Audio file - ndi mtundu ndi kutambasuka iliyonse?

anthu ochepa mukudziwa kuti kuyambira nthawi ya zosayembekezereka wa oganiza makompyuta luso zotsogola. Tsopano ndi onse amakonda, kuti mayendedwe ndi ankasewera pa nkhani yabwino ku mtundu wa MP3. Ndipotu, sizinali nthawi zonse, ndi matepi makompyuta wakhala lolunjika yekha kugwiritsa ntchito mphamvu dongosolo. masewera amene analenga pansi DOS, ntchito mu mode izi.

Phokoso loyamba

Ndipotu, woyamba pa nkhani yopanga phokoso akanakhoza "kutigwira" ku kachitidwe chi computer, chifukwa cha maonekedwe a dongosolo ndi DOS ndi wosazindikira masewera, cholinga ntchito mu zimenezo. Osati kutchula Super Mario, anaitenga ku Nintendo, panali ndi 3D-oponya mivi monga Duke Nukem, amene anali kuyesera kupereka akamanena za kosewera masewero ndi phokoso sitiriyo. Komabe, sanapange alibiretu kuganiza, nyimbo akatswiri ndi kusintha mayendedwe zomvetsera anakhalabe kufikako.

Zikamera wa codec

Kukwera A zinachitika pamene codec chilengedwe kuti compresses owona ndi kusewera zonse zimene zingagwedezeke, zalembedwa kuchokera maikolofoni amasulidwe. Ndi nthawi kutambasuka kwa zomvetsera anali mmodzi yekha chojambula chifaniziro, ndicho WAV (kuchokera acronym "yoweyula").

Komabe, WAV-file amatenga malo kwambiri pa galimoto mwakhama. Tiyeni tingonena, ngakhale masiku ano, njanji mu mtundu amenewa kwa mphindi zisanu, phokoso mwina "kulemera" kwa 25-50 MB, malingana ndi khalidwe. Patapita nthawi, zinadziwika kuti kumveka file kukula ayenera kukhala waukulu kwambiri.

zomvetsera situdiyo

Tsopano pang'ono za umisiri ndi. Kumbali ya kujambula ndi file Audio - ichi ndi chimene aliyense woimba akhoza kusewera mu pompopompo ndi mbiri ndi kompyuta kapena chipangizo wapadera mu situdiyo. Kodi mfundo. Mfundo yakuti mwamtheradi onse mapulogalamu lakonzedwa kuti gawo kujambula ku situdiyo, kugwiritsa ntchito WAV mtundu, ngati iwo akanati ankakonda kuchita popanda izo. Nthawi zina, akhoza basi lidzasinthidwa ina (pambuyo kujambula). Nthawi zambiri izi zimachitika ndi mtundu wa mapulogalamu (ovomereza Zida), amene anafuna kuti ntchito kokha Mac Os X. kachitidwe

Koma ngakhale mu nkhani iyi, zomvetsera file - mbali ya mtundu koyamba, amene sasiya kufunika kwake. Onse amayankhula chabe. Ndipotu mlingo katswiri wa ku situdiyo ya palibe amene amagwiritsa owona wothinikizidwa, akuganiza kuti parody cha phokoso koyera. Kumene, kutambasuka kwa zomvetsera pambuyo kujambula akhoza kukhala chilichonse. Nthawi zina, WAV-owona kungakhale zosakhalitsa. Kuti, pambuyo Polemba amaika, amangoika zichotsedwa kwa litayamba mwakhama.

akamagwiritsa Modern zomvetsera

Today pa codecs msika ndi yogwirizana ndi zipangizo zomvetsera kapena osewera mapulogalamu, ndithu kwambiri. Komabe, ngati wina anaona, ngakhale kufotokoza ena mwa mafilimu kukumana codecs monga AAC, H.264, kapena chinachake chonga izo. Chiziyambitsa mavuto nokha. Chakwanira kukhazikitsa pa kompyuta Baibulo atsopano, nkuti, K-Lite Codec Pack ndi vuto idzapita paokha. Koma zimenezi si zofunika. Amatanthauza 'kala' ikusonyeza ndi decoding wa Audio owona audio. Ndipo zimenezi zingachitikire ndithu zambiri mavuto.

Audio kubwezeretsa: makhalidwe waukulu

akamagwiritsa file Audio mwachindunji zokhudzana ndi magawo awo amene analengedwa kapena kupulumutsidwa poyamba. Koma osati zimakhudzira khalidwe la kubalana.

Choyamba, muyenera khutu ku makhalidwe pafupipafupi. Mapulogalamu kupereka kumvetsa zimene ndi file Audio - izi pafupipafupi wamba kapena ayankhe matalikidwe mu mawonekedwe a mafunde, poyamba chinaonekeranso pa oscilloscope chomwecho. Makhalidwe waukulu mu nkhani iyi ndi kubwezeretsa kuya, m'kukoma Akamva (16, 24, 32), mlingo chimango (a muyeso deta kubwezeretsa pa wachiwiri), makamaka kwa 32 450 kbit / s, ndi zochepa chabe pamalangizo pafupipafupi kuti 96 kHz.

Nthawi zambiri, mu muyezo analandira pafupipafupi 44.100 Hz, ngakhale oyimba akatswiri ndi opanga ntchito dongosolo la ukulu wa 48 kapena 96 kHz.

