PARAMETRIC STEREO UPMIX APPARATUS, A PARAMETRIC STEREO DECODER, A PARAMETRIC STEREO DOWNMIX APPARATUS, A PARAMETRIC STEREO ENCODER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18525910 titled 'PARAMETRIC STEREO UPMIX APPARATUS, A PARAMETRIC STEREO DECODER, A PARAMETRIC STEREO DOWNMIX APPARATUS, A PARAMETRIC STEREO ENCODER
Simplified Explanation
The parametric stereo upmix method described in the abstract involves generating left and right signals from a mono downmix signal using spatial parameters. Here is a simplified explanation of the patent application:
- Prediction of a difference signal between the left and right signals based on the mono downmix signal scaled with a prediction coefficient derived from spatial parameters.
- Derivation of the left and right signals based on the sum and difference of the mono downmix signal and the predicted difference signal.
Potential Applications
The technology could be applied in audio processing software, virtual reality systems, and surround sound systems.
Problems Solved
This technology solves the problem of converting mono audio signals into stereo signals while maintaining spatial parameters and enhancing the listening experience.
Benefits

Original Abstract Submitted
A parametric stereo upmix method for generating a left signal and a right signal from a mono downmix signal based on spatial parameters includes predicting a difference signal comprising a difference between the left signal and the right signal based on the mono downmix signal scaled with a prediction coefficient. The prediction coefficient is derived from the spatial parameters. The method further includes deriving the left signal and the right signal based on a sum and a difference of the mono downmix signal and said difference signal.
