Mayeso a kuzindikira kamvekedwe ka nyimbo: njira

Zimene amayezera

Mulingo wochepa wosiyanitsira kumene kamvekedwe kakulowera (kusiyana komwe kamamveka molondola pafupifupi 70.7% ya nthawi), kulondola pobwereza kayendedwe kaifupi, ndi (posankha) kutchula matoni popanda choyerekezera (kuzindikira kamvekedwe koyambirira).

Mmene amachitira

Poyamba pamamveka manotsi 4 okwera motsatizana kuti musankhe voliyumu yabwino. Mawu onse amapangidwa mu msakatuli (Web Audio): mawu ovuta okhala ndi ma harmoniki 1 mpaka 4, pa milingo ya mphamvu ya 1, 0.5, 0.3 ndi 0.15. Gawo 1, kamvekedwe: mawu awiri a 350 ms (okhala ndi kuchepetsedwa kwa mawu kwa 25 ms) olekanitsidwa ndi mpata wa 400 ms. Mawu oyamba amasankhidwa mwachisawawa motsatira log-uniform pakati pa 330 ndi 660 Hz pa mayeso aliwonse; mawu achiwiri amakhala okwera kapena otsika (50/50) malinga ndi kusiyana komwe kukugwiritsidwa ntchito panthawiyo. Wosewera amayankha kuti Wokwera kapena Wotsika (pogwiritsa ntchito mabatani kapena makiyi a mivi); yankho lolondola kapena lolakwika limasonyezedwa pambuyo pa yankho lililonse. Pali mayesero oyeserera osankha a 300 ndi 200 masenti. Mayeso oyenda uku ndi uku amayamba ndi kusiyana kwa 100 masenti; mayankho olondola 2 motsatizana amachepetsa kusiyanako, ndipo kulakwitsa 1 kumakukulitsa; kusiyanako kumasinthidwa ndi chinthu cha 2 mpaka pakusintha koyamba kwa njira, kenako ndi sikweya mizu ya 2; malire ake ndi 0.5 mpaka 400 masenti; mayesowo amaima pakakhala kusintha kwa njira 10 kapena mayesero 60. Gawo 2, kayendedwe: pali kayendedwe ka kudina 5, ndipo kalikonse kamaseweredwa kawiri ndi magawo 4 a chete pakati pa kuseweredwa kwake, kenako mumabwereza pogogoda (batani, Space kapena Enter); kulowetsa mayankho kumatsekedwa pakadutsa 2.5 s kuchokera pa kugogoda komaliza komwe kumayembekezeka. Gawo 3, kusankha kutchula manotsi: mawu amodzi-amodzi 12 pakati pa C3 ndi B5 (dzina la noti lomwelo silibwerezedwa kawiri motsatizana), ndipo mumatchula noti iliyonse pogwiritsa ntchito kiyibodi ya pa sikirini ya octave imodzi; palibe mawu osonyeza kamvekedwe koyerekezera ndipo palibe ndemanga pa mayankho. Kutuluka pa tabu ya msakatuli kumathetsa mayesowo.

Miyezo ya makonzedwe

Kuwerengera zotsatira

Kamvekedwe: mulingo wochepa = avereji ya ma geometric ya malo 6 omaliza amene njira inasinthira, mu cents (imasonyezedwanso ngati kusiyana kwa mafupipafupi mwa peresenti); pamafunika kusintha kwa njira 2. Ichi ndi chigoli chachikulu; chochepa ndi chabwino. Semitone imodzi ndi 100 cents. Kayendedwe: nthawi za pakati pa zogogoda zimasinthidwa kuti zonse pamodzi zifanane ndi kutalika kwa kayendedwe (liwiro siliganiziridwa); cholakwika pa njira iliyonse = avareji ya |nthawi yosinthidwa pakati pa zogogoda − nthawi ya kayendedwe| / nthawi ya kayendedwe pa mipata yake, ndipo mpata uliwonse umakhala ndi malire a 50%. Njira imawerengedwa kuti yafanana ngati cholakwika ndi 20% kapena kuchepera. Njira yokhala ndi zogogoda zolakwika pa chiwerengero chake siwerengedwa. Zomwe zimanenedwa: njira zofanana (pa 5), avareji ya cholakwika %, chiŵerengero cha liwiro (choposa 1 = pang'onopang'ono kuposa momwe chinaseweredwera). Matoni: dzina lenileni la noti limapeza 1, noti yosiyana ndi semitone imodzi imapeza 0.75 (monga mu Athos et al. 2007); chigoli % = mfundo / 12. Palibe kuyerekezera ndi osewera ena komwe kumawonetsedwa.

