Abstract
System and method for enhancing audio reproduced by an audio reproduction device is described. A plurality of convolution coefficients are generated for a predefined space. A digital audio signal is modified based on the generated convolved digital audio signal to generate a convolved digital audio signal. The convolved digital audio signal is converted to a convolved analog audio signal. The convolved analog audio signal is fed to the audio reproduction device.
Claims20
A method for enhancing audio reproduced by an audio reproduction device, including:
- generating a plurality of convolution coefficients for a predefined space, based on both a direct and reflected sound waves from the predefined space, for at least two channels;
- modifying at least two channels of digital audio signal received for reproduction based on the generated plurality of convolution coefficients for the predefined space, to generate a convolved digital audio signal for the at least two channels of digital audio signal with effect of the predefined space;
- adding correction to the generated convolved digital audio signal with mid side modification based on a middle-side filter to generate a modified convolved digital audio signal;
- generating at least two channels of convolved analog audio signal with effect of the predefined space, based on the modified convolved digital audio signal with effect of the predefined space, for the at least two channels of digital audio signal;
- and feeding the at least two channels of convolved analog audio signal with effect of the predefined space to the audio reproduction device, for reproduction.
