Yandisa

Ibhekisa ekubeni ingaba isithethi siyalixhasa na igalelo leetshaneli ezininzi ngaxeshanye, nokuba kukho ujongano lwemveliso yezithethi ezijikelezileyo, nokuba inomsebenzi wegalelo le-USB, njl. njl. iikhrayitheriya zokulinganisa ulwandiso lokusebenza.Ujongano lwezithethi eziqhelekileyo zemultimedia ziquka ikakhulu ujongano lwe-analog kunye nojongano lwe-USB.Ezinye, ezinje ngojongano lwefiber optical kunye ne-innovative digital interfaces, aziqhelekanga kakhulu.

Isiphumo sesandi

I-hardware eqhelekileyo ye-3D iteknoloji yeziphumo zesandi ziquka i-SRS, i-APX, i-Spatializer 3D, i-Q-SOUND, i-Virtaul Dolby kunye ne-Ymersion.Nangona zineendlela ezahlukeneyo zokuphumeza, zonke zinokwenza abantu bazive imiphumo yesandi esinemigangatho emithathu.Ezithathu zokuqala zixhaphake kakhulu.Into abayisebenzisayo yithiyori ye-Stereo eyandisiweyo, eyongezelelweyo ukuqhubekekisa umqondiso wesandi ngokusebenzisa isekethe, ukuze umphulaphuli azive ukuba isalathiso somfanekiso wesandi sandiswe ngaphandle kwezithethi ezibini, ukuze kwandiswe umfanekiso wesandi kwaye wenze. abantu banengqiqo yendawo kunye ne-dimensionality-ntathu, ekhokelela kwisiphumo esibanzi se-stereo.Ukongeza, kukho iiteknoloji ezimbini zokuphucula isandi: iteknoloji ye-servo ye-electromechanical esebenzayo (ngokusisiseko kusetyenziswa umgaqo we-Helmholtz resonance), i-BBE ye-high-definition plateau ye-high-definition ye-plateau yokuvelisa iteknoloji ye-teknoloji kunye ne-"fax yesigaba" zobuchwepheshe, nazo zinefuthe elithile ekuphuculeni umgangatho wesandi.Kwizithethi ze-multimedia, i-SRS kunye ne-BBE iteknoloji kulula ukuyisebenzisa kwaye ibe nemiphumo emihle, enokuphucula ngokufanelekileyo ukusebenza kwezithethi.

Ithoni

Ibhekisa kumqondiso onezandi zezandi ezithile nezidla ngokuzinza (i-pitch), ngokuthetha ngomlomo, ithoni yesandi.Ikakhulu ixhomekeke kubude bobude.Kwisandi esinobude obufutshane, indlebe yomntu isabela ngesandi esiphakamileyo, ngoxa kwisandi esinobude obude, indlebe yomntu isabela ngesandi esiphantsi.Utshintsho kwi-pitch kunye ne-wavelength ngokusisiseko yi-logarithmic.Izixhobo ezahlukeneyo zidlala inowuthi efanayo, nangona i-timbre yahlukile, kodwa isandi sazo siyafana, oko kukuthi, isandi esisisiseko sesandi siyafana.

Timbre

Imbono yomgangatho wesandi ikwaluphawu lweempawu zesandi esinye esahlulayo kwesinye.Xa izixhobo ezahlukeneyo zidlala ithoni efanayo, i-timbre yazo inokwahluka kakhulu.Oku kungenxa yokuba amaza abo asisiseko ayafana, kodwa amacandelo e-harmonic ahluke kakhulu.Ke ngoko, i-timbre ayixhomekeke kuphela kumaza asisiseko, kodwa ikwanxibelelene ngokusondeleyo ne-harmonics eyinxalenye yesangqa esisisiseko, esenza isixhobo ngasinye somculo kunye nomntu ngamnye abe ne-timbre eyahlukileyo, kodwa eyona nkcazo ixhomekeke ngakumbi. kwaye unokuziva endaweni engaqondakaliyo.

Unamandla

Umlinganiselo weyona nto inamandla ukuya kweyona ibuthathaka kwisandi, ebonakaliswa nge-dB.Umzekelo, ibhendi inoluhlu oluguquguqukayo lwe-90dB, okuthetha ukuba eyona ndawo ibuthathaka inamandla angama-90dB angaphantsi kuneyona ndawo ingxolayo.Uluhlu lweDynamic lumlinganiselo wamandla kwaye alunanto yakwenza nenqanaba elipheleleyo lesandi.Njengoko bekutshiwo ngaphambili, uluhlu oluguquguqukayo lwezandi ezahlukeneyo kwindalo nalo luguquguquka kakhulu.Umqondiso wentetho jikelele umalunga ne-20-45dB kuphela, kwaye uluhlu oluguquguqukayo lwezinye ii-symphonies lunokufikelela kwi-30-130dB okanye ngaphezulu.Nangona kunjalo, ngenxa yemida ethile, uluhlu oluguquguqukayo lwenkqubo yesandi alufane lufikelele kuluhlu oluguquguqukayo lwebhendi.Ingxolo yendalo yesixhobo sokurekhoda imisela esona sandi sibuthathaka sinokurekhodwa, ngelixa ubukhulu bomthamo wesignali (inqanaba lokuphazamiseka) lwenkqubo lunciphisa isandi esinamandla.Ngokuqhelekileyo, uluhlu oluguquguqukayo lwesignali yesandi lusetelwe kwi-100dB, ngoko ke uluhlu oluguquguqukayo lwezixhobo zomsindo lunokufikelela kwi-100dB, into enhle kakhulu.

I-harmonics iyonke

Ibhekisela kumacandelo e-harmonic eyongezelelweyo yesignali yemveliso ebangelwa ngamacandelo angenawo umgca kunesignali yokufaka xa umthombo wesignali yomsindo udlula kwi-amplifier yamandla.Ukugqwethwa kwe-Harmonic kubangelwa yinto yokuba inkqubo ayilungelelananga ngokupheleleyo, kwaye siyivakalisa njengepesenti yengcambu ye-square ye-harmonic esanda kongezwa icandelo le-harmonic kwixabiso le-rms yophawu lokuqala.
