Guqula MP3 kuya AIFF

Ngephutha yebo — i-stereo ihlala i-stereo, isilinganiso sesampula sakuqala (44.1 kHz, 48 kHz, njll.) sithunyelwe ku-AIFF output.

Yebo — umsindo ongenawo umonakalo uvame ukuba 5-10x omkhulu kunawo umsindo ongenawo umonakalo ngekhwalithi elinganayo. Phinda ubeke isinqumo se ~10 MB ngomzuzu AIFF versus ~1 MB ngomzuzu we-high-bitrate MP3.

Yebo — izihlungi ezingalahleki zigcina wonke ama-byte. Lindela ukuthi i-AIFF ibe ngu-3-8x ubukhulu be-MP3. Inani elingcono lizoba ukuthi akukho ukulahleka kwekhwalithi engaphezulu ekuhlelani noma ekuphindeni ukungenisa.

Akuna, futhi kufanelekile ukuba kucace: akukho okuzokwenzeka. I MP3 idlulele i-detail ngesikhathi sokuqothula kwayo okujwayelekile, futhi ukubopha okushiwo ku AIFF ongeke ulahlekelwa yilutho kugcina lokho - akukho okuningi. Ihele lithola izikhathi eziningi ezikhulu futhi lizwakala lifana. Kukhona ukunyakaza okulungile ngaphambi kokulungisa, ngoba AIFF ngeke ihlanganise isizukulwane sesithathu sezinto ezibonakalayo uma ukhipha. I-AIFF iyifomethi yokushintshana kwestudio ku-macOS, iphatha i-metadata kahle kunaleyo ye-WAV, futhi ingenisa ku-Logic ne-Pro Tools ngokushesha. I-MP3 ihlukaniswe ngokukhethekile yi-AAC ne-Opus nganoma yisiphi isivinini se-bit, ingagcina ngaphezulu kwama-channels amabili ngokunembile, futhi ihlala ifaka ukulibazisa okuncane kwe-encoder.

Ibhokisi lemisindo ngaphakathi kwalo, hhayi i-audio ngokwayo. Lo mbhalo ongeziwe uhlala lapho ubude, umbiko wokufuna kanye nanoma yimiphi imininingwane ye-metadata ifomu lichaza khona, ngakho umdlali ungazi ukuthi i AIFF ihlala isikhathi esingakanani ngaphambi kokuqothula ifremu eyodwa endaweni yokuskena ihele lonke ukuze ufunde. Lokhu kusho futhi ukuthi ubukhulu abukwazi ukuxazulula okungaphakathi: amabhokisi amaningi anjalo avunyelwe ukuphatha okungaphezu kwehlobo elinye lomsindo, ngakho amafayela amabili AIFF angasebenza ngendlela ehlukile ngenkathi ebona ngokufana ngaphandle. I-AIFF igcina i-PCM engacindezelwanga enkulu-endian — i-Apple-side elinganayo ne-WAV, nge-bit-for-bit fidelity efanayo.

Kulokhu kuphela ukuthi ukukopela kudlulele. MP3 okuqokwa kusuka ku-diski kwacindezelwa nganoma yisiphi isivinini se-bit esibekwe yi-ripper eminyakeni edlule, futhi lokho kuyi-top of the list kunoma yini esuka phansi - ukushintshana akukwazi ukubuyisela lokho okuqokwa kukhuphuke. Uma ama-diski akhona ethekwini, ukushintshana kabusha kufomethi engalahleki nokukopela kusuka lapho kunikeza imiphumela engcono kunanoma iyiphi i-conversion yefayela elikhona. MP3 yi MPEG-1 Audio Layer III, eqediwe ngo-1993, futhi ikhona ifomethi yomsindo ekwazi ukuconywa ngokugcwele.

Ngokuvamile akunjalo. MP3 i-decoded yinoma yini, kufaka phakathi iyunithi yemoto kanye nabadlali abadala; AIFF idinga isofthiwe eyazi i-codec, esebenzisa ihardware ehlukile. Uma indawo esiya kuyo imoto ye-stereo noma umdlali ophathekayo, lokhu kuyisinqumo esiqinile sokuhlala ku MP3. I-AIFF ikhulu njenge-WAV futhi inezixhaso ezibi ngaphandle kwe-Apple world, ngakho-ke iyisinqumo esibi sokusakaza.

Yebo, ngaphandle kwezimo ezifanele ukukhathazeka ngazo. Ulwazi olucacisiwe luyiqiniso, wonke umuntu angafaka umbhalo-mbhalo noma umbhalo-mbhalo oguquliwe ngaphandle kokubuza noma ukukhokha, futhi akukho muntu ongashintsha la mazwi ngemuva - ngakho-ke kuvela ku-open-source tooling, kuma-engine wemidlalo nakwezinye izindawo lapho i-license negotiation ibulala iphrojekthi. Ukushintshana isuka kuyo akuyibuyisela emuva lokho; amafayela akhona ahlala ngokugcwele njenge-useable njengoba bekhona.

I-Library yomuntu siqu, yebo; noma yini oyenzayo oyisabalalisa omunye umuntu, cabanga kathathu. AIFF iphumelela ngokukhululekile ngaphandle kokuvala - konke okudlala ngalo namuhla kuzoqhubeka nokudlala ngalo - kodwa amakhodi amasha namadivayisi amasha aqhubeka nokungajwayelekile kokufaka, okuzokwenza umsebenzi ofanayo. Uma ifayela lidinga ukuvulwa kuphela kuma-machines akho, kulungile. Uma lidinga ukuvulwa ku-device ethengiswe eminyakeni emihlanu, khetha enye entsha.

Ukuthunyelwa okungaziwa kuvunyelwe ngokuzenzakalela; ama-akhawunti abhalisiwe amahhala athola umkhawulo ophezulu, futhi ama-akhawunti we-Pro angeke abe ne-limit yefayela ngalinye. Umlando wesiphequluli uvame ukuba ngumkhawulo osebenzayo ngaphambi kokuba umkhawulo wethu we-server-side uqale.

Yebo. Thola noma khetha amafayela amaningi we-MP3 ku-upload eyodwa — umguquli usebenza ngazo ngokufanayo futhi ubuyisela i-ZIP yemiphumela ye-AIFF. Akunasidingo sokuphinda isikhashana sokufaka ihele ngalinye.
