The present invention provides for methods and systems for digitally processing an audio signal. Specifically, the present invention provides for a headliner speaker system that is configured to digitally process an audio signal in a manner such that studio-quality sound that can be reproduced.

The present invention provides for methods and systems for digitally processing an audio signal. In various embodiments, a method comprises receiving a profile comprising a plurality of filter equalizing coefficients, configuring a plurality of filters of a graphic equalizer with the plurality of filter equalizing coefficients from the profile, receiving a first signal for processing, adjusting the plurality of filters using a first gain, equalizing the first signal using the plurality of filters of the graphic equalizer, outputting the first signal, receiving a second signal for processing, adjusting the plurality of filters, previously configured with the filter equalizing coefficients from the profile, using a second gain, equalizing the second plurality of frequencies of the second signal with the plurality of filters of the graphic equalizer, and outputting the second signal.

The present invention(s) provides for methods and systems for digitally processing a ringtone. In various embodiments, a method comprises generating a profile comprising a plurality of filter equalizing coefficients, configuring a plurality of filters of a graphic equalizer using the plurality of filter equalizing coefficients from the profile, receiving a ringtone for processing, adjusting the plurality of filters using a first gain, equalizing the ringtone using the plurality of filters of the graphic equalizer, and outputting the equalized ringtone.

The present invention provides for methods and systems for digitally processing audio signals by adjusting the gain of a signal a first time, using a digital processing device located between a radio head unit and a speaker. The methods and systems may filter the adjusted signal with a first low shelf filter, compress the filtered signal with a first compressor, process the signal with a graphic equalizer, compress the processed signal with a second compressor and adjust the gain of the compressed signal a second time. The methods and systems may also filter the signal received from the first low shelf filter with a first high shelf filter prior to compressing the filtered signal with the first compressor. The signal may be filtered with a second low shelf filter prior to processing the signal with the graphic equalizer. Some embodiments filter the signal with a second high shelf filter after the signal is filtered with the second low shelf filter.

Anthocyanic colorant made of vegetable primary material and process for its production relate to food, cosmetic, pharmaceutical and textile industry and may be used in production of alcoholic and soft drinks, confectionery, products made of sour milk, in coloring of tablet capsules, dying of children's underwear, toys, etc. According to the invention, pelargonidin glycoside was added to the composition of the natural colorant that contained cyanidin glycosides, peonidin glycosides, organic substance and mineral salts. The components percentage shall be as follows, %: cyanidin glycoside 0.1-8.6; peonidin glycoside 0.08-6.45 pelargonidin glycoside 0.005-4.3; organic substance and mineral salts--the rest. Due to the fact that the colorant solution contains pelergonidin glycoside further to cyanidin and peonidin glycosides, the proposed colorant obtained expanded color spectrum. Combination of these three anthocyans in the proposed colorant provides for the most rich spectrum of red colors. At the same time, the ratio of pelargonidin glycoside:peonidine glycoside:cyanidin glycoside must be 1:1.5:2, respectively, and it will provide for production of a colorant with a number of valuable physical properties. Namely, the colorant retains red color when pH of the environment is not more than 7, it is thermostable, photostable and maintains its properties during 2 (two) years, besides, its relative optical density is the highest when it is subjected to the light with wavelength of 505-515 nm. According to the invention, process of the colorant production implies that pre-dried vegetable maize-pulp containing anthocyan is grinded, extracted by a mix of aqueous solutions of hydrochloric and citric acids in the field of ultrasonic vibration. Then the extracted coloring matter is filtered and concentrated in vacuum. The primary material is additionally prepared for extraction by infusion of grinded material in extracting agent during 6-8 hours at the temperature of 35-40.degree. C. Extraction may be performed in three steps. Processing for extraction of each lot shall be 30-40 minutes at the temperature of 35-40.degree. C. The process makes the production technology easier and provides for additional source of primary materials. 2 independent claims, 8 dependent claims, 5 tables.

The invention belongs to the liquid crystal display field, and provides a liquid crystal display device, comprising a liquid crystal panel and a backlight system. The backlight system comprises a plurality of CCFL lamp tube groups or a plurality of CCFL lamp tubes. Each CCFL group or each CCFL lamp tube sends spectrum curve having at least five main peaks with different spectrums. The main peaks of the five main peak with different spectrums are five spectrums with different colors. The five different colors include light of red, green and blue. The invention increases backlight spectral line width by increasing luminescent sources of other spectral line different from that of red, green and blue light, has backlight source with wide spectrum, thereby showing approximate real color of natural object, to make it comfortable to observe.
