Delays are a powerful tool in Unity, allowing you to create a variety of effects, from simple echoes to complex reverberation. However, using delays effectively can be tricky, especially when it comes to avoiding unwanted feedback and creating a cohesive soundscape. One way to achieve this is to use a void in delays. A void is a point in time where the delay signal is completely cut off, allowing the original sound to pass through unaffected. This can help to prevent feedback and create a more natural-sounding delay effect.
To create a void in a delay, simply set the Feedback parameter to 0. This will stop the delay signal from being fed back into itself, creating a clean break in the delay effect. You can also use the Dry/Wet parameter to control the balance between the original sound and the delayed sound. A higher Dry/Wet ratio will result in a more noticeable delay effect, while a lower Dry/Wet ratio will create a more subtle effect.
Using voids in delays can be a great way to add depth and dimension to your sounds. By controlling the Feedback and Dry/Wet parameters, you can create a variety of delay effects, from simple echoes to complex reverberation. Experiment with different settings to find the sound that best suits your needs.
Setting the Delay Time
The “Delay Time” parameter controls the length of the delay effect. It represents the amount of time between the original signal and the delayed signal. A shorter delay time creates a tighter, more slap-back-like effect, while a longer delay time creates a more spacious, ambient effect. The “Time” field in the Delay component allows you to set the delay time in milliseconds. You can enter a specific value or use the parameter’s slider to adjust the delay time interactively.
Delay Time Range
The acceptable range for the delay time depends on the sample rate of your audio project. Higher sample rates allow for longer delay times without introducing audible artifacts. Here’s a table that provides general guidelines for the delay time range:
| Sample Rate | Delay Time Range |
|---|---|
| 44.1 kHz | 0 to 200 milliseconds |
| 48 kHz | 0 to 220 milliseconds |
| 96 kHz | 0 to 440 milliseconds |
| 192 kHz | 0 to 880 milliseconds |
Choosing the Right Delay Time
The optimal delay time for your application will depend on the desired effect. For example, a short delay time (10-50 milliseconds) can create a subtle thickening of the sound, while a longer delay time (100-200 milliseconds) can create a more noticeable echo or reverb effect. Experiment with different delay times to find the one that best suits your needs.
Setting the Dry/Wet Mix
The dry/wet mix controls the balance between the original (dry) signal and the delayed (wet) signal. A 100% dry mix will result in only the original signal being heard, while a 100% wet mix will result in only the delayed signal being heard. Most often, you’ll want to use a blend of both, allowing the original signal to retain some of its clarity while adding depth and space with the delayed signal.
6. Tips for Using the Dry/Wet Mix
Here are some tips for using the dry/wet mix effectively:
- Start with a 50/50 mix and adjust from there to taste. Different styles of music and instruments will require different dry/wet ratios.
- Use a lower dry/wet ratio (e.g., 70/30) for subtle ambiance or space.
- Use a higher dry/wet ratio (e.g., 30/70) for more pronounced delays or echoes.
- Use automation to adjust the dry/wet mix over time, creating dynamic changes in the delay effect.
- Experiment with different dry/wet ratios on different instruments to create unique soundscapes.
- Use a spectrum analyzer to ensure that the delayed (wet) signal is not overpowering the original (dry) signal in the frequency spectrum, leading to muddiness.
| Dry/Wet Ratio | Effect |
|---|---|
| 100% Dry | Only the original signal is heard |
| 50/50 | Equal balance of original and delayed signals |
| 70/30 | Subtle ambiance or space |
| 30/70 | Pronounced delays or echoes |
| 100% Wet | Only the delayed signal is heard |
Controlling the Delay with Parameters
The Void In Delays effect offers a wide range of parameters that allow you to customize the delay effect to your liking. By tweaking these parameters, you can control the delay time, feedback, dry/wet mix, and more.
Here’s a breakdown of the key parameters:
Delay Time
The Delay Time parameter determines the length of the delay. You can adjust this parameter to create anything from a short slapback delay to a long, ambient delay.
Feedback
The Feedback parameter controls the amount of feedback in the delay. This parameter can be used to create a variety of effects, from subtle echoes to long, sustained feedback loops.
Dry/Wet Mix
The Dry/Wet Mix parameter controls the balance between the dry (unprocessed) signal and the wet (processed) signal. This parameter allows you to create a subtle delay effect or a more pronounced effect that completely replaces the dry signal.
Filter
The Filter parameter allows you to add a low-pass or high-pass filter to the delay. This parameter can be used to shape the tone of the delay and create a variety of different effects.
