Asynchronous sound is a type of audio that doesn’t require your computer’s main processor to process the sound. Instead, this type of sound is processed by a dedicated device called an audio card.

Asynchronous sound is similar to USB audio, except that it only uses one device for both sending and receiving the audio.

An asynchronous speaker uses an independent digital-to-analog converter (DAC) to convert digital signals into analog signals and vice versa. An asynchronous DAC can be used as an input for a PC or as an output for an amplifier or another device.


What Is Asynchronous Sound

What Is Asynchronous Sound?

Asynchronous sound is a term used to describe an audio file that has been recorded or digitized separately from the video.

In other words, it’s audio that was recorded at a different time – often in a different location – from the main video stream.

The most common use case for asynchronous sound is when you have a single camera recording video and audio. The camera itself only records one stream of data at a time – either video or audio.

By using an external microphone or recorder, you can record your own separate track of audio to customize your videos with music, narration or other sounds.

Asynchronous sound is also used for multi-camera shoots where you are using multiple cameras (and therefore multiple microphones) as well as for multi-track recordings like 5.1 surround sound setups.



Asynchronous speakers are not always necessary since most computers now have built-in speakers and some devices have built-in speakers as well—like laptops. But if you want better sound quality than what comes with your computer or mobile device, consider adding an external speaker system with its own DAC.

Asynchronous Sound Characteristics

 Asynchronous sound characteristics are the result of a speaker’s delay between the time it takes for the sound to travel through the air and reach your ears.

This is why speakers that have a wider dispersion pattern have better spatial characteristics, as they’ll have more space for sound to move around in. On the other hand, speakers with narrow dispersion patterns will have less depth perception.

The biggest single factor in how a speaker sounds is its power handling capability — how much power it can handle before clipping occurs. Higher power handling means better bass response and less distortion at higher volume levels.

The second most important aspect of a speaker’s sound quality is its frequency response, which affects low-end performance but not so much high-end performance. Frequency response refers to how well each frequency range from human hearing (20Hz-20kHz) is reproduced by an audio system or device (in other words, how flat it sounds).

Asynchronous Sound Effects

Asynchronous sound effects are a great way to add some life to your game, especially if you’re working with a small budget.

The idea is that instead of playing sounds as they happen, you play them at a later time. This allows for a more natural feeling of movement and gives the player time to react while they wait for the sound effect to play.

For example, if a character walks across the screen and then shoots his gun, it might be interesting if he did so without any music or sound effects at all. But if he walks across the screen and then shoots his gun, it would be much more immersive if he did so with some background music or other audio cues to help build up suspense.

This could also be useful for creating atmosphere with sounds that aren’t tied directly to gameplay events (like footsteps or gunshots). After all, if you’re worried about how long your player will take between actions, then it’s probably not worth going overboard with long gaps between sound effects anyway.

When To Use Asynchronous Sound

 Asynchronous sound is a way to send audio signals over the internet. This can be used in any application that requires audio, but it’s most often used for games and music applications.

Asynchronous sound allows audio to flow over the internet without relying on the traditional method of using a server on a local network. Asynchronous sound does not require an Internet connection at all times, which allows you to use your computers as servers for other users on your network.

The benefit of asynchronous audio is that it allows you to have better control over where your audio goes and how fast it moves through the network. This may be useful if you want to send customized sounds from one location in your game or application, or if you need to make sure that certain sounds play at specific times during gameplay.

Asynchronous Sound In Film

 The term asynchronous sound refers to the audio track of a film that was recorded separately from the film itself. The standard process for creating such a recording is to record dialogue, music, and sound effects before shooting a scene.

The director then edits together these elements in postproduction and synchronizes them with the actual footage of the scene. This process is known as dubbing or synching, depending on whether you’re referring to dialogue or sound effects.

The benefits of this method are obvious: It allows filmmakers to use sounds that would be impractical or impossible for actors to perform in real life — for example, ambient noises coming from rooms other than the one they’re filming in, or a character’s voice echoing across an empty room.

