Wonjezerani

Zimatanthawuza ngati woyankhulira amathandizira kulowetsa kwa ma channel ambiri panthawi imodzi, kaya pali mawonekedwe owonetsera oyankhula mozungulira, kaya ali ndi ntchito yolowetsa USB, ndi zina zotero. njira zoyezera momwe ntchito ikukulirakulira.Mawonekedwe a olankhula ma multimedia wamba makamaka amaphatikiza ma analogi ndi ma interfaces a USB.Zina, monga ma optical fiber interfaces ndi njira zatsopano zolumikizirana ndi digito, sizodziwika kwambiri.

Zomveka

Matekinoloje odziwika bwino amtundu wa 3D amaphatikizapo SRS, APX, Spatializer 3D, Q-SOUND, Virtaul Dolby ndi Ymersion.Ngakhale ali ndi njira zosiyanasiyana zogwirira ntchito, onse amatha kupangitsa anthu kumva zomveka bwino zamitundu itatu.Zoyamba zitatu ndizofala kwambiri.Zomwe amagwiritsa ntchito ndi chiphunzitso cha Extended Stereo, chomwe ndikuwonjezeranso chiwongolero cha mawu kudzera muderali, kuti omvera amve kuti chiwongolero chazithunzi chikufikira kunja kwa okamba awiriwo, kuti awonjezere chithunzi cha mawu ndikupanga. anthu ali ndi mphamvu zakuthambo komanso mawonekedwe atatu, zomwe zimapangitsa kuti pakhale stereo yayikulu.Kuphatikiza apo, pali umisiri wowonjezera wamawu awiri: ukadaulo wogwiritsa ntchito wamagetsi amagetsi amagetsi (makamaka pogwiritsa ntchito mfundo ya Helmholtz resonance), ukadaulo wa BBE wotanthauzira mawu amtundu wapamwamba kwambiri komanso ukadaulo wa "phase fax", zomwe zimathandizanso kuwongolera mawu.Kwa olankhula ma multimedia, matekinoloje a SRS ndi BBE ndi osavuta kugwiritsa ntchito komanso amakhala ndi zotsatira zabwino, zomwe zimatha kusintha magwiridwe antchito a okamba.

Kamvekedwe

Kutanthauza chizindikiro chokhala ndi utali wokhazikika komanso wokhazikika (mawu), kuyankhula momveka bwino, kamvekedwe ka mawu.Zimadalira makamaka kutalika kwa mafunde.Kwa phokoso lokhala ndi utali waufupi, khutu la munthu limayankha ndi mawu okwera, pamene phokoso lokhala ndi utali wautali, khutu la munthu limayankha ndi mawu otsika.Kusintha kwa phula ndi wavelength kwenikweni ndi logarithmic.Zida zosiyanasiyana zimayimba nyimbo yofanana, ngakhale kuti timbre ndi yosiyana, koma mamvekedwe ake ndi ofanana, ndiye kuti, funde lalikulu la phokoso ndilofanana.

Timbre

Lingaliro la khalidwe la phokoso ndilo khalidwe la khalidwe la phokoso lomwe limasiyanitsa ndi lina.Zida zosiyanasiyana zikayimba mawu ofanana, timbre yawo imatha kukhala yosiyana kwambiri.Izi zili choncho chifukwa mafunde awo ofunikira ndi ofanana, koma zigawo za harmonic ndizosiyana kwambiri.Chifukwa chake, timbre sizimangotengera mafunde oyambira, komanso zimagwirizana kwambiri ndi ma harmonics omwe ali gawo lofunikira la mafunde oyambira, zomwe zimapangitsa chida chilichonse choyimbira ndi munthu aliyense kukhala ndi timbre yosiyana, koma kufotokoza kwenikweni kumakhala koyenera. ndipo angamve M'malo mwachinsinsi.

Zamphamvu

Chiŵerengero cha amphamvu kwambiri ndi ofooka m’mawu, osonyezedwa mu dB.Mwachitsanzo, gulu lili ndi 90dB yosinthika, zomwe zikutanthauza kuti gawo lofooka kwambiri limakhala ndi mphamvu zochepera 90dB kuposa gawo lofuula kwambiri.Dynamic range ndi chiŵerengero cha mphamvu ndipo alibe chochita ndi mtheradi mlingo wa phokoso.Monga tanenera kale, kusinthasintha kwamitundu yosiyanasiyana m'chilengedwe kumasinthasintha kwambiri.Chizindikiro cholankhulidwa chimakhala pafupifupi 20-45dB, ndipo ma symphonies ena amatha kufika 30-130dB kapena kupitilira apo.Komabe, chifukwa cha zofooka zina, kusinthasintha kwa makina omveka sikufika pamtundu wosinthasintha wa gululo.Phokoso lachidziwitso cha chipangizo chojambulira chimatsimikizira phokoso lofooka kwambiri lomwe lingathe kulembedwa, pamene mphamvu yaikulu ya siginecha (yosokoneza) ya dongosolo imalepheretsa phokoso lamphamvu kwambiri.Nthawi zambiri, kusinthasintha kwa siginecha yamawu kumayikidwa ku 100dB, kotero kuchuluka kwa zida zomvera kumatha kufika 100dB, zomwe ndi zabwino kwambiri.

Ma harmonics onse

Zimatanthawuza zigawo zina za harmonic za chizindikiro chotulutsa zomwe zimayambitsidwa ndi zinthu zopanda mzere kusiyana ndi chizindikiro cholowetsa pamene gwero la ma audio likudutsa pa amplifier ya mphamvu.Kusokonekera kwa Harmonic kumachitika chifukwa chakuti makinawo sali ofanana kwathunthu, ndipo timachiwonetsa ngati gawo la muzu wotanthauza lalikulu la gawo lomwe langowonjezeredwa kumene ku mtengo wa rms wa chizindikiro choyambirira.
