Hoʻonui

E pili ana i ka kākoʻo ʻana o ka mea ʻōlelo i ka hoʻokomo like ʻana o nā kahawai he nui, inā he interface hoʻopuka no nā mea ʻōlelo hoʻopuni passive, inā he hana hoʻokomo USB kāna, a pēlā aku. ʻO ka helu o nā subwoofers i hiki ke hoʻopili ʻia i nā mea ʻōlelo hoʻopuni waho kekahi o nā pae hoʻohālikelike e ana i ka hana hoʻonui. ʻO nā interface o nā mea ʻōlelo multimedia maʻamau e pili ana i nā interface analog a me nā interface USB. ʻO nā mea ʻē aʻe, e like me nā interface fiber optical a me nā interface kikohoʻe hou, ʻaʻole maʻamau loa.

Ka hopena leo

ʻO nā ʻenehana hopena leo 3D maʻamau e komo pū ana me SRS, APX, Spatializer 3D, Q-SOUND, Virtaul Dolby a me Ymersion. ʻOiai he ʻokoʻa ko lākou mau ʻano hoʻokō, hiki iā lākou āpau ke hoʻomaopopo i nā kānaka i nā hopena leo ʻekolu-dimensional. ʻOi aku ka maʻamau o nā mea mua ʻekolu. ʻO ka mea a lākou e hoʻohana ai, ʻo ia ke kumumanaʻo Extended Stereo, ʻo ia hoʻi ke hana hou ʻana i ka hōʻailona leo ma o ke kaapuni, i manaʻo ai ka mea hoʻolohe ua hoʻonui ʻia ke kuhikuhi o ke kiʻi leo i waho o nā mea ʻōlelo ʻelua, i mea e hoʻonui ai i ke kiʻi leo a loaʻa i nā kānaka ka ʻike ākea a me ke ʻano ʻekolu-dimensionality, e hopena ana i ka hopena stereo ākea. Eia kekahi, aia ʻelua mau ʻenehana hoʻonui leo: ʻenehana servo electromechanical hana (me ka hoʻohana ʻana i ke kumumanaʻo resonance Helmholtz), ʻenehana ʻōnaehana hana hou leo ​​plateau kiʻekiʻe BBE a me ka ʻenehana "phase fax", nona kekahi hopena i ka hoʻomaikaʻi ʻana i ka maikaʻi o ke kani. No nā mea ʻōlelo multimedia, ʻoi aku ka maʻalahi o ka hoʻokō ʻana i nā ʻenehana SRS a me BBE a loaʻa nā hopena maikaʻi, hiki ke hoʻomaikaʻi maikaʻi i ka hana o nā mea ʻōlelo.

Leo

Pili ia i kahi hōʻailona me kahi nalu kikoʻī a paʻa mau (pitch), ma ke ʻano maʻamau, ke kani o ke kani. Pili nui ia i ka nalu. No ke kani me kahi nalu pōkole, pane ka pepeiao kanaka me kahi pitch kiʻekiʻe, ʻoiai no ke kani me kahi nalu lōʻihi, pane ka pepeiao kanaka me kahi pitch haʻahaʻa. ʻO ka loli o ka pitch me ka nalu he logarithmic maoli. Hoʻokani nā mea kani like ʻole i ka leo like, ʻoiai he ʻokoʻa ke kani, akā like ko lākou pitch, ʻo ia hoʻi, like ka nalu kumu o ke kani.

Timbre

ʻO ka ʻike ʻana i ke ʻano o ke kani ke ʻano o kekahi kani e hoʻokaʻawale iā ia mai kekahi. Ke hoʻokani like nā mea kani like ʻole i ke kani like, hiki ke ʻokoʻa loa ko lākou leo ​​kani. ʻO kēia no ka mea like ko lākou mau nalu kumu, akā ʻokoʻa loa nā ʻāpana harmonic. No laila, ʻaʻole hilinaʻi wale ka leo kani i ka nalu kumu, akā pili loa hoʻi i nā harmonics he ʻāpana koʻikoʻi o ka nalu kumu, ka mea e hana ai i kēlā me kēia mea kani a me kēlā me kēia kanaka i kahi leo kani ʻokoʻa, akā ʻoi aku ka pilikino o ka wehewehe maoli a manaʻo paha he mea pohihihi.

ʻOi aku ka ikaika

ʻO ka lakio o ka mea ikaika loa i ka mea nāwaliwali loa i loko o kahi leo, i hōʻike ʻia ma dB. No ka laʻana, he 90dB ka laulā dynamic o kahi hui leo, ʻo ia hoʻi, he 90dB ka liʻiliʻi o ka mana o ka ʻāpana nāwaliwali loa ma mua o ka ʻāpana leo nui loa. ʻO ka laulā dynamic ka lakio o ka mana a ʻaʻohe ona pili i ka pae piha o ke kani. E like me ka mea i ʻōlelo ʻia ma mua, he loli loa hoʻi ka laulā dynamic o nā leo like ʻole ma ke ʻano. ʻO ka hōʻailona ʻōlelo maʻamau ma kahi o 20-45dB wale nō, a hiki i ka laulā dynamic o kekahi mau symphony ke hiki i 30-130dB a ʻoi aku paha. Eia naʻe, ma muli o kekahi mau palena, ʻaʻole hiki pinepine ka laulā dynamic o ka ʻōnaehana leo i ka laulā dynamic o ka hui leo. ʻO ka walaʻau kūlohelohe o ka mea hoʻopaʻa leo e hoʻoholo i ke kani nāwaliwali loa hiki ke hoʻopaʻa ʻia, ʻoiai ʻo ka nui o ka hōʻailona (pae distortion) o ka ʻōnaehana e kaupalena i ke kani ikaika loa. Ma ke ʻano laulā, ua hoʻonohonoho ʻia ka laulā dynamic o ka hōʻailona leo i 100dB, no laila hiki i ka laulā dynamic o nā lako leo ke hiki i 100dB, he mea maikaʻi loa ia.

Nā harmonika āpau

Pili i nā ʻāpana harmonic keu o ka hōʻailona hoʻopuka i hoʻokumu ʻia e nā ʻāpana nonlinear ma mua o ka hōʻailona hoʻokomo i ka wā e hele ai ke kumu hōʻailona leo ma o ka mea hoʻonui mana. Hoʻokumu ʻia ka distortion Harmonic e ka ʻoiaʻiʻo ʻaʻole linear loa ka ʻōnaehana, a hōʻike mākou iā ia ma ke ʻano he pakeneka o ke kumu awelika square o ka huina harmonic i hoʻohui hou ʻia i ka waiwai rms o ka hōʻailona mua.