The downside is that it can create an uneven tone when compared with other methods because these sound effects have not been captured during actual filming.

Asynchronous Sound Examples

 In the following examples, we will look at how to use the async() function and its parameters.

Asynchronous sound example:

In this example, we will play a sound after 3 seconds with an event handler on the load event.

We will have a button that when pressed plays a sound and then another that also plays a sound after 3 seconds.

First of all, we add the async function and its first parameter which are the location of where we want to place our code at, which in this case is page_start(). Then we add our callback function which is called on load and whenever it is called, it runs through all of its arguments and then calls this function with undefined as its value so that it can play our sound.

Now let’s look at adding a second button that has an event handler on the click event and when clicked it will also play a sound but after 5 seconds instead of 3 seconds!

Asynchronous Sound In The 39 Steps Film

 The 39 Steps is one of Alfred Hitchcock’s best known films. It was released in 1935 and features a thrilling story, memorable characters and some of Alfred Hitchcock’s most famous scenes.

One of the most popular scenes in the film is when Robert Donat plays Richard Hannay, who has been framed for murder after being kidnapped by terrorists. After escaping from his captors, Richard walks through a London fog and comes across a group of boys playing football. As he watches them play, a woman rushes across the field to retrieve her lost purse.

As you can see from this clip from The 39 Steps, there are several instances where asynchronous sound effects are used during dramatic scenes. In fact, there are so many instances that I have decided to break them down into categories so that they can be more easily understood by viewers who may not be familiar with sound editing terminology or techniques.

Synchronous And Asynchronous Sound In Mother! Film

 The film’s sound design is a key component in the film’s atmosphere, and it is essential to the plot. The sound design is synchronous and asynchronous in nature.

Synchronous sound design occurs when the sounds are in time with one another, while asynchronous design occurs when they are not.


The synchronization of sound in this film can be seen through its use of ambient noises and music, as well as its use of dialogue. The ambient noises are used to set the tone for each scene and create an atmosphere for the scene. The music also has a specific purpose for each scene, which helps set up the mood for that particular scene.

Sound Design And Dialogue In Mother! Film

One way in which Mother! uses sound to enhance its atmosphere is through its use of dialogue. There are several instances throughout the film where dialogue is used to enhance a scene or convey information about what is happening on screen:

– When Dr. Sean Harris is talking to his wife about making a mistake by having an abortion, there is no clear voiceover from him but instead ambient noise from outside the room can be heard while they are talking (this helps create tension between them)

Industrial Soundscapes In Eraserhead Film – Asynchronous Sound Effects

 Eraserhead is a horror film by David Lynch. The film stars Fred Ward, Mary Woronov and John Beck as the protagonist Henry Spencer.

The film was released in January of 1986 and has gained cult status since its release.

One of the most memorable aspects of Eraserhead is the sound design. The film uses a mixture of synths and analog synths to create an industrial soundscape.

The soundtrack for Eraserhead is quite unique in its use of asynchronous sound effects (ASF) instead of standard synchronous sound effects (SSF). ASF occurs when there are delays between the recorded audio and what is heard on screen or in other media formats such as TV or movies.

In this video I will show you how ASF was used in Eraserhead by David Lynch and how it was used to create an eerie industrial soundscape that gives a more realistic feel to the film’s setting.

What Is Asynchronous Sound – Wrapping Up

 So, what is asynchronous sound? It’s the use of sound in a movie or video game where the audio is not synchronized with its video counterpart.

Asynchronous sound refers to the fact that there is no real-time synchronization between the two – the audio will be delayed by up to several seconds, making it difficult for the player to hear what’s happening around them.

This can be used to great effect when creating tension in a scene and making things feel more immersive. However, this also means that there will be times where you don’t know if an enemy has heard you or not until they attack you, for example.

There are many different ways you can use asynchronous sound in your next project – from using it as a way to create tension in a scene, through to just using it for atmosphere – so let’s take a look at some examples!
