Is there any 3D surround music?

Yes.

3D surround is a two-channel stereo signal processing that sounds from all directions. This system only uses two ordinary speakers and can have the shocking effect of a concert hall. It costs nothing, so it's very attractive.

3D surround positioning -

1. The sound changes from the sound source (including reflections from walls and floors) to the listener's ears can be simulated through head-related transfer functions and reverberation .

2. Some 3D technologies also convert head recordings into stereo recordings. MorrowSoundTrue3D converts binaural, stereo, 5.1 and other formats into 8.1 single-zone and multi-zone 3D sound effects in real time.

3. 3D audio technology is also used in music and video game-style music video art. The Audioscape research project provides musicians with a real-time 3D audiovisual content creation and rendering environment suitable for live performance applications.

Extended information:

The 3D sound effects and stereo sound of headphones are mainly different in terms of working principle, application scope and development process.

1. Differences in working principles:

The 3D sound effect of headphones uses speakers to imitate sounds that seem to exist but are fictitious.

Stereo sound in headphones refers to the simultaneous sound from multiple sound sources.

2. Differences in application scope:

The applications of 3D sound effects of headphones include: the direction of game sound effects, and bringing a sense of presence to music lovers.

Stereo applications of headphones include: the all-round sense of space brought by cinema audio, and Dolby stereo technology.

3. Differences in the development process:

The 3D sound effects of headphones originally came from a new PCI specification Monster Sound sound card boldly launched by Diˉamond Multimedia.

Stereo sound in headphones was invented in 1931. The inventor is British electrical engineer Alan Blumlein (1903~1942)
