Sound effect

sound effectsound effectseffects
3D audio effects are a group of sound effects that manipulate the sound produced by stereo speakers, surround-sound speakers, speaker-arrays, or headphones.
The modern systems also frequently utilize positional audio, often with hardware acceleration, and real-time audio post-processing, which can also be tied to the 3D graphics development.

AMD TrueAudio

TrueAudio is the name given to AMD's ASIC intended to serve as dedicated co-processor for the calculations of computationally expensive advanced audio effects, like e.g. convolution reverberation effects and 3D audio effects.

Besides providing the essential service of passing audio data to the sound card, DirectSound provides other essential capabilities such as recording and mixing sound, adding effects to sound (e.g., reverb, echo, or flange), using hardware accelerated buffers in Windows 95 through XP, and positioning sounds in 3D space.

The Death of Bunny Munro

Nick Cave's novel The Death of Bunny Munro was recorded in audiobook format using 3D audio.
The novel was also released as an audiobook, using a 3D audio effect produced and sound directed by British artists Iain Forsyth and Jane Pollard, with a soundtrack by Nick Cave and Warren Ellis and in a number of Ebook formats including an iPhone application that synchronised the audiobook with the text, and included exclusive videos of Cave reading.

Imogen Heap

The song "Propeller Seeds" by English artist Imogen Heap was recorded using 3D audio.

Surround sound

It allows trickery of the brain using the ears and auditory nerves, pretending to place different sounds in different 3-D locations upon hearing the sounds, even though the sounds may just be produced from just 2 speakers (dissimilar to surround sound).



Q SoundQsoundQ3D
QSound is the original name for a positional three-dimensional (3D) sound processing algorithm from QSound Labs that creates 3D audio effects from multiple monophonic sources and sums the outputs to two channels for presentation over regular stereo speakers.

Oculus Rift

The device also features rotational and positional tracking, and integrated headphones that provide a 3D audio effect.


Sensaura, a division of Creative Technology, is a company that provides 3D audio effect technology for the interactive entertainment industry.

In some cases, processing such as equalization, dynamic range compression or stereo processing may be applied to a recording to create audio that is significantly different from the original but may be perceived as more agreeable to a listener.

Along the bottom edges of the side, located near the user's ears, are a pair of small, red 3D audio speakers.

QSound Labs

The company is best known as a pioneer of 3D audio effects, beginning with speaker-targeted positional 3D technology applied to arcade video games and professional music and film soundtrack production.

During the 1990s, CRL spawned another technology: Sensaura 3D positional audio.


It provides access to features such as 3D positional audio and MIDI playback.

Environmental Audio Extensions

EAX is a library of extensions to Microsoft's DirectSound3D, itself an extension to DirectSound introduced with DirectX 3 in 1996 with the intention to standardize 3D audio for Microsoft Windows, adding environmental audio presets to DS3D's audio positioning.

Advanced Multimedia Supplements

JSR-234 application programming interfaceJSR 234
Practically speaking, it is an extension to JSR 135 Mobile Media API providing new features, such as positional 3D audio processing, audio and video effects processing, better controls for digital camera, and better support for analog radio tuner including Radio Data System.


SoundRenderer is a spatialized audio rendering plugin for Maya to simulate 3D-positional audio.

Dungeon Master (video game)

A slightly updated Amiga version was released the following year, which was the first video game to use 3D sound effects.

Eurofighter Typhoon

The system is compatible with ANR, a 3-D audio threats system and 3-D communications; these are available as customer options.

Java 3D

Additionally, Java 3D offers extensive spatialized sound support.
