AIFF vs WAV
AIFF thiab WAV yog ob lub suab ntaub ntawv tsim tawm hauv xyoo 1990 thiab tseem siv tau. Ob hom ntaub ntawv qhia tib lub hauv paus chiv keeb; lawv tau muab los ntawm IFF cov ntaub ntawv hom. Ob hom ntaub ntawv yog thawj tiam ntawm cov ntaub ntawv siv hauv kev ua suab / kho software vim yog cov ntaub ntawv zoo.
AIFF yog dab tsi?
AIFF lossis Audio Interchange File Format yog hom ntaub ntawv suab tsim los ntawm Apple Computer rau Personal Computers xyoo 1988 raws li Kev Sib Hloov Cov Ntaub Ntawv (IFF) tsim los ntawm Electronic Arts / Amiga systems. AIFF yog qhov loj-endian derivation los ntawm IFF thiab siv dav hauv Mac OS.
AIFF siv chunks los khaws cov ntaub ntawv, thiab txhua qhov chunk raug txheeb xyuas los ntawm chunk ID. Common Chunk thiab Suab chunk yog qhov yuav tsum tau chunks. Tsis tas li, Marker, Comment, Name, Author, Copyright, Instrument, Annotation, Audio Recording, MIDI and Application chunks are used when applicable.
AIFF yog cov ntaub ntawv tsis zoo uas siv cov kev hloov pauv ntawm cov mem tes tsis sib haum (PCM) thiab khaws cov ntaub ntawv suab zoo. Yog li ntawd, AIFF yog siv nyob rau hauv zoo suab thiab video editing raws li Mac systems. Txij li nws tsis yog ib hom ntawv compressed, qhov loj ntawm cov ntaub ntawv suab zoo li loj dua cov ntaub ntawv compressed xws li mp3. AIFF muaj qhov sib txawv compressed siv sib txawv compression codecs uas yog hu ua AIFF-C thiab muaj qhov txuas ntxiv aifc.
WAV yog dab tsi?
WAV lossis Waveform Audio File Format yog ib hom ntaub ntawv tsim los ntawm Microsoft thiab IBM rau PCs, thiab nws yog qhov muab los ntawm Microsoft Resource Interchange File Format (RIFF). Inheriting los ntawm IFF, hom no kuj khaws cov suab raws li cov ntaub ntawv chunks. Ib daim ntawv WAV feem ntau yog RIFF cov ntaub ntawv nrog ib qho "WAV" chunk thiab muaj ob lub chunks hu ua fmt thiab cov ntaub ntawv. WAV yog cov hom ntaub ntawv tseem ceeb siv hauv windows raws li software rau lub suab zoo.
WAV yog hom ntawv tsis muaj ntaub ntawv; yog li ntawd tsis muaj compression ua tiav thaum lub sij hawm encoding ntawm cov ntaub ntawv kwj hauv linear mem tes code modulation hom. Raw thiab uncompressed suab ntaub ntawv feem ntau generated nyob rau hauv WAV hom nyob rau hauv lub qhov rais. Nws tuaj yeem hloov kho thiab kho tau yooj yim, thiab cov kws tshaj lij nyiam WAV kom zoo dua. Txawm hais tias nws qhov kev siv tseem ceeb li cov thawv ntim cov ntaub ntawv uas tsis tau ntim, WAV kuj tuaj yeem tuav lub suab compressed, uas yog compressed los ntawm Windows Audio Compression Manager.
Vim vim tsis muaj cov ntaub ntawv encoding, WAV cov ntaub ntawv zoo li loj; yog li ntawd, tsis yog cov ntaub ntawv nrov rau kev hloov hauv internet. Txawm li cas los xij, lawv tseem nrov vim nws qhov yooj yim thiab zoo.
Qhov txawv ntawm AIFF thiab WAV yog dab tsi?
• WAV yog tsim los ntawm Microsoft, whereas AIFF yog tsim los ntawm Apple.
• AIFF yog Apple sib npaug ntawm WAV thiab ob hom ntaub ntawv raug lees paub los ntawm ob lub tshuab. (Qhov tseeb, cov ntaub ntawv txuas ntxiv tuaj yeem hloov pauv tau ntau lub sijhawm)
• Ob WAV thiab AIFF muaj tib lub hauv paus chiv keeb thiab sib qhia tib cov ntaub ntawv raws li IFF.
• Ob leeg siv lossless encoding hauv uncompressed PCM.
