Since the emergence of ChatGPT at the end of 2022, the release of various AI products has revolutionized how people work. Those who actively use AI products have reported significantly higher work efficiency than those who do not. According to 2023 statistics, 73% of US companies already use AI in their work, and 79% say that using AI will be critical to their success over the next two years. Therefore, it is becoming essential to study AI products related to one's work and to adopt an attitude of actively using them.
While many people are familiar with language models and image generation tools, and plenty of material is available, few good articles explain audio generation tools. This guide fills that gap, providing a comprehensive overview of an AI sound effect generator and how AI sound effects can be utilized. After reading this guide, you'll have a deep understanding of this unique tool and be able to create sound effects with an AI sound effect generator, enhancing your work efficiency in a previously unexplored way.

What is an AI sound effect generator?
An AI sound effect generator is software that generates sound effects based on user-provided input through an artificial neural network. The most common type is a text-to-sound effect generator, which takes a text prompt describing a sound as input and generates a corresponding sound effect. These generators can produce an infinite variety of sounds, including those that don't exist in the real world. This capability is due to artificial neural network learning, which generates sounds based on text by being trained on large amounts of text and audio pairs. These tools democratize sound production - allowing more people to create sounds and contributing to the development of more creative and immersive content.

How does an AI sound effect generator work?
To create an AI sound effect generator, which is also known as a AI sound effect generation model, it is necessary to design an architecture of the generator containing billions of artificial neurons and train these neurons to generate sound effect waveforms based on specific inputs.
Initially, large dataset of sound effects should be prepared. The cleaner the quality of the sound effects included in the dataset and the more detailed the accompanying descriptions, the better the performance of the generator will be after training.
Next is the model training phase. Before starting the full-scale training, a portion of the data is used to conduct various experiments to determine the structure of the generator that delivers the best performance. Once the optimal structure is identified, the large-scale data training begins. There are different structures for generators, but two commonly used ones are the auto-regressive architecture, which continuously creates the next sound snippet based on the previous waveform to complete the waveform, and the diffusion architecture, which generates a pleasant waveform from a random waveform.
Once the model training is complete, now you have a generator capable of freely creating sound effects based on text! During the inference stage, research is conducted on methods to utilize the model such as generating sound effects more quickly or specifying the style of the sound effects.
Benefits of an AI sound effect generator
An AI sound effect generator offers several advantages that traditional stock sound libraries or sound editing tools cannot provide, including:
- Comprehensive detail: Instead of selecting from a limited database, it allows for the generation of highly detailed and specific sound effects tailored to particular situations by varying the inputs.
- Time-saving: By using an AI model, you can obtain the appropriate sound effects within seconds, enabling faster audio work compared to searching multiple websites or recording sound effects yourself.
- License-free: Depending on the service, you can be granted complete usage rights and ownership indefinitely. This allows you to freely use the sound effects regardless of the number of contents or purposes.
- Creativity boost: It can generate an infinite variety of sound effects, leading to the creation of innovative sound effects that users might not have imagined.
- Scalability: Its ability to generate sounds quickly in parallel makes it useful when a large number of sound effects are needed. Companies and products can provide customized sound effects to many users efficiently.
Popular applications and use cases of AI sound effect generators
- Content Creation
Users who do not have an personal sound library and thus have limited access to sound effects can generate a wider variety and more detailed sound effects. They can apply these sound effects to various content and derivative works without copyright concerns.
- Prototyping
In fields like AAA films or games where professional musicians and sound designers perform sound work, AI sound effect generators can be used during the intermediate stages to quickly add sounds and test how they fit with other elements before the final sound work. This reduces the number of large-scale sound work sessions and allows all members of the studio to participate in the sound work.
- Responsive Generation
AI sound effect generators are extremely useful in situations where sound effects need to be generated instantly. Since they can create sound effects without human intervention, they can provide sound effects in response to the actions or reactions of users playing games or using apps. For example, if a user creates a custom weapon in a game, the weapon's information can be automatically input into the generator to create the corresponding sound effect.
Controversies surrounding AI sound effect generators
As the use of AI applications increases, there has been growing criticism of the rapidly produced, low-quality content. AI technology is new, and the best practices for its use are not widely known, so content generated without proper understanding tends to be of lower quality compared to that created by experts.
However, cases like Coca-Cola's advertisement last year demonstrate that AI generators, when used effectively, can facilitate the creation of creative and impressive content. As content creators and consumers develop a more positive view of AI generators, the number of AI-generated content pieces has been increasing significantly each year.
Future of AI sound effect generators
Currently, AI sound effect generators create sound effects based on text inputs. However, in the future, generators with higher input flexibility will emerge, capable of creating sound effects based on user voices or automatically generating suitable sound effects for video inputs. Experts predict that AI-generated sound effects will be widely applied beyond traditional mobile and PC environments to VR content as well. In more immersive VR environments, where there is greater interaction between users and content, AI sound effect generators will automatically add life to what you see and touch.
