Kodi ndingasinthire bwanji WAV audio kupita ku AMR popanda kuwononga mtundu?

Kutsitsa fayilo ya WAV ndipo wosintha amasankha kulumikizana kwa AMR codec / bitrate komwe kumagwirizana ndi fayilo ya chiyambi. AMR yopanda kusowa (WAV / FLAC / ALAC) imasunga zonse mwatsatanetsatane; AMR yowonongeka (MP3 / AAC / OGG / Opus) imayikidwa ku 192 kbps yomwe ndi yosawoneka bwino kwa pafupifupi zonse zomwe zili ndi nyimbo. WAV nthawi zambiri amasunga raw uncompressed PCM - aliyense sample anatenga moyenera, pa zimene bit kuwala ndi sampling rate anathawa. AMR ndi narrowband mawu codec kuyendetsa pakati pa 4.75 ndi 12.2 kbps, modeling munthu woimba m'mimba kuposa wonse audio spectrum.

Kodi ndibwino bwanji kuti ndichepetse kusinthidwa kwa WAV ku AMR?

Ena, ndipo ndi nthawi yayitali - ichi ndi chiwongola dzanja chomwe chimabweretsa zambiri. WAV imakhala ndi zonse zomwe zimapezeka; AMR imachotsa zomwe psychoacoustic model imayembekezera kuti simudzawona. Pa 192 kbps ndi pamwambapa kuti kuyembekezera ndi kokwanira kuti zikhale zowoneka bwino pazinthu zambiri ndi zida zambiri. Tengani WAV monga mtsogoleri wanu, chifukwa simungathe kubwerera ku AMR.

Kodi chimachitika ndi ma audio ambiri a multichannel pamene amasintha WAV ku AMR?

Idzaikidwa pansi pa stereo, chifukwa AMR siyimakhala ndi njira yogwiritsira ntchito ma channel ambiri. Kulowetsa kumagwiritsa ntchito ma coefficients ovomerezeka kuti ma channel apakati azikhala owoneka bwino ndipo ma surrounds amaphatikizidwa pamalingaliro otsika. Chomwecho chilichonse chomwe chimadalirika pa malo osiyanasiyana a ma channel chimapita pamene izi zikuchitika. AMR amawononga nyimbo: yake 8 kHz bandwidth amachotsa zonse pamwamba foni ma frequencies, ndi palibe ndalama ya re-encoding amabweretsa izo kumbuyo.

N’chifukwa chiyani nyimbo zimawoneka zoipa kwambiri pa chikhulupiriro?

Chifukwa chimodzi mwazigawo zake ndi codec ya mawu kuposa codec ya nyimbo. Imakhala ndi maonekedwe a munthu woimba ndipo imachotsa chilichonse m’mbali mwa bandwidth ya foni, chomwe ndi choyenera kwa mawu olemba mawu komanso chowononga kwa chilichonse chomwe chili ndi zida. Kusintha kuchokera pa izo sikungabwezeretse ma frequencies osakhudzidwa — iwo sanali kusinthidwa pamalo oyamba. WAV ndi lalikulu - pafupifupi 10 MB pa stereo mphindi pa CD quality - ndi classic mtundu ali 4 GB chipinda ndi palibe malo kwa ma tag bwino.

Kodi kujambula kopitilira muyeso WAV kutsitsa bwino?

Maakaunti aulere amafika pa 100 MB pa fayilo, ndipo WAV amayenda mpaka 10 MB pa mphindi mu stereo chifukwa palibe chomwe chimakonzedwa - chilichonse chimasunga pa kutalika kwa kutalika. Mphindi makumi asanu ndi khumi ndi zisanu ndi zitatu zapitazo. Premium imatulutsa chingwe chokwanira, ndipo mtunduwo uli ndi 4 GB yokha pamwamba pa zomwe, chifukwa chake maulendo opitilira nthawi yayitali amafika ogawidwa m'magawo owerengeka; kutsitsa nawo limodzi ndipo amachitidwa ngati ntchito imodzi.

Kodi ndi bitrate iti yomwe fayilo ya AMR imatha?

Default 192 kbps for lossy AMR; pass-through for lossless AMR. Override to 320 kbps if you want maximum lossy fidelity, 128 kbps for size-restricted podcast distribution, or 96 kbps for voice-only sources where the smaller file matters more than studio detail.

