    Sound limiter-recorder equipment with post-processing functions of
    audio and sound enhancement.
    SECTOR OF THE TECHNIQUE
    10
    The present invention is part of the field of sound control and processing in leisure facilities.
    BACKGROUND OF THE INVENTION
    European Directive 2002/49 / CE - Evaluation and management of environmental noise, transposed to Spanish legislation by Law 27/2003 of November 17, on Noise, defines the
    15 ambient noise as the unwanted or harmful exterior sound generated by human activities. According to the WHO (World Health Organization) exposure to noise affects children's cognitive development, can cause psychosomatic diseases and hearing impairment.
    20 The generation of noise is a process inherent to human economic activities and within these, it is of special importance that is generated as the basis of the activity itself, as is the case with leisure activities with music.
    This type of activity generates benefits for producers, but causes damage and
    25 damages to many other actors who are not beneficiaries of the activity. This damage must be stopped by the administrations in order to achieve a healthy and noise-free environment that does not affect the health of those not benefited from economic activity.
    30 In order to avoid this type of damage caused by leisure activities, national, provincial and local regulations sanction the transmission of sound outside of dedicated sound venues, such as discos or concert halls, that exceed a level of sound pressure.
    35 To avoid these sanctions and as part of the same regulations, equipment is required
    of limitation that act on the entire sound emission chain, ensuring that the maximum levels are not exceeded.
    At the same time, to adapt the loudness of the emitting equipment to the 5 characteristics of each premises, it is necessary to install sound post-processing equipment, such as equalizers, signal processors, filters, or crossover to mention some of the most common types.
    These two factors define complementary and complex needs since the installation of equipment in the sound chain after the limitation system can cause errors, emission situations over the maximum levels and, consequently, penalties.
    This type of installation adds complexity to the sound chain and hinders its certification in the competent administration. In addition to this problem, the number of redundant elements of an installation increases, increasing electrical consumption, the propensity for errors, high repair times and inconvenience for users such as noise and interference in the acoustic signal. These problems are aggravated if elements from different manufacturers or qualities are used.

    EXPLANATION OF THE INVENTION
    Therefore, the present invention has the objective of including and integrating 25 different audio processing systems in the sound limitation system. This way you can eliminate redundancies and ensure, in a certifiable way, that the entire sound chain complies with the regulations applicable to the installation where said equipment is installed.
    30 These audio processing systems can have interfaces that the end user can manage, as well as be managed automatically by the software included in the equipment, in order to improve the loudness or to adapt precisely to current regulations.
    To facilitate the understanding of the invention presented here, the following figure is detailed:

    Below is a list of the elements present in the invention:
    • Sound inputs (1). Sound inputs that will be processed and controlled. These can be multichannel, analog or digital.
    • Preprocessing stage (2). Systems whose most efficient processing is done before the control system. For example, and not exclusively, equalizers, amplifiers, signal conditioners and filters.
    • Measurement and control system (3). System responsible for measuring, limiting and controlling audio signals to accommodate regulations.
    • Post-processing stage (4). Audio post-processing systems such as crossover, splitters or the like whose functions do not alter the sound levels measured in the previous stage or whose function is known and predictable by the control system.
    • Sound outputs (5). Outputs where the processed and limited sound is sent to the amplification stage. These can be digital, analog or multichannel.
    25
    PREFERRED EMBODIMENT OF THE INVENTION
    The present invention can be made by manufacturing a device that includes, in the sound chain, hardware or software that perform the desired functions, as detailed in Figure 1: Sound chain design.
    30 This device could be implemented by creating a printed circuit where the components mentioned in the description are grouped together or by using a commercial prototyping board equipped with sound inputs (1), a DSP for audio pre-processing functions (2), a CPU or microcontroller with memory that performs the function of control and registration (3), a second DSP that performs the functions of audio post-processing (4)
    35 and sound outputs (5).
    The final realization of each component can be manufactured using hardware, software or combination of both.
