Ukuthola i-CLI: Kusuka ku-wma uye kwi-mp3 ngezinyathelo ezi-2

Sanibonani kubo bonke abanonya nabathandi bezindawo I-GNU / Linux ukuthi njengami, sichitha usuku sizama ukwenza into efanayo eyenziwa abanye abantu kwezinye izinhlelo, okungadingeki ukuthi kube njalo Windows. Kuvele ukuthi ngithole iCD yakamuva ye U-X-Alfonso futhi ngaphambi kwenani elikhulu lama-geek laphaya futhi angazi, kuvumelekile ukucacisa ukuthi le CD bakunikela emanyuvesi kodwa kuhle kulokho obekukhona.

Wonke amathrekhi akwi-CD angenile I-WMA (IWindows Media Audio ... okungenani ngicabanga ukuthi kumele kube yisifinyezo salezo zinto) futhi ngokuvamile sine-guataca (indlebe) ivumelaniswe nefomethi MP3, ngakho-ke nginqume ukuthola ukuthi ngabe ikhona yini indlela, ngaphandle kokuwela kwifilosofi yesoftware ephathelene nokufaka izicelo zento ethile uhlelo lwethu olukwaziyo ukuyenza yodwa, ukufeza okufanayo futhi ubheke ukuthi kwenzeka kanjani ... uhlelo lwami (I-Debian 6.0 ne-LXDE)  Bengivele ngilungele ukukwenza, bengingazi nje ...

Ake sibone ukuthi ngiyazichaza yini, isidlali sevidiyo engisithandayo Umdlali. Enye into esiyidingayo ithuluzi lekhonsoli elibizwa blade kepha angazi noma kungokwami Debian kepha lapho ngaya ukuyifaka…. voila yayivele ifakiwe ngakho-ke angazi noma ngabe lokhu kuzenzakalelayo noma cha. Manje kuyaqhubeka, uma sebenakho vele Umdlali y blade ke ake siye endleleni yokukwenza, uma kunalokho ungenazo lezi zinhlelo zokusebenza kahle…. Ulindeleni ukuwafaka? vula ikhonsoli njengezimpande nohlobo (uthatha ukuthi usebenzisa iDebian noma okunye kokunye okuvela kukho):

apt-get install mplayer lame

Silungile, sesivele sinazo izinhlelo zokusebenza esizidingayo ezifakiwe ohlelweni lwethu, yize njengoba sengivele ngishilo ukuthi ezinye sezivele zizilethe ngokwakhona ukuze imilingo iqale:

Ake sicabange ukuthi sinefolda lapho amafayela we-WMA esifuna ukuwaguqula ekhona, ngikwenze lokhu esivivinyweni ngakho kukhonsoli sizobona into enjengale:

[ikhodi] neji @ Maq2: ~ / Desktop / wmatomp3 $ ls
4.wma
[/ ikhodi]

Uhlelo lweLame lusivumela ukuthi siguqule ifayela le-WAV libe yifomethi ye-MP3 kepha njengoba esinakho kuyifayela lohlobo lwe-WMA lapho sizosebenzisa iMplayer ukuyiguqulela ku-WAV ngokulandelayo:

[ikhodi] neji @ Maq2: ~ / Desktop / wmatomp3 $ mplayer 4.wma -ao pcm
I-MPlayer SVN-r31918 (C) 2000-2010 MPlayer Ithimba
Ayikwazi ukuvula i-joystick device / dev / input / js0: Alikho lelo fayela noma umkhombandlela
Ayikwazi ukufaka i-joystick yokufaka
mplayer: ayikwazanga ukuxhuma kusokhethi
mplayer: Alikho lelo fayela noma umkhombandlela
Yehlulekile ukuvula ukusekelwa kwe-LIRC. Ngeke ukwazi ukusebenzisa irimothi yakho.

Ukudlala i-4.wma.

Ungakhathazeki uma ifayili elibizwa nge «audiokuhle.wav»Ngaphandle kwezilinganiso, lelo yifayela eliguqulwe ngu umdlali manje sizoyisebenzisa nolunye uhlelo ukuyiguqula ibe yifomethi ye-MP3:

[ikhodi] neji @ Maq2: ~ / Desktop / wmatomp3 $ lame –r3mix audiodump.wav 4.mp3

Izici ze-CPU: I-MMX (i-ASM isetshenzisiwe), i-SSE (i-ASM isetshenzisiwe), i-SSE2
Usebenzisa isihlungi se-polyphase lowpass, ibhendi yokuguqula: 17960 Hz - 18494 Hz
Ukufaka ikhodi audiodump.wav kuya ku-4.mp3
Ukufaka ikhodi njenge-44.1 kHz j-stereo MPEG-1 Layer III VBR (q = 3)

Ilungile…. imiyalo emibili kuphela futhi sesivele siguqule ifayela lisuka ku-WMA laya ku-MP2. Ngiyazi ukuthi kwabaningi akumnandi kakhulu ukusebenzisa imiyalo eminingi kodwa ungahlala wenza iSkripthi isebenze futhi isebenze ngokufanayo kufolda yonke yamafayela.

Okwamanje ngiyaqeda ngalokhu, uyazi, yiba muhle futhi ungalahli intshisekelo yokufunda nokuningi okubaluleke kakhulu: ngemuva kokuthi ufunde okuthile, noma ngabe kubonakala kungabalulekile kangakanani, ungayeki ukuwabelana nabanye njengoba ngenzile kuwe nje .
