MP3 ilaa M4R Su'aalaha Badiya La Weydiiyo Ee Ku Saabsan Beddelka
Sidee baan u beddeli karaa MP3 audio ilaa M4R iyadoon la lumin tayada?
+
Soo deji faylka MP3 oo soo beddelaha wuxuu doortaa isku-dhafka codec / bitrate ee M4R oo la mid ah asalka. M4R (WAV / FLAC / ALAC) oo aan waxba ka jirin ayaa si sax ah u ilaalinaya tusaale kasta; M4R (MP3 / AAC / OGG / Opus) oo aan waxba ka jirin ilaa 192 kbps oo cad oo u eg dhammaan waxyaabaha muusikada. MP3 waa lossy: a psychoacoustic qaabka ka saaro frekuency dhegta waa in aan la filayn in la ogaado, caadi ahaan 128 ilaa 320 kbps. Payload waa AAC, caadi ahaan ku koobnaa 40 ilbiriqsi, taas oo ah codka ugu dheer ee iOS aqbali doonaa.
Ma aha in lagu beddelo MP3 ilaa M4R wareegga labaad ee isku dhafka khasaaraha?
+
Haa, waana wax ku habboon qorsheynta. Labada qaababba waa waxyeello, sidaa darteed M4R codsi-qorayaasha ayaa ka shaqeeya codka oo horeyba u maraya hal xagal psychoacoustic ah, iyo go'aamadeeda gaarka ah waxay isku daraan xulashada koowaad. 192 kbps ama ka sarreeya natiijada ayaa weli u muuqata mid cad oo u muuqda mid ka mid ah dhagaystayaasha badan. Haddii aad leedahay madaxa waxyeellada leh meel kasta, codsiga M4R kaas oo ka hortagaya in la qaado laba jeer oo dhan.
Fadlan xusuuso in faylka M4R uu ku dhammaado bitrate?
+
Default 192 kbps loo baahan yahay loo baahan yahay M4R; pass-through loo baahan yahay loo baahan yahay M4R. Ku dar 320 kbps haddii aad rabto in aad ugu badan oo loo baahan yahay loo baahan yahay, 128 kbps si aad u qaybiso podcast-ka, ama 96 kbps si aad u hesho cod-keliya oo keliya oo ah meesha faylka yar yahay wax ka badan faahfaahinta studio.
Ma ka dhigi kartaa MP3 ilaa M4R mid ka hooseeya tayada maqalka?
+
Haddii MP3 ay tahay mid khasaartay (MP3, AAC) iyo M4R waa mid aan khasaarin (WAV, FLAC), M4R maahan mid ka fiican MP3 - ma awoodi kartid inaad soo ceshato macluumaadka horeyba loogu tirtiro codec-ka MP3. Haddii MP3 ay tahay mid aan khasaarin iyo M4R ay tahay mid khasaartay, ka fiiri M4R encoder si aad u soo celiso; at 192 kbps khasaaraha waa mid aan la arki karin dhegaha badan.
Ma MP3 ilaa M4R ayaa ku beddelaya ID3 / metadata tags?
+
Haa - magaca, muusig, album, sanadka, lambarka raadinta, sawirka album, BPM, soo noqnoqoshada-gacan ayaa laga akhrin karaa MP3 baakadaha oo lagu qoray meelaha la midka ah ee M4R baakadaha. ID3v2 (MP3), faallooyinka Vorbis (OGG, FLAC), atoms MP4 (AAC, M4A), RIFF INFO (WAV), iXML chunks dhammaan khariidadda si nadiif ah. M4R waa iPhone ringtone - a caadi ah AAC file in MP4 container la kordhinta la beddelay si iTunes files sida codka.
Ma ku beddeli karaa boqolaal fayl oo MP3 ah M4R?
+
Haa - ku rid faylka MP3 faylasha oo aan u gudbinno si isku mid ah. Premium waxay leedahay shaqaalaha isku midka ah iyo ma laha xaddiga faylka, sidaa darteed 500-file batch wuxuu ku dhammaadaa daqiiqado ka badan alaabtii daqiiqado.
M4R ma ku hayn doontaa tirada tusaale ee MP3?
+
By default haa (a 48 kHz MP3 soo saartaa 48 kHz M4R, a 44.1 kHz MP3 soo saartaa 44.1 kHz M4R). Ujeedada gaar ah ee la jaanqaadista - tusaale ahaan, hoos u dhigista 96 kHz studio masters ilaa 44.1 kHz M4R CD-da lagu qoro, ama kor u qaadista 22 kHz fariimaha codka ilaa 44.1 kHz M4R - tusaale-ka-dhimista hoos u dhaca ayaa ku habboon tayada sare ee SOX-style resampling.
Ma ku hagaajin karaa codka MP3 ilaa M4R?
+
Haa - ikhtiyaarka loodness-normalize wuxuu ku habboon yahay ITU-R BS.1770 / EBU R128 caadiga ah ee M4R soosaarka, oo ku lug leh -14 LUFS (sharciga qulqulka) ama -16 LUFS (sharciga podcast) ama qiime gaarka ah. Faa'iido leh marka la barbardhigo raadadka la isku beddelayo oo leh heerar kala duwan oo heerar ah oo ah M4R playlist.
Ma M4R ayaa ku ciyaari doona gaarigayga stereo / iPod / Sonos / Bluetooth speaker?
+
MP3 plays universally on every device made in the last 20 years. AAC plays on Apple, most Android, Sonos, and modern car stereos. FLAC plays on Sonos and recent Android, less well on older iPods. WAV plays on everything but the file is huge. The device-target dropdown picks a safe M4R codec for the platform you specify. M4R hoos u dhac ku socda iOS Dhaqdhaqaaqa liiska via Finder ama iTunes la aan wax ka badan processing. M4R waa Apple-keliya iyo dhererka-la xaddiday; wax kasta oo ka badan 40 ilbiriqsi waa si qaylo leh loo diiday telefoonka.
Faylkayga MP3 ma gaarbaa marka la beddelayo?
+
Haa — faylasha la soo dejiyey MP3 waxaa lagu dhaqaajiya shaqaalaha kala duwan oo la tirtiraa daqiiqado gudahood. Aan marnaba ciyaarin, kaydin, ama qaybin waxyaabaha maqalka ah. Wabiga wuxuu ku socdaa qalabka aan xakamaynayno dhammaadka-dhamaadka; adeegyada dhinac saddexaad ma helaan faylkaaga.
Maxaa ka dhigaya fayl M4R inuu ka weyn yahay ama ka yara yahay asalka MP3?
+
Haddii aad maqasho isbeddel heer ah, ciyaaryahankaaga audio ama maktabadda warbaahinta ayaa laga yaabaa inay ku soo bandhigto ReplayGain ama caadi ahaanta per-track ee ciyaarta - ka saar oo M4R wuxuu u eg yahay bit-ka MP3 (si loo yareeyo) ama si aad u aragto mid ka mid ah (si loo yareeyo midabkeedu).
Faylasha MP3 waxay isticmaalaan cadaadis lumis ah si loo yareeyo cabbirka faylka iyadoo la ilaalinayo tayada codka ee la aqbali karo ee dhagaystayaasha badankood.
