AMR ukuba WAV Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni eyenza i-AMR ukuya kwi-WAV iguquli sesandi?

AMR sele ilahlekile, ngoko ukuguqula kwi WAV igcina isandi esisekho ngaphandle kokunyuka ezantsi, kodwa ayikwazi ukubuyisela inkcukacha ezilahlekileyo kwikhowudi yokuqala. WAV ilungile ukuba ucwangcisa ukuhlela nokugcina kwakhona ngaphandle kokudibanisa ii-artifacts zokucinezela.

Ingaba inqanaba lesampuli kunye nobeko lwesiqhagamshelanisi ziya kugcinwa?

Ngokungagqibekanga ewe — i-stereo ihlala i-stereo, i-sample rate emiselweyo (44.1 kHz, 48 kHz, njl.njl.) idluliselwa kwi-WAV output.

Ingaba ifayili ye WAV izakuba mkhulu kakhulu kunesiqulathi seefayili se AMR?

Ewe - isandi esingalahlekiyo sihlala singaphezulu nge-5-10x kunesandi esilahlekileyo kwinqanaba lomgangatho ofanayo. Phanda i ~10 MB ngomzuzu ngamnye kwi-WAV versus ~1 MB ngomzuzu ngamnye kwi-high-bitrate AMR.

Ingaba i-WAV iya kuba banzi kune-AMR?

Ewe — iziqulatho ezingalahleki zigcina i-byte nganye. Lindela ukuba i-WAV ibe yi-3-8x ubungakanani be-AMR. Inyani kukuba akukho kufumana kwakhona umgangatho xa uhlela okanye uphinde ubhale kwakhona ikhowudi.

Ingaba ukutshintsha AMR ukuya ku WAV kunyusa umgangatho wesandi?

Hayi, kwaye ixabiso lokuba mnyama: akukho nto ingayenza. I AMR sele ishiye inkcukacha ngexesha lokushicilela kwayo, kwaye ukujikelezisa okuseleyo kwi WAV engalahliyo igcina ngokuchanekileyo oko - akukho ngaphezulu. Ifayile ifumana amaxesha amaninzi akhulu kwaye ithetha ngokufanayo. Iyaqhubeka intshukumo elungileyo phambi kohlela, kuba WAV ayizukongeza udidi lwesibini lwe artefacts xa urhweba ngaphandle. I-WAV yifomati efanelekileyo yohlela, ulawulo nokugcina, kuba ingaphinde ikhowudiwe nanini na ngaphandle kokudibanisa iindidi. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okungaphezulu kweefrequencies zefowuni, kwaye akukho xabiso lokucofa kwakhona liyibuyisela.

Yintoni na i-WAV ifayili?

Isiqulathi seefayili esinomsindo ngaphakathi kwayo, kunokuba umsindo ngokwawo. Lo maleko ongaphezulu yindawo apho ubude, isalathisi sokukhangela kunye ne metadata yefomati echazayo igcinwa khona, ngoko umdlali uyazi ukuba i WAV ihlala ixesha elingakanani phambi kokucoda iframe enye endaweni yokukhangela ifayile yonke ukufumanisa. Oku kuthetha ukuba unikezelo alusoloko lugqiba into engaphakathi: iziqulathi zeefayili ezininzi ezinjalo zivunyelwe ukuba zigcine ngaphezulu kwesinye isifo sesandi, oko kukuthi, iifayile ezimbini WAV zingaziphatha ngokuhlukileyo ngelixa zijonge ngaphaya. I-WAV igcina i-PCM engacinezelwanga emnyama - yonke isampuli igcinwa ngokuchanekileyo, nakweyiphi na ubunzulu be-bit kunye nesantya sesampuli esithathwe.

Ingaba kukho ilayisensi edityaniswe ne AMR?

Akukho nto ofuna ukuyicinga. I-codec iquka i-patent pools, kwaye ilayisensi ibekwe ngumthumeli we-decoder - ifowuni, umkhangeli zincwadi, inkqubo yokusebenza - ixesha elide phambi kokuba ifayile ifike kuwe. Yiyo loo nto ifomati ikho kuyo yonke indawo kwihardware, kwaye kutheni i royalty- free alternatives yakhiwa naphi na. Ayitshintshanga nto malunga nokutshintsha ifayile oyinayo, kwaye kumbuzo ophilayo kuphela ukuba uthumeli i-encoder ngokwakho.

Kutheni umculo uthetha ntoni xa uguqulwa?

Kuba enye icala liyi codec yokuthetha kune codec yengoma. Imodelisa umjelo wokuthetha womntu kwaye ishiya konke ngaphandle kwe bandwidth yefowuni, elungileyo kwimemo yokuthetha neyophazamisayo nantoni na enezixhobo kuyo. Ukutshintsha kude nayo akuyi kubuyisela uxinzelelo olulahlekileyo - akufuneki kubekho ukuvulwa kwindawo yokuqala.

Ingaba kukho umda wobungakanani befayili xa uguqula i-AMR ibe yi-WAV?

Ulayisho phezulu olungaziwayo luphelelwe lixesha ngokumiselweyo; i-akhawunti ebhalisiweyo ekhululekileyo ifumana umda ophezulu, kwaye i-akhawunti ye-Pro ayinalo umda wefayili nganye. Inkumbulo yesikhangeli sihlala siyimfuneko yothintelo ixesha elide phambi kokuba umda wethu we-server-side uqale.

Ndingaguqula iifayili ezininzi ze-AMR zibe yi-WAV ngaxeshanye?

Ewe. Nqumle okanye ukhethe iifayile ezininzi ze AMR kwifayili enye yokulayisha - umguquli uqhubekeka nazo ngokuthe tye kwaye ubuyisele i-ZIP yeziphumo ze WAV. Akukho mfuneko yokuphinda uqhubekeke inkqubo yefayili nganye.

Ithini into eyenza ukuba i-AMR yam ifile iguqulwe?

Iifayili ezilayishwe phezulu kunye ne-WAV iimveliso zicinywa ngokuzenzekelayo emva kwefestile efutshane yokugcina. Asiyi kujonga, sizonwabele, okanye siqeqeshe kwiifayili zomsebenzisi. Ikhonkco lokulayisha ezantsi ngokuthe ngqo limiselwe ixesha kwaye lidityaniswe kwintlanganiso yakho.

Ziziphi iinkqubo ezikwaziyo ukudlala ifayili ye WAV?

WAV idlala kumaqela amaninzi emidlalo, kwii-browser, kunye neelayibrari zemidiya. I-iTunes / i-Apple Music, i-VLC, i-Foobar2000, kunye neenkqubo zemidiya yefowuni ziphatha ngokuzimeleyo.
