Definitions

  • the invention relates to a method in the preamble of Claim 1 type described for multi-channel Sound reproduction in which the sound signals of a sound event are source-oriented and the mapping of the Allow original sound sources between recording and Playback also recorded, transmitted and multichannel may be registered for the purpose of changing this Signals before the final amplification and radiation via a Speaker arrangement with at least three front and two Surround speakers and a suitable one Device which in the preamble of claim 4 closer is defined.
  • Such systems and associated display devices are in ITU-R (formerly CCIR) recommendation BS.775 and in SMPTE standard PR 173 (1992) for a 3 / 2- or 3 / 4- or 3/2/1 system described.
  • Sound signal reproduction so perfected shows an improvement the playback quality with regard to the image of now three (or more) front information and regarding the Spatial information within a slightly enlarged listening zone.
  • a surround processor is also known (WO 91 19407 A), which derives further directional and spatial information-bearing partial signals from two-channel signals by summation, which are fed to further loudspeakers in order to emit radiation via three front and two surround channels achieve. It is an imitation that is supposed to produce a similar sound field as a result and to convey the subjective impression, ie the illusion, of how it can be generated with several discrete multichannel signals.
  • the aim here is to derive preferably further direct signals or approximately both direct signals and spatial signals, as can otherwise only be obtained from an original sound field with appropriate effort and appropriate recording technology under appropriate conditions.
  • the impersonators can be different for physical reasons just approximate an optimal discrete burst of signals and never due to signal distortions to be equivalent; they are real only as makeshift solutions and are generally considered to be processors for pseudo surround Watched playback.
  • the object of the invention is therefore to enable the defined listening zone for transmitted and recorded two-channel and multi-channel stereo signals to be enlarged for the space-independent reproduction of the spatial information while at the same time maintaining the specified directional information of the individual audio signal sources.
  • the loudspeakers should be able to receive favorable positions within the location distribution possibilities given by the space limits. In particular, this is intended to increase the usable proportion of the total room size for acoustic / visual performances. This also applies to larger rooms. It should be taken into account here that by converting available program materials with less than 5 channels, pseudo-multi-channel playback relationships are to be created in connection with known methods.
  • a device specially designed to carry out this procedure is suitable, is in the characterizing part of the claim 4 described.
  • the main effect of the invention is that shown in FIG. 1 Enlargement of the stereo listening zone while maintaining the complex auditory impression that can be achieved with the previous Two-channel stereo on a single reference point reduced by a point in the middle of the listening zone is indicated and in the standardized multi-channel sound arrangement (3/2 arrangement) only a small enlargement of the Listening zone allows by an inner white trapeze is designated.
  • the inner hatched trapezoid shows the Enlargement of the listening zone with appropriate localization of the Sound sources when applying the invention.
  • With the outside hatched hexagon is the possibility of further Enlargement of the listening zone by means of an additional derivative Playback channels shown schematically.
  • the inputs of the input stages (1-n) are with the outputs a multi-channel receiver or other one or multi-channel program sources connected.
  • the outputs of this Input stages are with the inputs of the input matrix EM connected. This distributes the existing input signals over the connections to the functional units FD, so that each FD receives n-1 of the available input signals.
  • the (n-1) outputs of each FD are connected to the inputs of a summing stage SE connected. Via a direct connection between the input matrix EM and each summing stage SE each arrive an unprocessed input signal in each summing stage, so that in each SE a sum signal from the n input signals can be formed.
  • the outputs of the summing stages SE - those on the output side Possibility of controllable level control included - are connected to the output matrix AM so that they are connected to the existing connected playback channels, d. H. With are connected to the inputs of the power amplifiers and via the output matrix is assigned to the corresponding playback channels become.
  • the outputs of the input stages E are included connected to the inputs of the conversion matrix KM and their Outputs with the corresponding inputs of the input matrix EM.
  • a filter unit FE-1 can be switched.
  • a filter unit FE-1 via a low-pass circuit from the existing input signals, preferably the three front signals, the low-frequency signal components filtered out, summed and assigned its own bass channel.
  • locations of the speakers and the desired listening zone is one for this special device Assign input unit EA. This enables the entry the locations of the speakers, their parameters, the existing ones Room conditions and the desired listener positions, the further the possibility of correcting and adjusting the conditions between direct information and desired room information (R / D) depending on the program material.
  • This input arrangement EA is in control with the individual Assemblies of the entire device connected and controls the variably adjustable parameters of the individual modules. It calculates parameters independently on the basis of the entered room and location parameters and assigns them to the corresponding assemblies.
  • the signal flow for a 5-channel program can be explained as follows:
  • the signals pass from the source (transmission channel, multi-channel recording, etc.) to the input stages E of this special device. They are distributed to the existing functional units FD by means of the input matrix in such a way that four of these 5 available input signals are assigned to each FD, so that one signal in each FD is not subjected to a parameter correction. (In the first FD, the first signal is switched unprocessed to the subsequent summing stage SE, in the second FD the second, etc.).
  • the four are related Level, duration and phase treated differently Signals and the once untreated signal again summed up and corrected together in level.
  • these sum signals are the existing ones Playback channels and the speakers connected to them with their performance levels according to their function definition (Front speaker surround speakers).
  • the functional units can FD can be expanded to include a parameter change allow for all input channels, so that for each playback channel a sum of all existing and treated input signals arises (Fig. 6)
  • a filter device FE-1 is connected downstream of the input stages, so are the low frequency parts of each unprocessed source signals filtered out, summed in the SE and assigned a separate bass channel that has a Level correction unit a special woofer supplied with the appropriate power unit.
  • the deviations from a standard list are due to the Entry of the location parameters in the input unit can be corrected.
  • additional parameters such as speaker data, Listening zone or listener positions etc. can both Volume ratios corrected as well as listening conditions outside of an optimal listening position, especially in the preferred area (preferred listener position) of the user, optimized become.
  • the ratio between direct component and surround component can also depending on the program material by entering appropriate correction values in the existing input unit changed, saved and assigned to the current program be retrieved again.
