There is a person who makes sounds. I'm curious if this type of sound is considered a 3d sound. What defines a sound as 3d? When was the first 3d sound made in music? Has it always been around?

    Are you asking about 3D sound effect, and if so, what is your particular question ? – Edwin van Mierlo Nov 5 '18 at 7:43
  • There is no such thing as 3D sound. Humans have two ears, allowing us to only perceive sound (brain) as a combination of two point-sources of monophonic data (ears). We perceive sound as "stereo" although it can be recorded and processed in many more ways than this - mono, coincident stereo, spaced (time-delay) stereo, multi-mic, ambisonic. The term "3D" sound is simply a marketing term. If you are referring to "Virtual Reality" sound, research "Ambisonics". – Mark Nov 11 '18 at 11:40
  • @mark - Agreed, but: There is no such thing as 3D sound. Well, technically all sound is 3D, since it fills a volume of space (-: – Jim Mack Nov 14 '18 at 19:07
  • @JimMack "filling a volume of space" isn't justification in any way for defining 'all sound as 3d'. With reference to a 3 dimensional space, all sound sources in that space have intensity, frequency, phase and position but are themselves can be derived from point-sources. There's really no point in giving credence to what is effectively a 'marketing' term simply to add to the confusion. – Mark Nov 16 '18 at 11:30
  • @Mark - Did your humor license expire? I guess you missed the part where I agreed with you. – Jim Mack Nov 16 '18 at 14:05