Popanda imene sitingathe kuchita

Tsopano pang'ono zoti yowonjezera file zomvetsera ali ndi moyo wautali kwambiri. Iwo sanamulandire kulankhula kokha za MP3, chifukwa apamwamba khalidwe la ntchito akadali FLAC mtundu.

Iwo ali ndi zovuta zake. mfundo ndi yakuti ngati dongosolo si alimbane ndi codec makamaka, nthawi zambiri kusintha pakati pa mayendedwe kadzakulakani. Ziri kulankhula, player pulogalamu iliyonse adzalandira mbiri ngati njanji lonse audio. The AIMP chomwecho poyamba amakhazikitsa codecs yake ndi dongosolo mwa mawu wotani phokoso imakonzanso player akhoza kusewera.

Choncho, ngati inu anaganiza kukopera matepi mtundu uwu, inu muyenera kuonetsetsa kuti player wa mudzazindikira. Komanso, pafupipafupi ayankhe akhoza zimamuchulukira player aliyense (makamaka pamene ntchito lachitatu chipani pulagi-ins ndi yophunzitsa).

Audio processing ndi subtleties kugwirizana ndi ndondomeko iyi

Tsopano yekha ndiye mtengo kuyang'ana mu vuto la mmene kubala processing wailesi, ngakhale njira pachiyambi likupezeka mu video. Kuti tichite zimenezi, pali zambiri mapulogalamu phukusi, Pakati m'pofunika kutchula mtundu wa pulogalamu Sound Forge, Adobe mayeso, Mixcraft, etc.

onse amamvera mfundo yomweyi ya processing phokoso - ndicho, chifaniziro cha mtundu uliwonse mu mawonekedwe a "mafunde".

Kusintha njira imeneyi zimathandiza inu osati kumvetsa zimene "mitundu ya zomvetsera", komanso kuzindikira kuti zomvetsera aliyense akhoza kusungidwa mu njira oyenera okha.

Apa pali zida ambiri osati kwa kusintha wailesi, komanso kugwiritsa ntchito ndalama zina, omwe tsopano amatchedwa "pulagi-ins» (pulogalamu yowonjezera). Mu mawu ena, gulu lina ntchito zikugwirizana ndi mawonekedwe programmatically pakati phukusi woimira kuwonjezera magwiridwe zofunika kwambiri. Processing zomvetsera ndi ntchito awo amasandulika chipangizo kuposa ntchito ndalama mwini wa dongosolo.

Pomaliza, munthu akhoza kudziwa kuti phokoso file - ndicho chimene ife tikumva lero pa wailesi chomwecho. Ngakhale kulemba kukambirana pa tepi, ife akupeza phokoso file. Mu ena mtundu akulu mafoni angasinthe. Mwachitsanzo, kutambasuka kwa zomvetsera anakhalabe ngakhale mu lotha mtundu AMR.

Chizindikiro chomaliza cha phokoso

Tsopano m'pofunika kukhala chakuti lero mitundu yonse owona matumizidwe ophatikizika amawu, nyimbo ndi zithunzi zikhoza anatsegula ntchito ofunsira kuti achite mtanda nsanja kugwirizana pakati pa zigawo zikuluzikulu zofunika kachitidwe.

Mwachitsanzo, ngati pamaso pa WAV-file chabe yoweyula panopa zogwirizana mu mtundu wina uliwonse mu njira yomweyo. Kaya mtundu, ambiri mapulogalamu mankhwala amatha kutsegula OGG yomweyo, imene wosasintha kungoti amalephera ntchito (popanda codec anaika).

Ndipotu, zonse ndi yosavuta. Ngati inu mukumvetsa zimene phokoso (Audio) owona, ndiye inu mukhoza ngakhale kulemba nyimbo, kodi kwenikweni, chinkhoswe ndi DJs woimira dubstep kapena chinachake chonga izo. Chinthu chachikulu - khamu la anthulo, "m'kati".

Apanso, ali zina zabwino zake. mfundo ndi yakuti mu owona ano madansi phokoso mu mawonekedwe a mbali ng'oma akhoza ma pachiyambi. Kuti tichite zimenezi, ndiye pali wapadera "poyimitsa" kuima DJs.

Ndi mfundo woimba katswiri wa maganizo, phokoso file kuti analengedwa madansi, pamene anthu mafunde, sizingafanane ndi mfundo mwayi "moyo" asangalatsi.

Ngakhale mabanki zipangizo otchuka synthesizers kwambiri ndi workstations wa mndandanda Roland Fantom X (chilichonse zino) kapena Yamaha motif X8 (ndi apamwamba) tsopano zikupezeka SF2 mtundu.

Ndithudi, izi si chilichonse chimene angathe kupanga zida akatswiri. Koma! Ngati munthu wina nthawi ankaimba nawo, nthawi yomweyo zimaonekeratu kuti pulogalamu phokoso file pamene kabisidwe si losiyana kwa phokoso pachiyambi ngakhale SF2 mtundu.

Pomaliza, tikuona kuti zomvetsera file - ndi malamulo synthesizer kuti ali MIDI-kapangidwe (mkati), kugawa zipangizo za njanji wina, ndipo zotsatira pa ena. Mulimonsemo, pali zigawo chilengedwe kuti kuphatikiza zonse mwa zizindikiro zimenezi. Ndipo mwana'yo kulekana kwa mayendedwe pa "Zida" ndi "Zotsatirapo."
