Cartesian Coordinate Systems¶
1. Mathematical System: (Navigational)¶
- right-handed system, y to the front, x to the right, z to the top
adapted from: Bronstein, Semendjajew, Musiol, Mühlig: Taschenbuch der Mathematik
2. Shifted Mathematical System: (Acoustical)¶
- right-handed system, x to the front, y to the left, z to the top
- Blauert System in cart. coordinates,
3. OpenGL, OpenAL System¶
- right-handend system, x-axis to the right, y to the top, z to the back
Spherical Coordinate Systems¶
1. Mathematical System:¶
- azimuth: zero to the right hand-side, counter-clockwise increase
- elevation: angle starts from the positive z-axis
adapted from: Bronstein, Semendjajew, Musiol, Mühlig: Taschenbuch der Mathematik
2. Navigational system:¶
- azimuth: 0 degree in the front, clockwise increase
- elevation: angle is defined between -90.0 (below) and 90.0 degree (above), 0 degree means no elevation

3. Blauert / Gerzon System:¶
- azimuth: 0 degree in the front, counter-clockwise increase
- elevation: as in Navigational system
adapted from: Blauert, J. (1997). Spatial hearing: the psychophysics of human sound localization. MIT Press, Cambridge, Mass., rev. edition. p. 41
