Abstract: High frequency components of audio signals are reconstructed from the aspects of envelope and fine detail. The envelopes of the high frequency components are found through linear extrapolation of signals with frequencies lower than a cutoff frequency point. One method of reconstructing high frequency components is based on the linear extrapolation on the logarithm scale magnitudes of the transform coefficients of the audio signal in a frequency domain. The linear extrapolation is a linear approximation based on minimizing least squares of the logarithm scale magnitudes of the transform coefficients of the low frequency components. Another method is based on the linear extrapolation on the logarithm scale magnitudes of the envelope elements of the filterbank signals of the audio signal over a time segment. The linear extrapolation is a linear approximation based on minimizing least squares of the logarithm scale magnitudes of the envelope elements of the low frequency filterbank signals.

Abstract: An FIR-based apparatus performs fast convolution in the frequency domain for generating room reverberation. The impulse response of a room is segmented and transformed by FFT to form a plurality of segmented room frequency spectra. The input signal to the room is also segmented and transformed to form segmented input frequency spectra. Either overlap-and-add method or overlap-and-save method is applied in the apparatus to accomplish the fast convolution based on the multiplication of segmented input frequency spectrum and segmented room frequency spectrum. To further reduce the complexity of the convolution, a segmented room frequency spectrum is processed to remove high frequency components before being used in the fast convolution according to a perceptual criterion.