Malamulo ovomerezera mayeso ochitidwa

Seva imabwerezanso njira ya masitepe kuchokera pa mayankho olondola ndi olakwika ndipo imakana kuyesaku ngati kusiyana komwe kunaperekedwa sikunatsatire njirayo, ngati kamvekedwe koyamba kanali kunja kwa 330–660 Hz, kapena ngati njira ya masitepe sinathe (zosintha zosakwana 10 ndipo zoyesera zosakwana 60). Njira za kayendedwe ziyenera kubwera motsatira dongosolo ndipo nthawi zogogoda zisabwerere m’mbuyo. Gawo la matoni liyenera kukhala ndi maulendo 12 ndendende mkati mwa malire, kapena lisakhalepo. Seva imamanganso kuyesa kulikonse kuchokera pa mbiri yaiwisi (ndi nambala yoyambira ya kuyesako ngati ilipo) ndipo imawerengera chigoli yokha; mawu aliwonse a tsambali okhudza kulondola kapena kulakwitsa sanyalanyazidwa. Mbiri yosatsatira malamulo a masewerawa imakanidwa, ndipo palibe chomwe chimasungidwa. Zoyesera zosungidwa zingakhale ndi zizindikiro za khalidwe zomwe sizionetsedwa ndipo sizilepheretsa zotsatira: maulendo 10 kapena kuposerapo kuchokera ku adiresi imodzi ya IP, kusowa kwa chizindikiro cha mlendo, kusintha ma tab, ndi zizindikiro za makina (msakatuli wodziyendetsa wokha, liwiro losatheka, kusowa kwa zochitika zolowetsa, kapena nthawi yofanana kwambiri ngati ya makina).

Kusiyana ndi ntchito yakale yoyambirira

Kusiyanitsa kamvekedwe mu labotale kumagwiritsa ntchito mahedifoni oyezera, voliyumu yokhazikika ndipo nthawi zambiri kumachita mayesero angapo osinthira njira; apa mumayesa kamodzi pogwiritsa ntchito zokuzira mawu kapena mahedifoni anu, ndipo mumalandira ndemanga yankho lililonse likatha. Aka si Montreal Battery of Evaluation of Amusia kapena mayeso aliwonse ozindikira matenda. Gawo la kayendedwe ndi ntchito yaifupi yobwereza, osati mayeso ovomerezeka a kumva kugunda kwa nyimbo. Gawo la matoni limatsatira njira yoperekera zigoli ya Athos et al. (2007), koma limagwiritsa ntchito phokoso limodzi lopangidwa ndi kompyuta ndi matoni 12.

Zimene mayesowa sangathe kuyeza

Zokuzira mawu, mahedifoni, voliyumu ndi phokoso lakumbuyo zimasintha mulingo wochepa, monganso kusokonekera kwa chidwi ngakhale kamodzi kokha. Mulingo wochepa umakwera msanga munthu akamayeserera. Kuchedwa kwa chogwirika ndi kiyibodi kumakhudza kugogoda kwa kayendedwe. Si mayeso akumva ndipo sangathe kudziwa ngati munthu ali ndi amusia. Palibe miyezo yoyerekezera ya mtundu umenewu.

Zinenero ndi mmene zawunikidwira

Phokoso silidalira chinenero; mayina a matoni ndi malangizo akupezeka m’zinenero zonse za tsambali (Chingelezi ndi zinenero zina 99).
