# Vibration

# Intensity

The intensity parameter of a vibration determines the amplitude of the oscillations and thus how strong the vibration will feel. In addition to the slider, this value can be adjusted by pulling the upper border of the striped green area of the vibration block up or down with your mouse.

100%

# Intensity Fade

To create smooth transitions and soft vibrations you can use a fade effect to slowly increase the intensity value over time. Start by selecting a vibration block and select the “Fade in” panel underneath the intensity slider.

# Fade-in vs. Fade-out

Two options are available that define the placement of the effect: A fade-in is placed at the beginning of a block, and a fade-out is placed at the end. Combine both to achieve more complex patterns.

# Enabling and disabling

The toggle switch on the top right of the fade-in menu allows you to enable and disable the fade-in.

# Duration

You can choose how long the fade-in progression will take using the duration slider. Higher values can feel smoother and more subtle, while values are perceived more aggressive and steep.

Minimum

0 ms

Maximum

the total duration of the vibration block (- the duration of an intensity fade-out)

# Starting value

The initial intensity value from which the fade is starting. It can be used to transition between or match to proceeding blocks.

100%

# Non-linear Fades

In addition to linear fades, you can create non-linear intensity fades for more dynamic effects. The shape of the fade can be adjusted using the coefficient parameter.

# Coefficient

The coefficient determines the curvature of the fade. It can be adjusted through the slider or by dragging on the center of the fade visualization.

Minimum

-100%

Maximum

100%

A coefficient of 0% results in a linear fade. Positive values create a convex curve, while negative values create a concave curve. This allows for a wide range of fade shapes, from gentle easing to sharp, sudden changes in intensity.

# Frequency

The frequency parameter represents how many oscillations the actuators will complete every second. High frequencies can feel like a sharp buzz, whereas low frequencies can often be perceived like a deep rumble.

This parameter is not applicable to ERMs and LRAs: LRAs are driven at their natural frequency, and for ERMs, intensity and frequency are inherently coupled.

Maximum

500 Hz

Minimum

1 Hz

# Frequency Fade

Freuquency-Fade effects allow you to vary the Frequency value over time. Start by selecting a vibration block and select the “Fade in” panel underneath the Frequency slider. The effect is also often referred to as frequency-sweep.

# Fade-in vs. Fade-out

Two options are available that define the placement of the effect: A fade-in is placed at the beginning of a block, and a fade-out is placed at the end. Combine both to achieve more complex patterns.

# Enabling and disabling

The toggle switch on the top right of the fade-in menu allows you to enable and disable the fade-in.

# Duration

You can choose how long the fade-in progression will take using the duration slider. Higher values can feel smoother and more subtle, while values are perceived more aggressive and steep.

Minimum

0 ms

Maximum

the total duration of the vibration block (- the duration of an intensity fade-out)

# Starting value

The initial intensity value from which the fade is starting. It can be used to transition between or match to proceeding blocks.

Minimum

1 Hz

Maximum

400 Hz

# Duration

All blocks have a duration parameter, specifying the playback time. The value can be controlled through the slider or by pulling the right border of the block with the cursor.

Minimum

1 ms

Maximum

4000 ms

# Non-linear Frequency Sweeps

Similar to intensity fades, you can create non-linear frequency sweeps for more complex and dynamic effects. These are often called chirps.

# Coefficient

The coefficient for frequency sweeps works similarly to intensity fades. It determines the curvature of the frequency change over time.

Minimum

-100%

Maximum

100%

A coefficient of 0% results in a linear frequency sweep. Positive values create an accelerating sweep, while negative values create a decelerating sweep. This allows for a wide range of frequency change patterns, from gradual shifts to rapid frequency jumps.

# Waveform ⭐   Starter

The waveform selection determines how the actuators will be moved to render the vibration. There are three options: Sawtooth, Sine, and Square waves. All of them have different characteristics: Square waves are the sharpest and strongest of all the waveforms. They are capable of producing the most intense vibrations.

Sine waves are the smoothest of all the waveforms and generally minimize the auditive feedback.

Sawtooth waves combine some of the smoothness of sine waves with some of the sharpness of square waves. In addition, since they are asymmetrical, they come with directionality: Try out the Invert option in combination with the sawtooth wave!

Options

Sine Square, Sawtooth

# Invert

With this option, you can change the movements of your actuator to the opposite direction.

ERM

The excentric mass is spinning in the opposite direction.

LRAs and voice coils

As the vibration consists of repeated movements in opposite directions, inverting the vibration means that this oscillating movement will start in the opposite direction. This can be interesting when chaining two vibration blocks. While those are usually synchronized to ensure smooth transitions, you can use the invert functionality to create perceivable transitions or abrupt stops.
