Definitions

  • FIG. 2 is a functional schematic block diagram of an audio signal process or processing method embodying aspects of the present invention.
  • FIG. 3 is a functional schematic block diagram showing the Time and
  • the normalized frequency spectrum for a current block may be compared to the normalized spectrum from the next previous block to obtain a measure of their difference.
  • a single difference measure may be calculated by summing the absolute value of the difference in the dB spectral values of the current and next previous spectrums. Such difference measure may then be compared to a threshold. If the difference measure is greater than the threshold, an event boundary is indicated between the current and previous block, otherwise no event boundary is indicated between the current and previous block.
  • a suitable value for this threshold has been found to be 2500 (in units of dB). Thus, event boundaries may be determined within an accuracy of about half a block.
  • the cross-correlation may be performed using standard FFT based techniques to reduce execution time. Since both S 1 and S 2 are finite in length, the non-zero component of R 1 2 has a length of Ni +N 2 -1. The lag / corresponding to the maximum element in R 12 represents the delay of S 2 relative to -S 1 .
  • both CaIc Delays 301 and Delays 305-1 through 305-P may operate in the frequency domain, in which case Delays 305-1 through 305-P perform phase adjustments to bands or subbands, rather than delays in the time domain.
  • signals 306- 1 through 306-P are already in the frequency domain, negating the need for a subsequent Filterbank 401 (FIG. 4, as described below).
  • a useful value for ⁇ b) has been found to be 0.5 except for bands below approximately 200 Hz. Below this frequency, ⁇ (b) tends toward a final value of 0 at band b—0 or DC. If the smoothed gains G 5 are initialized to 1.0, the value at DC stays equal to 1.0. That is, DC will never be gain adjusted and the gain of bands below 200 Hz will vary more slowly than bands in the rest of the spectrum. This may be useful in preventing audible modulations at lower frequencies. This is because at frequencies lower than 200 Hz, the wavelength of such frequencies approaches or exceeds the block size used by the filterbank, leading to inaccuracies in the filterbanks' ability to accurately discriminate these frequencies. This is a common and well- known phenomenon.
  • FIGS. 7a and 7b show the room or spatial locations of two sets of audio channels.
  • device or process 702 may assume a priori knowledge of the spatial locations of the content channels. Information regarding the number and spatial location of the additional intermediate channels may be assumed or may be passed to the device or process 702 from the decorrelating device or process 701 via path 703. This enables process or device 702 to combine the additional intermediate channels into, for example, the nearest two playback channels so that phantom image direction of these additional channels is maintained.
