by the mains electricity network in Europe
60 Hz for the hum caused by the mains electricity network in the United States
Chorus
Creates a denser sound by mixing in additional slightly altered voices. The chorus can
also be used to breath some life into a monotonous sound.
Intensity: How strong an influence the effect will have (100% means maximum, 0%
means no effect)
Depth: Intensity with which the pitches of the secondary voices are changed (detuned).
Speed: Adjusts the oscillation of the pitches of the secondary voices.
Delay
Adds rhythmical echoes to the sound. The volume of the echoes fades out so they
get quieter over time. If you want to use this kind of effect, you should leave some space
at the end of the recording for the final echoes, since the effect is not able to lengthen the
recording of its own accord.
Intensity: How strong an influence the effect will have (100% means maximum, 0%
means no effect)
Decay: How quickly the echoes become quieter
Delay: The time that elapses between two echoes
Dynamic
Adjustment of volume differences. The Dynamic effect allows you to attenuate peaks
in the signal. Quiet sounds can be amplified or also suppressed. Imagine you have a recording that is generally very quiet but at some point contains a loud bang.
You will not easily be able to make this recording louder without over-amplifying the
bang. But the Dynamic effect allows you to do this!

Dynamic: Change the volume range
Echo
Generates echoes within a certain time range. Compared with the Delay effect, this effect
allows you to influence the number and distribution of the echoes directly. All the other
details described for the delay effect also apply to this effect - the echoes fade away
slowly and the recording is not lengthened in order to create space for the final echoes.
Intensity: How strong an influence the effect will have (100% means maximum, 0%
means no effect)
Echo from ... to: Times for the echoes
Echoes: Number of echoes to be generated
Filter
Filters (suppresses) frequency ranges in a sound. You could, for instance, use a lowpass filter to make a music recording sound distant.
Intensity: How strong an influence the effect will have (100% means maximum, 0%
means no effect)
Filter type: Filter characteristic curve, i.e. which range of frequencies is allowed to pass
Frequency: At what frequency the filter will begin taking effect
Flanger
A modulation effect that adds a lively variation to the sound.
Intensity: How strong an influence the effect will have (100% means maximum, 0%
means no effect)
Decay: Various sound variations are possible
Depth: Various sound variations are possible
Speed: Various sound variations are possible
Speed
The sound is detuned and at the same time changes in length. The principle is similar to
changing the playing speed of tape recorders or record players. If the pitch of the sound
is increased it will also become shorter. Similarly, if the pitch of the sound is decreased it
will become longer.
Factor: Percentage change in the pitch
Hall
Creates a spatial impression. The effect generates a multitude of sound reflections (echoes). The volume, density and tone quality of the reflections are changed over time. This
effect can be used to simulate the acoustic properties of various rooms.
Type: Various room types

Intensity: How strong an influence the effect will have (100% means maximum, 0%
means no effect)
Harmonic
Generates resonances at certain pitches. If harmonic pitches are stimulated, the
recording can be made to "sing".
Intensity: Strength of the effect
Tone: Fundamental tone for the chord
Chord: Chord preset
Tone control
Allows you to adjust the tone. This effect works in a similar way to the tone controls on a
hi-fi sound system. If, for example, the voice of the narrator in a recording is drowned out
by other sounds, you can improve the situation by slightly boosting the mid frequencies
whilst slightly reducing the treble and bass.
Low: Adjust the low frequency range
Mid: Adjust the mid frequency range
High: Adjust the high frequency range
TimeChange
The length of a sound can be lengthened or shortened by a fixed amount - the recording
is then stretched or compressed accordingly. No part of the recording is cut off. You can
use the TimeChange effect to adapt the music recording to the length of your video. The
effect, however, should only be used to make slight changes. Very strong changes, e.g.
as a result of applying the effect repeatedly, will quickly lead to losses in quality.
Change: Absolute change to the length in frames
Source: Fine-tuning for different signals
TimeStretch
The length of a sound is changed in percent. No part of the recording is cut off.
The same applies here as described for the TimeChange effect.
Stretch: Percentage change in the length
Source: Fine-tuning for different signals
Sway
Makes your recording "whine". This effect is similar to the sound a faulty cassette recorder makes. A short analysis takes place before the actual calculation is carried out.
Factor: +/- Percentage change in the pitch and speed
Waveform: Type of oscillation that is to be used
Frequency: How quickly you want the LFO to oscillate

MaxVol
Increases the sound to the maximum volume possible without distortion occurring.
During the first process step, the recording is checked to see whether there are sufficient
reserves left for changes to be made (the status bar does not increase during this process). The signal is then amplified during a second process step.
There are no settings options
NoiseGate
Fade out quiet parts of the recording. This can, for instance, be used to fade out the
volume of the background noise that can be heard in the pauses between the spoken
parts of speech recordings.
Attack: How quickly the fade-in and fade-out should occur
Threshold: The volume level below which you want the sound to be faded out
Normalize
Adjusts the sounds to a particular absolute level. The two processing steps already described for MaxVol also apply here.
Level: Target volume level
Phaser
A modulated comb filter that adds lively variations to a sound. As time passes, the sound
distorts and becomes clearer again. This kind of effect has been used, for instance, to
modulate the voices in science fiction films.
Intensity: How strong an influence the effect will have (100% means maximum, 0%
means no effect)
Depth: Controls the intensity of the effect
Speed: Controls the rate of modulation
Phono Convert
Corrects record-player recordings that have been recorded at a different speed.
Type: Playback speed / recording speed
Radio
Simulates the sound of old radios. The effect focuses on the limited range of pitch
of these kinds of devices and simulates various interference effects.
Preset: Type of radio
Retro
Adds distortion effects to a recording so that it sounds antique.
Noise Level: Volume of the blanket of sound

Noise Sway: Speed
Crackle: Intensity of crackling sounds
Reverb
Creates simple reverberation effects. In contrast with the Hall effect, this effect is based
on a simpler but quicker process. This effect is useful if you only want to give the sound a
slight spatial or echoic feel.
Level: Volume of the reverb effect
Decay: Density of the reverberation
Delay: Length of the reverberation
Robotize
Creates a metallic rasping sound. The Robotize effect uses disharmonic resonances
and can therefore be used to add a metallic characteristic to a sound.
Intensity: Clarity/intensity of the effect
Delay: Tone quality of the metallic sound
Telephony
The sound is modified so that it sounds like you are hearing it over the telephone.
Telephone transmission strongly reduces the quality of the sound of voices, particularly
when older telephones are used. The effect can be used to simulate this kind of loss of
quality.
Preset: Type of telephone
PitchShift
The pitch of the sound is changed. This effect can be used to subtly correct the pitch.
Although strong changes to the pitch unfortunately also diminish the sound quality,
it is nevertheless a lot of fun!
Intensity: How strong an influence the effect will have (100% means maximum, 0%
means no effect)
Pitch: Percentage change in the pitch
Source: Fine-tuning for different signals
Tremolo
A cyclical volume fluctuation. The Tremolo is suitable for such things as helicopter effects.
Amplification: Intensity of the volume change
Waveform: Type of oscillation to be used
Frequency: How quickly you want the LFO to oscillate

Vibrato
A cyclical pitch fluctuation. The Vibrato effect can, for instance, be used to create funny
voice effects. You could, however, also use it to create a police siren from a simple sinusoidal test sound.
Pitch: +/- Pitch change in %
Waveform: Type of oscillation that is to be used
Frequency: How quickly you want the LFO to oscillate
