1 Two ears - two loudspeakers? 11 The spatiality of recording. 12 Perception of phantom acoustic source. The reason for that loss in spatial impression is crosstalk between the ears. The signal of the left speaker does not arrive at the left ear alone. With a detour around the head, the wave fronts also reach the right side as well as the converse. That boosts Interaural Cross Correlation. 13 Two rooms in one recording. Of the Wave Field Synthesis. Next Chapter Sound and Room. The spatiality of recording.

Spatial Sonic Field

2 The spatial sonic field. 21 Space in Channels. As long as we are pursuing the goal of pleasant perception, this sort of procedure is satisfying. However, for reproducing the clarity of a voice in an excellent acoustic environment, the hum of a bee close to our nose, or to create the emotional impression of the spatial sonic field in one of the famous concert halls throughout the world, the perception of phantom sources is collapsing. 22 The mirror source model. As far as we would be able to determine, ...

Virtual acoustic source

http://www.syntheticwave.de/virtual%20acoustic%20source.htm

As described by Huygens principle. For a limited range of l is possible establishing the wave front according to Huygens principle electronically by a loudspeaker array. The radiation of each single loudspeaker becomes a delay until the wave front of the virtual sound source would hit concerning loudspeaker:. If the loudspeakers align in a plane, the acoustic curtain. Approach in the optical range within reach. The principle is shown by the wave field synthesis website. Next chapter: wave field synthesis.

Loudspeaker adaptation

http://www.syntheticwave.de/Speaker_Field_Adaption_for_WFS.htm

Loudspeaker adaptation at the resistance of air. Dynamic loudspeakers, mounted in compact boxes, pose a common problem: Its efficiency is pitiful. In one meter distance hardly more as one percent of the injected electric power is converted in sound energy. The problem isn't mainly caused by the efficiency of the driving system itself. The main problem consists in the lousy adaption of the diaphragm regarding the load resistance of the moved air. The efficiency of such guided system incomparably better as...

Initial Time Delay Gap ITDG

http://www.syntheticwave.de/ITDG.htm

Initial Time Delay Gap ( ITDG). The Initial Time Delay Gap describing the time difference between arrival of the direct wave and first strong reflection at the listener. Nearby sources are causing a long ITDG. In case of the source are far away, hardly run time differences arise:. The spatiality of recording. Two rooms in one record. 2 The spatial sonic field. The mirror source model. 3 Wave Field Synthesis. Near field and the acoustic curtain. Subtraction of playback room acoustics.

Phantom Sources

http://www.syntheticwave.de/Phantom-sources.htm

Phantom sources and spatial accuracy. Tonal accuracy is the best that can be hoped for in a traditional audio system; true spatial accuracy will never happen. Audio products should come bearing this disclaimer:. WARNING: IMAGE PRESENTED IS LESS THAN LIFELIKE. Let's search the problems in the principle of phantom source imaging and illuminate the facts:. That exalts the Interaural Cross-Correlation Coefficient. Something to the effect that some people doesn't receive an impression of spatiality from an pe...

Wave Field Synthesis

http://www.syntheticwave.de/Wavefieldsynthesis.htm

3 Wave Field Synthesis. Wave Field Synthesis, also known as WFS, label a spatial audio reproduction procedure. The principle no longer remains dependent on psycho-acoustic phantom sound source perception, like all conventional audio procedures. The soundfield is reconstructed physically. For this purpose, the synthesis emulates nature like wave fronts according to Huygens' principle. 321 Virtual acoustic sources. Cannot produce true spatial audio for this reason. One possibility for establishing such...
