Kutsitsa fayilo ya MP3 ndipo wosintha amasankha kulumikizana kwa MP2 codec / bitrate komwe kumagwirizana ndi fayilo ya chiyambi. MP2 yopanda kusowa (WAV / FLAC / ALAC) imasunga zonse mwatsatanetsatane; MP2 yowonongeka (MP3 / AAC / OGG / Opus) imayikidwa ku 192 kbps yomwe ndi yosawoneka bwino kwa pafupifupi zonse zomwe zili ndi nyimbo. MP3 ndi lossy: psychoacoustic model amachotsa ma frequencies kuti nkhope sizingayembekezere kuti adziwe, makamaka pa 128 mpaka 320 kbps. MP2 ndi lossy koma amagwiritsa ntchito zosatheka filterbank kuposa MP3, nthawi zambiri ntchito pa 192 mpaka 384 kbps.
Kodi kusinthira MP3 ku MP2 ndi gawo lachiwiri la kutsitsa kwa lossy?

Ndikukhulupirira kuti ndinu oyenera, ndipo ndibwino kuti mupange. Mafomu awiriwa ndi owonongeka, choncho MP2 encoder akuchita ntchito kuchokera ku audio yomwe yakhala ikuyenda mwa psychoacoustic pass, ndipo masankho ake oyamba amapanga gawo loyamba. Pa 192 kbps kapena pamwambapa, zotsatirazi ndizosawoneka bwino kwa ambiri owerenga. Ngati muli ndi master yopanda kuwonongeka, kulemba koyamba kwa MP2 kuchokera ku yomwe imalepheretsa kupitanso koyamba.

Siyimagwira ntchito. MP3 imathamanga ndi metadata block yoyenera, koma MP2 siyimagwira ntchito yoyenera ya woimba, album, track number kapena cover art, kotero ma tag amatulutsidwa mosasokonezeka. Tengani MP3 ngati kopita kosindikizidwa, kapena kulembanso kosindikizidwa pambuyo pake ndi chida monga Mp3tag kapena MusicBrainz Picard. MP2 amafuna kwambiri bitrate kuposa MP3 kapena AAC kwa ubwino wofanana ndi sizikudziwika kwa ambiri wosuta mapulogalamu.
Kodi ndi bitrate iti yomwe fayilo ya MP2 imatha?
+
Default 192 kbps for lossy MP2; pass-through for lossless MP2. 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 MP3 kupita ku MP2 kumachepetsa kwambiri mtundu wanga wa audio?
+
Ngati MP3 ndi yowonongeka (MP3, AAC) ndi MP2 ndi yopanda kusowa (WAV, FLAC), MP2 si yabwino kuposa MP3 - simungathe kubwezeretsa zambiri zomwe zatulutsidwa ndi MP3 codec yowonongeka. Ngati MP3 ndi yopanda kusowa ndi MP2 ndi yopanda kusowa, yembekezerani kuti MP2 encoder ibwezeretse; pa 192 kbps kuwonongeka kumakhala kosadziwika kwa nkhope zambiri.
Ndikoyenera - dzina, woimba, album, chaka, mndandanda wa nyimbo, album art, BPM, kusewera-kupeza kumawerengedwa kuchokera ku MP3 chomera ndi kulemba m'madera ofanana pa MP2 chomera. ID3v2 (MP3), Vorbis maganizo (OGG, FLAC), MP4 atoms (AAC, M4A), RIFF INFO (WAV), iXML chidutswa zonse map cleanly. MP2 ndi MPEG-1 Audio Layer II, latsopano la MP3 ndi MP3 ndi mtundu wa audio standard kwa DVB ndi DAB kufalitsa.
Kodi ndingasinthire ma MP3 ambiri a MP2?
+
Yes — chotsani fayilo ya MP3 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 MP2 idzakhala ndi kuchuluka kwa sampling yomweyo ngati MP3?
+
Mwa default ndi yemweyo (48 kHz MP3 imatulutsa 48 kHz MP2, 44.1 kHz MP3 imatulutsa 44.1 kHz MP2). Kuti mukwaniritse zofunikira — monga kuchepetsa 96 kHz studio masters mpaka 44.1 kHz MP2 polemba CD, kapena kuwonjezera 22 kHz voicemail mpaka 44.1 kHz MP2 — mndandanda wolowetsa wa sampling-rate umagwiritsa ntchito kuwonjezera kwa SOX-style.
Kodi ndingasinthire kuwala kwa mawu m'mawindo a MP3 mpaka MP2?
+
Ndiyo — kusankha kwa loudness-normalize kumagwiritsa ntchito ITU-R BS.1770 / EBU R128 ku MP2 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 MP2 playlist.
Kodi MP2 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 MP2 codec yotetezeka kwa pulogalamu yomwe mumasankha. MP2 ndi kwambiri yolimba kuti bit zoipa ndi yosavuta ku decode, amene ndi chifukwa chake kufalitsa masamba anasiya pa izo nthawi yaitali pambuyo MP3 anafika.
Kodi fayilo yanga MP3 ndi yachikhalidwe panthawi yosintha?
