AI Technical Summary

Problems solved by technology

The reason for this is that conventional loudness compression and maximization techniques are not conducive to comfortable background music
Furthermore, the desired dispersion of sound covering a venue cannot be achieved by using very many loudspeakers placed too close to each other, since these loudspeakers add up in their sound and thus create a sound concentration that usually also includes a difference in travel time and a phase shift, both of which both adversely affect sound perception

Embodiment Construction

[0048] Figure 1a A device according to the invention is shown, which is provided with the reference numeral 100 and is in the form of a portable box-shaped container.

[0049] The device 100 has an effect unit which is integrated into the device 100 and which is present as an audio compressor 10 in the embodiment shown in FIG. 1 .

[0050] as from Figure 1a It can also be seen that the rear side of the device 100 has audio inputs 11 , 12 and audio outputs 13 , 14 for audio signals. Audio inputs 11 , 12 and audio outputs 13 , 14 are connected to audio compressor 10 via signal lines 11 a , 12 a , 13 a , 14 a extending within the device.

[0051] exist Figure 1a In the embodiment of the device shown, the audio inputs 11 , 12 are two asymmetrical RCA jacks forming the audio inputs for the left and right audio channels. The audio outputs 13 , 14 are corresponding asymmetrical audio outputs and are present as asymmetrical RCA jacks.

[0052] In addition, if Figure 1a As furthe...

Abstract

The invention relates to an apparatus (100) having an input (11, 12, 15, 16) and an output (13, 14, 17, 18) and having an effect device with volume-regulated audio signals from an audio file or audio source, wherein the audio signals have input levels at an input of the effect device and output levels at an output of the effect device. In order to achieve background sound which is as optimal as possible, the invention proposes that each input level is assigned to a preset output level irrespective of the content of the audio file or audio source, wherein the input level is regulated to the output level.

Description

technical field [0001] The invention relates to a device according to the preamble of claim 1 . Background technique [0002] Such a device is known from US 4 249 042A. [0003] In this previously known device, an audio compressor is used as an effector to make the audio signal sound as loud as possible by maximizing the loudness parallel to the audio signal level. The aim in US 4 249 042A is to make an already loudest produced music track sound even louder in a radio station. For this purpose, the peak levels of the audio signal are cut (so-called transients) so that softer parts of the sound appear louder. In order to reduce audible distortions, a low-pass filter is provided at 17 kHz in US 4249 042A, which means that the audio signal in the frequency range between 17 kHz and 20 kHz is somewhat cut off. To slightly compensate for this loss, the band at 15kHz is boosted by 4dB. Use a three-band compressor for this. If an energy spike occurs in the middle band, the comp...
