Guqula amafayela womsindo we-AMR abe yi-MP3, OGG, njll.

I-AMR yifomethi yokucinana yomsindo elungiselelwe ukubhala ikhodi yenkulumo. Idume kakhulu kumaselula wesimanje.

I-AMR yamukelwe njengezinga lokufaka amakhodi lomsindo ngo- I-3gpp ngo-Okthoba 1998 futhi manje isetshenziswa kabanzi ku- GSM. Phatha ngamandla umkhawulokudonsa ngokukhetha kusuka kumanani entengo ahlukene ayisishiyagalombili.

Ama-bandwidths 12.2, 10.2, 7.95, 7.40, 6.70, 5.90, 5.15, no-4.75 kb / s asuselwa kumasampuli ayi-8000Hz anezinhlaka ezingama-20 millisecond (amasampula ayi-160 ngohlaka ngalunye).

Kunezinhlelo zokuguqula le fomethi ibe yifomethi yomsindo ejwayelekile (njenge MP3 o WAV); isibonelo, i-Mobile Media Center. Ukusetshenziswa kwalokhu kuyadingeka ngoba akubona bonke abadlali bemisindo ube nama-codecs ngokuzenzakalela adingekayo ukudlala amafayela afakwe ikhodi njenge-AMR.

Namuhla, ukuba nomakhalekhukhwini akufani nje nokushaya izingcingo; Okweminyaka embalwa, ukuba neyodwa yalezi zinsiza kusho nokuthi kungenzeka ukuthatha izithombe, ulalele umculo, ubuke amavidiyo, njll. Kwesinye isikhathi kuyenzeka ukuthi akuwona wonke amafomethi wemultimedia asekelwa ngamakhompiyutha, ngakho-ke kuyadingeka ukuthi sibheke okulingana nakho ngefomethi esingayisebenzisa noma okungcono sibe nethuluzi elisisiza ukuthi siguqule ifomethi eyodwa yemultimedia kwenye.

I-Ffmpeg, umtapo wolwazi osetshenziswa kakhulu ku-Linux ukuguqula amafayela wemultimedia, uyekile ukuxhasa i-libamr ngenxa yezinkinga zokulayisense futhi ufake ukwesekwa kwe-libopencore-amr. Noma kunjalo, Iphakheji ye-ffmpeg efakwe ku-Ubuntu Karmic ayisekeli i-AMR.

Ngalesi sizathu, kufanele sisebenzise olunye uhlelo (empeleni i-GUI ye-ffmpeg ngosizo lwe-AMR), olubizwa nge-Mobile Media Center.

I-Mobile Media Converter uhlelo lokusebenza lwamahhala oluvumela, njengoba kushiwo ngaphambili, ukuguqula amafomethi e-multimedia ahlukahlukene. Isibonelo: 3gp to mp3, mp3 to amr, etc. Futhi uma lokho bekunganele, ibuye ilande amavidiyo we-YouTube ngendlela oyithandayo, ukusebenza kwesicelo kanje:

1. Landa i-Mobile Media Center kusuka ku- lapha.
2. Faka iphakheji ye-.DEB.
3. Uma une-AMD64, vula ukuphela, iya kufolda lapho kutholakala khona i-.DEB bese usebenza:

I-sudo dpkg -i --force-konke mmc_1.5.0_i386.deb

Uma usuqedile, iya kokuthi Izicelo> Umsindo neVidiyo> Isiguquli Semidiya Esimatheni. Ngemuva kwalokho,

1. Faka ifayela ofuna ukuliguqula ngokuchofoza ku "+"
2. Khetha ifomethi yokukhipha, ikhwalithi, chofoza ku- "Guqula!" futhi ngomumo.

Njengoba ukwazi ukubona, akuvumeli kuphela ukuguqula amafayela we-AMR ajabulisayo kepha futhi namanye amaningi, okwenza kube inketho enamandla yokubheka.
