Definitions
- the invention relates to signal systems and apparatus for the conversion of corresponding signals.
- the invention is explained with reference to various transducer systems and other practical examples.
- JP 11146499 A (Tatsuya & Masao, 1999 ) stays in the targeted Use of phase shift in the dependence on frequencies in the sense of the above quotation Dickreiters, scientifically limited, limited (" To provide a pseudo stereo circuit in simple configuration. "- Tatsuya & Masao, 1999 ), and, clearly delimited, does not constitute a specific technical implementation, characterized by the angle ⁇ , which includes the sound source and the main axis, as a central feature of the present invention.
- FIG. 5 provide an ideal pseudo-stereophonic signal based on the directional characteristics of a sphere, provided that the signals obtained are then of the prior art so-called stereo implementation described under "Equivalent Polar Pattern Combination Combinations of XY and MS Microphone Techniques" (US Pat. Diekreiter, 1987).
- the central characteristic here is the parameterization of the angle ⁇ , the sound source and the main axis, which is technically exactly realized, clearly distinguishable from the arrangement.
- FIG. 7 is the arbitrarily segmented uptake of sound events in a room de facto without restrictions or interference.
- The, binaural models exactly enabling function and construction principle is derived from FIG. 6 off.
- the stereo signal derived from the application example, III. Yields a completely compatible one, as long as the sound source does not come to rest on the main axis of the sound transducer.
- the technically implemented targeted parameterization of the angle ⁇ , the sound source and main axis include basically using the principles of action systematic so-called polarity reversal and Pegelum differences in transit times basically possible to achieve technical arrangements which are able to supply all the signal combinations corresponding to the technical state in the sense of Dickreiter's explanations (Dickreiter, 1987) or even expand this canon as desired!
- the invention also provides new technical solutions for highly efficient processor architectures.
