Definitions

  • the invention relates to a method for multi-channel sound processing in a multi-channel sound system according to the preamble of claim 1.
  • the front signals Lo and Ro, the center signal Co and the surround signals L RO and R RO are derived from stereo signals, ie from the input signals L and R.
  • the respective other signals are subtracted from the signals L, R, L + R and LR with a weighting.
  • frequency-dependent weighting factors are derived in addition to the level ratio calculations.
  • the center signal C is varied only in the level, whereas the two surround signals L and R RO RO in two frequency bands and phase inverted derived.
  • the coefficients a 1 ... A 8 of these weighted summations are derived from level measurements.
  • two control signals from the level difference of a left and right channel D LR and level difference of a sum and difference signal Des are calculated.
  • the two front signals L out and R out are thereby from the two input signals L and R and the subtraction of a weighted sum signal (L + R) and of a weighted difference signal (LR) obtained.
  • the center signal C results from the sum (L + R) and the subtraction of the weighted input signals L and R.
  • the surround signal S is made up of the sum (LR) and the subtraction of the weighted input signals L and R.
  • the weighting coefficients g l , g r , g c and g s are obtained from a level matching of the signals L and R and L + R and LR in a recursive structure.
  • This time-variant multi-channel control ensures a spatial displacement of the signal, if then again a stereo encoding is made.
  • Much more decisive for a spatial resolution improvement of stereo signals is an extraction of directional signal components and their weighting by static or frequency-dependent weighting. Therefore, the document WO 2010/015275 A1 represents a significant advance of the method of the type mentioned, since here the decomposition of stereo signals in spatial proportions takes place in order to assess these with different level controls. Thereafter, the valued spatial signals are reassembled into a stereo signal. Due to the weighting of the spatial signal components, the stereo signal experiences an improvement of the spatial reproduction.
  • US2012 / 0263306 A1 discloses a four-channel stereophonic device. It is therefore an object of the invention to further develop a method of the type mentioned above, that on the basis of an extraction of directional signal components, a further improvement of the spatial reproduction of the input signals L and R is achieved. This object is achieved with the features of claim 1.
  • the derivation of the surround signals from the difference LR has proven to be another important step for improved stereo and spatial expansion.
  • a space signal R is formed into a center signal.
  • the space signal is formed from the difference between the signals L and R (R L ) and / or the difference between the signals R and L (R R ).
  • the inventive method a spatial and Stereo extension of a stereo signal achieved by an extension of the stereo decomposition.
  • the advantage here is a frequency-dependent weighting of the surround signals.
  • a frequency-dependent weighting of the signals S L and S R takes place .
  • the frequency-dependent weighting is preferably carried out by means of a height-helving filter.
  • the signals L and R are expediently added to the signals L P and R P.
  • the invention also provides software residing on a signal processor, i. is imported to the signal processor.
  • the software contains an algorithm which is processed by the signal processor, the algorithm detecting the method.
  • the method begins with the fact that in the context of decoding the input signals L and R, which are present as stereo signals, are divided into three signal components, wherein the signals L and R can be retained.
  • the signal components are the center signal C, the spatial signal R and the surround signals S L and S R.
  • the center signal C is single-channel, ie it contains only the channel C, whereas the space signal R and the surround signal S are two-channel, ie they contain the signals R L and R R and S L and S R.
  • the surround and space signals S L , S R and R L and R R contain the direction and spatial information of the stereo signals L and R.
  • the process section A is followed by the process section B, in which the processing of the channels C, R L , R R , S L and S R takes place.
  • these signals are provided by first level control 1, 2 with a level weighting, which manifests itself in the factor 1.5.
  • the further level controls 3, 4 provide a further variable level weighting, which weights the sound characteristics of the decoded signals to L, R.
  • the filters 5, 6 have a minimum phase shift in the frequency range of preferably 2 kHz, so that extinction effects are minimized in the taking place in process section C encoding, at the same time the actual gain effect is emphasized with a height helving frequency response of, for example, 3 dB, preferably 2KHZ.
  • the surround signals S L , S R are supplied to the level selectors 7, 8 which weight the sound characteristics of the decoded signals to S L , S R.
  • the encoded weighted signals are found L P , R P a post-processing by stereo equalizer 9, 10.
  • a special non-linear characteristic NL is used. This non-linear characteristic maps an input amplitude x to an output amplitude y.
  • the signals L P , R P undergo further post-processing in the method section D such that the level adjusters 11, 12 determine the degree of overtone mixing to the direct signal. Further processing is finally carried out by the level control 13, 14, which make the overall level of the process result adjustable.
  • the present invention is not limited in its execution to the embodiment given above. Rather, a number of variants is conceivable, which make use of the solution shown in other types.
  • ie compressors / limiters are used to further enrich the sound image.