Modulation
The Modulation parameter allows you to modulate the delay time using an LFO. This parameter can be used to create a variety of rhythmic delay effects, such as a dotted eighth note delay or a syncopated delay.
Sync
The Sync parameter allows you to synchronize the delay time to the tempo of the song. This parameter can be useful for creating delays that are in time with the music.
Using Multiple Delays
To use multiple delays, you will need to create multiple Delay components and assign them to the same GameObject. You can then control the delay time, feedback, and mix of each delay individually.
To do this, follow these steps:
1. Create a new GameObject.
2. Add a Delay component to the GameObject.
3. Set the delay time, feedback, and mix of the Delay component.
4. Repeat steps 2-3 for each additional delay you want to use.
5. In the inspector, you can see the list of all the Delay components that are assigned to the GameObject.
| Property | Description |
|---|---|
| Delay Time | The time, in seconds, between each delay. |
| Feedback | The amount of the delayed signal that is fed back into the delay. |
| Mix | The mix between the original signal and the delayed signal. |
By using multiple delays, you can create complex delay effects with multiple taps. For example, you could create a delay effect with a short delay time and a high feedback value to create a slapback delay, or a delay effect with a long delay time and a low feedback value to create a spacious reverb effect.
Advanced Delay Techniques
Filtering Delays
Delay filters allow you to shape the frequency response of your delayed signal. By using a low-pass filter, you can create a warm, mellow sound, while a high-pass filter will produce a brighter, more metallic effect. You can use band-pass filters to isolate specific frequency ranges for delay.
Feedback Delay
Feedback delay involves sending a portion of the delayed signal back into the delay itself. This can create a variety of effects, from subtle ambience to chaotic feedback loops. By controlling the feedback amount and delay time, you can create a wide range of sounds.
Cross Delays
Cross delays involve splitting the input signal into two or more parallel paths, delaying them separately, and then mixing them back together. This can create a sense of space and movement, as the delayed signals interact with each other.
Ping-Pong Delays
Ping-pong delays pan the delayed signal back and forth between the left and right channels. This can create a wide, spacious effect, as the delayed signal bounces around the stereo field.
Multi-Tap Delays
Multi-tap delays create multiple delayed copies of the input signal, each with its own delay time. This can produce a complex, layered effect, as the different delays interact with each other.
Reverse Delays
Reverse delays play the delayed signal backward. This can create a unique, ethereal effect, as the sound seems to move in reverse.
Modulated Delays
Modulated delays use an LFO or other modulator to vary the delay time. This can create a variety of effects, from subtle warbling to extreme pitch shifting.
Synchronizing Delays to Tempo
Synchronizing delays to tempo ensures that the delayed signal stays in time with your music. This is especially important for creating rhythmic delay effects.
Ducking with Delays
Ducking with delays is a technique where one delay is used to create a volume envelope on another delay. This can create a pumping effect, as the second delay is attenuated whenever the first delay is active. The following table provides additional details about Advanced Delay Techniques:
| Technique | Description |
|---|---|
| Filtering Delays | Filter the delayed signal to shape the frequency response. |
| Feedback Delay | Send a portion of the delayed signal back into the delay to create feedback loops. |
| Cross Delays | Split the input signal into multiple delays and mix them back together. |
| Ping-Pong Delays | Pan the delayed signal back and forth between the left and right channels. |
| Multi-Tap Delays | Create multiple delayed copies of the input signal with different delay times. |
| Reverse Delays | Play the delayed signal backward to create an ethereal effect. |
| Modulated Delays | Use an LFO or other modulator to vary the delay time to create pitch shifting effects. |
| Synchronizing Delays to Tempo | Set the delay time to match the tempo of the music. |
| Ducking with Delays | Use one delay to modulate the volume of another delay to create pumping effects. |
How To Use A Void In Delays Unity
In Unity, a void is a method that does not return a value. It is commonly used for methods that perform an action, such as setting a variable or calling another method. When using a void in delays, it is important to understand how the delay works and how it affects the execution of your code.
The delay function takes a float parameter, which specifies the number of seconds to delay the execution of the code. The code that is placed inside the delay function will not be executed until the specified delay time has passed. This can be useful for creating timed events or for sequencing the execution of code.
When using a void in delays, it is important to be aware of the following:
- The delay function does not block the execution of the code that follows it. This means that the code that is placed after the delay function will continue to execute immediately, even if the delay time has not yet passed.
- The delay function is not executed on the main thread. This means that the code that is placed inside the delay function will not be executed until the next frame is rendered.
