Beddel MP3 ilaa AMR

Haa, waana wax ku habboon qorsheynta. Labada qaababba waa waxyeello, sidaa darteed AMR 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 AMR kaas oo ka hortagaya in la isku daro. MP3 waa lossy: a psychoacoustic qaabka ka saaro frekuency dhegta waa in aan la filayn in la ogaado, caadi ahaan 128 ilaa 320 kbps. AMR waa codsi codka narrowband socda u dhexeeya 4.75 iyo 12.2 kbps, qaabeynta wadnaha codka aadanaha ka badan sida ay u kala duwanaansho audio buuxa.

Ma jiro. MP3 wuxuu ku jiraa blokada metadata saxda ah, laakiin AMR ma laha meel caadi ah oo loogu talagalay muusig, album, lambarka raadinta ama sawirka daabacaadda, sidaa darteed tagga ayaa la jaray oo aan la jabin. Ilaalinta MP3 sida koontada la daabacay, ama dib u soo celi ka dib qalab sida Mp3tag ama MusicBrainz Picard. AMR music burburin: 8 kHz bandwidth ka saaraa wax kasta oo kor ku xusan frekuency telefoonka, iyo wax lacag ah oo dib-codsiinta soo celin.

Waayo, dhinac ka mid ah waa codsi codsi hadalka ka badan codsi codsi muusig. Waxay qaabeeyaa habka codka aadanaha oo ka saaro wax kasta oo ka baxsan bandwidth telefoonka, taas oo ah mid wanaagsan oo codka iyo waxyeello u ah wax kasta oo ay la jiraan qalabka ku jira. MP3 waa technically outclassed by AAC iyo Opus at bitrate kasta, ma kaydin karo in ka badan laba kanaal oo faa'iido leh, iyo waliba ku daray dib u dhac coder yar.

Default waa 192 kbps loo baahan yahay AMR; pass-through loo baahan yahay AMR. Ku dar 320 kbps audiophile ama 64-96 kbps loogu talagalay buugaagta maqalka ah ee hadalka (caddeysan codka, qaybinta faahfaahinta faahfaahinta).

Haddii MP3 ay tahay mid khasaartay iyo AMR ay tahay mid aan khasaarin (tusaale ahaan MP3 → WAV), faylka AMR ma aha mid ka fiican MP3 — ma awoodi kartid inaad soo ceshato macluumaadka horeyba loo tuuray. Haddii MP3 ay tahay mid khasaartay iyo AMR ay tahay mid khasaartay, ka yaab AMR codec si ay u soo celiso; 192 kbps waxaas oo dhan waa mid cad oo loogu talagalay waxyaabaha badankood.

Haa - magaca, muusig, album, sanadka, lambarka raadinta, sawirka album, iyo calaamadaha faqradaha (waxay muhiim u yihiin buugaagta maqalka) waxaa laga akhrin karaa MP3 waxaana lagu qoray AMR baakadka halkaas oo AMR qaabku taageerayo astaamaha. M4B audiobook dhismaha safarka wareega M4B iyo AAX → M4B soo saarka.

Haa - ku rid faylka MP3 faylasha oo aan u dhaqaajin karno si isku mid ah. Premium waxay leedahay shaqaalaha isku midka ah oo aan lahayn xaddiga faylka, sidaa darteed 500-file batch wuxuu ku dhammaadaa daqiiqado ka badan alaabtii daqiiqadaha.

By default haa (48 kHz MP3 → 48 kHz AMR). Haddii aad u baahan tahay in ay hoos u soo bandhigaan si ay u wada shaqeeyaan (tusaale ahaan 96 kHz → 44.1 kHz si ay u CD burning) ka horumarsan tusaale-ka-raac ikhtiyaarka sameeyaan this la tayo sare ah resampling.

Haa - ikhtiyaarka loodness-normalize wuxuu ku habboon yahay ITU-R BS.1770 / EBU R128 caadiga ah ee AMR soosaarka, oo ku lug leh -14 LUFS (sharciga qulqulka), -16 LUFS (sharciga podcast), ama -23 LUFS (sharciga buugaagta maqalka).

MP3 ciyaarta adduunka oo dhan. AAC ciyaarta on Apple, Android ugu badan, Sonos. FLAC ciyaarta on Sonos iyo Android, ka yar oo wanaagsan on iPods hore. M4B audiobooks ciyaaraan la qaybta navigation on iOS Books, Audiobookshelf, iyo Smart Audiobook Player.

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. Si gaar ah muhiim marka la shaqeynayo buugaag audiobook ah.
