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
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.

DirectSound

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.
