Discretization i loko o kēia Panel

I keia la ka kikohoʻe manaʻo, ka mea hōʻikeʻikeʻuʻuku ia mea ku pono i ka mea i ka ike ua maheleia i loko o kekahi mau Eia kekahi laʻana i mauʻanuʻu. I ka pau, i kekahi o na kumu hoohalike i loko o keia hihia o ka wahi o nā kiko kiʻi ma luna o ka mua, o ka lua o kāna kiʻi i kekahi kumu i loko o ke kiʻi, a hiki ke hai hou ma luna o ka wahi nui paha a i hoʻololi ma hope o kekahi mau helu o nā kiko kiʻi i loko o ka transverse a lonikū ao ao.

No ka mea, ÿo ka mea e ole maopopo i ka mea hōʻikeʻikeʻuʻuku a me ka wā e kupu ana, e hiki ke haawi aku i ka kekahi laʻana. I ka loaʻa mea lawa loaʻa nui o ka helu ana o nā kiko kiʻi, e lawe pololei 'ike i ke kiʻi, ma ka a ina ia mea,ʻaʻole ma ka mea maikaʻi e like ai. Ma ka maʻamau mana mea makemake e lawa wale, e koho i kekahi olelo hooholo kiekie ae, pela kaulike ai ka malama ana o ke koi 'ia ka helu o nā kiko kiʻi no ka EYI wahi i loko o ka Hawaii photo me ka kekahi pololei, a ina makemake ole e lawa i ka helu ana o nā kiko kiʻi, ua hiki e ike i ka uuku o ka oihana mua o ke kiʻi.

Eia naʻe, ma ka ike maopopo i kēia mea,ʻaʻole oiaio. mea hōʻikeʻikeʻuʻuku kumumanaʻo hākālia nō ia ma ka ike maopopo i ke kulana mea nui oi io, a ina mākou e ole i lawa ka helu ana o nā kiko kiʻi ma ka mea e hana i kekahi kiʻi, a laila, i ke kiʻi e like ai, e deteriorate noke.

Ehia na nā kiko kiʻi 'oe e pono ai?

Lawe no ka like o ka pilikia ka wā he mea he kiʻi pono 20ʻeleʻele, a keʻokeʻo laina kēlā me ka laula o ka 5 nā kiko kiʻi. Ma keia hihia, ina ma ka liʻiliʻi loa hoʻokahi kiʻi kiko ua hoakaka no kela a me keia laina, ke kiʻi hiki ke mālama '. Maoli ai, ina na nā kiko kiʻi mai i haule pono i loko o ka waena o kēlā me kēia laina, ma keia hihia, e huli kēlā me kēia kiʻi kiko poohina, i keʻokeʻo aole hoi i eleele, a me kona malu mua 'ana, e hilinaʻi ma ana i ke kiʻi kiko ua hoʻonoho i pili i ka laina.

Inā o ka helu ana o nā kiko kiʻi i loko o ke kiʻi, e emi iho, laila, i loko o ia hihia, i kekahi o ia e e hoakaka ia ma waena o nā laina, no laila, i ke kiʻi 'ōili mai ma luna o ke kumu e, e noke oko ma luna o ka mea hoʻopili mea i loko o ka wā mawaena ma waena o ka laina, a me ka helu o nā kiko kiʻi. O ka holo ana, i kēia kiʻi e ole e he mau nā'ōlelo o ka palapala, e like me ka mea maʻamau 'ole o ka laina ano e noticeably hihia hoʻi. He keia kŰia kapaia "ʻikepili mea hōʻikeʻikeʻuʻuku" ma ka 'oihana koʻikoʻi a hanohano.

He aha e hana ai?

E hoʻoponopono i kēia pilikia, ia mea pono, e hoopalupalu no au i ke kiʻi mua oe i emi ka helu o nā kiko kiʻi. Penei, e hiki loa kiʻi pohaku uinihepa, o ka pahikaua kihi ma luna o kēlā me kēia laina, a me na nā kiko kiʻi ke lawe waena nā loina. Ma nā hua'ōlelo, ke kiʻi lilo softer, akā, hoopaa iho la i ka pono manaʻo o ke kiʻi.

'Aʻole kēia he aha ka Pehea ke kiʻi?