Kodi kuchoka ku WAV kupita ku AMR kumachepetsa kwambiri mtundu wanga wa audio?

Ngati WAV ndi yowonongeka (MP3, AAC) ndi AMR ndi yopanda kusowa (WAV, FLAC), AMR si yabwino kuposa WAV - simungathe kubwezeretsa zambiri zomwe zatulutsidwa ndi WAV codec yowonongeka. Ngati WAV ndi yopanda kusowa ndi AMR ndi yopanda kusowa, yembekezerani kuti AMR encoder ibwezeretse; pa 192 kbps kuwonongeka kumakhala kosadziwika kwa nkhope zambiri.

Kodi wosintha WAV kupita ku AMR amasunga ID3 / metadata tags?

Ndikoyenera - dzina, woimba, album, chaka, mndandanda wa nyimbo, album art, BPM, kusewera-kupeza kumawerengedwa kuchokera ku WAV chomera ndi kulemba m'madera ofanana pa AMR chomera. ID3v2 (MP3), Vorbis maganizo (OGG, FLAC), MP4 atoms (AAC, M4A), RIFF INFO (WAV), iXML chidutswa zonse map cleanly. AMR ndi Adaptive Multi-Rate, mawu codec 3GPP standardized kwa GSM mawu kulankhula ndi mafoni mawu olemba.

Kodi ndingasinthire ma WAV ambiri a AMR?

Yes — chotsani fayilo ya WAV ndipo tidzazipanga mofanana. Premium ili ndi ogwira ntchito ambiri mofanana ndi malire a fayilo, kotero fayilo ya 500 imatha m'maola ochepa kuposa maola asanu. Mtundu wa fayilo umasungidwa mu ZIP yotulutsidwa.

Kodi AMR idzakhala ndi kuchuluka kwa sampling yomweyo ngati WAV?

Mwa default ndi yemweyo (48 kHz WAV imatulutsa 48 kHz AMR, 44.1 kHz WAV imatulutsa 44.1 kHz AMR). Kuti mukwaniritse zofunikira — monga kuchepetsa 96 kHz studio masters mpaka 44.1 kHz AMR polemba CD, kapena kuwonjezera 22 kHz voicemail mpaka 44.1 kHz AMR — mndandanda wolowetsa wa sampling-rate umagwiritsa ntchito kuwonjezera kwa SOX-style.

Kodi ndingasinthire kuwala kwa mawu m'mawindo a WAV mpaka AMR?

Ndiyo — kusankha kwa loudness-normalize kumagwiritsa ntchito ITU-R BS.1770 / EBU R128 ku AMR output, kulenga -14 LUFS (streaming standard) kapena -16 LUFS (podcast standard) kapena malire apadera. Kuthandiza pamene mukusintha nyimbo ndi zigawo zosiyanasiyana za mastering kukhala imodzi AMR playlist.

Kodi AMR idzasewera pa stereo yagalimoto yanga / iPod / Sonos / wokamba nkhani wa Bluetooth?

MP3 imasewera padziko lonse lapansi pazinthu zonse zomwe zidapangidwa mzaka zapitazi 20. AAC imasewera pa Apple, ambiri a Android, Sonos, ndi ma stereo amakono agalimoto. FLAC imasewera pa Sonos ndi Android yaposachedwa, osati bwino pa iPods oyambirira. WAV imasewera pa chilichonse koma fayilo ndi yayikulu. Kuwonekera kwa chipangizocho chimasankha AMR codec yotetezeka kwa pulogalamu yomwe mumasankha. AMR amachititsa mawu kujambula absurdly ochepa - nthawi ya mawu amagwirizana mu megabytes angapo - ndipo ndi zimene ambiri mafonibe kujambula mafoni mu.

WAV

Mafayilo a WAV amasunga mawu mu mtundu wosasindikizidwa, zomwe zimapangitsa kuti CD ikhale yabwino kwambiri pa ntchito yaukadaulo yolankhula.

AMR

AMR (Adaptive Multi-Rate) ndi mtundu wamawu wokongoletsedwa kuti azitha kukopera mawu. Amagwiritsidwa ntchito kwambiri m'mafoni a m'manja pojambula mawu komanso kusewera.