O ka holo ana, hiki ke loaʻa he pohihihi keia i loko o nā kiʻi o nā maoli nä mea i ka hai, a maʻamau 'ole o ka laina - kā lākou alo ua pinepine kaupalena' ia nā kiʻi o naʻimi hoʻopunipuni nā hale e like me hale a me ka ukana. Eia naʻe, ma kekahi hihia, no ka mea hōʻikeʻikeʻuʻuku hohonu hiki e kilakila, no laila, ua hookoia ua mau käpae 'hana i kekahi pana mea.

He waiwai 'ana i kumumanaʻo o ka mea ana i ke kiʻi e like ai hiki e loa okoa, a hiki ina ka mea, i ka ia helu ana o nā kiko kiʻi. Ma hope o nā mea a pau, mawaena o na mea a pau, i ka likeʻole ma waena o nā kiʻi i kekahi e ka e like pehea ka mea i loaa. No ka laʻana, ma kekahi hihia, i ke kiʻi i kekahi mau mea e mitigated e hele ia ma ka haʻahaʻa e hele Kānana e loaa waena kiʻi kiko aiee mua emi o ka nui, akā, i kekahi kiʻi i ke wale hoemi i ka nui me ka hana ana i ka mea, pela i nā loli aʻaʻole e hāʻawi mai waena aiee ma nā palena o nā mea ma laila nō loa abrupt loli ma ka'ālohilohi.

Pehea e nānā?

E maopopo pehea e hana, e lawa e lawe i kekahi kiʻi, a laila, e ke kope. Original Kānana ka wā resizing me ke koho ana i laila,-kapaʻiaʻelua-cubic kānana, i mea i loaʻa i loko o ka hae Adobe Photoshop. Penei, i ke kiʻi e e mitigated. I loko nō o ka na hiohiona emi ana i loko o ke kiʻi kiko, nā mahele ma waena o tonalities e ho'ōla hou malimali, a he pono no ka mea i loaʻa ka helu o nā kiko kiʻi.

Ma hope iho o ia, ua i kekahi kope o nā kiʻi emi mua, e olelo oukou, mai ka 30% o ka palapala nui, ka hoʻohana 'ana i ke koho "kokoke hoalauna wahi" i loko o ka ia polokalamu. I keia hana ultimately, e haawi aku oe i ka mea hōʻikeʻikeʻuʻuku kanawai, a e e hoikeia.

Audio la'ana

Audio Laʻana - he kānana o ka leo nalu mua ia e ke hoolaia me ka leo waihona. Ma nā hua'ōlelo, i ka pale umauma hoʻokahi waihona mea,ʻaʻole he kope mau o ke kani nalu, akā, He kokekau wale wale. Ma ka kekahi lima, me ka leo hāpana e hoʻolako i ka definite emi i loko o ka mālama waihona, akā, ma ka 'ē aʻe lima he mau puu o kani kuekueni, i hiki ole pono e waiho ma ka paakiki pā hōkū.

Oia kani kānana i kapaia "mea hōʻikeʻikeʻuʻuku alapine (frequency)". Ua mea waiwai 'ana i kumumanaʻo i ka mea wale nō i loko o keʻano he meaʻaʻohe leo o keia kanawai, aole nae mau ike e pili ana ia. Mea hōʻikeʻikeʻuʻuku ana - o ke kau ana o kekahi mau 'maka aha i ke kani nalu, a me ka mooolelo wale kekahi kī oihana mua.

Record loa a pau o na ale kani makemake e he paʻakikī. Ia mea no keia mea, e nui aku hiki ke loaʻa ke kahua kahi i i ka mau-Kanal kani i hoʻopaʻa 'ia me ka mea hōʻikeʻikeʻuʻuku alapine (frequency) o 44,1 kHz. Ka hope loa pinepine i waeʻia, e like me kēia mea o ka maikaʻi loa koho.

I ka mea, e noonoo pono i ka leo aaioee, ia mea pono e uku kūikawā noonoo i na mea kiko'î i helu kuʻina hohonu a me ka hāpana ana, no ka mea, ua kiekie ae na holo 'awelika, me ka oi aku o ka mīkini neaiae , e hoʻopili like e Analog.
