Tahuri AMR Tuhinga o mua MP3

Heoi, ā, e tika ana te whakarite i te taha. He ngaro nga āhuahira e rua, nā reira ko te MP3 encoder e mahi ana mai i te oro, kua puta kētia e tētahi whakawhitinga psychoacoustic, ā, ko ōna whakataunga anō e whakakotahi ana i te tautuhi tuatahi. I te 192 kbps, i runga ake rānei i te hua, he mārama tonu te hua mō te nuinga o te whakarongo. Mēnā kei a koe tētahi māngai kore ngaro i tētahi wāhi, ka whakakōrerotia te MP3 mai i tērā, ka kore e taea te whakawhiti i te whakawhitinga rua katoa. Ko te AMR he pūkōrero kōrero whāiti e haere ana i waenganui i te 4.75 me te 12.2 kbps, e tauira ana i te whakawhitinga reo tangata i te wā o te pūoro oro katoa. He ngaro te MP3: ko te tauira ā-hinengaro e whakakore ana i ngā auautanga kāore e taea e te oro te mōhio, i te nuinga o te wā i te 128 ki te 320 kbps.

Heoi, ā, he whiwhinga tūturu i runga i te AMR, kāore he wāhi e whakawhirinaki ana ki te rokiroki i tētahi o ia. MP3 e mau ana i te taitara, te kaitapere, te pūrākau, te tau, te tau rererangi me te toi kāwai i roto i te kāwai anō, kia tika ai te pūranga pūoro me te kore e whakawhiti i te kāwai. Kāore he mea e whakawātea ana i te MP3 mō te ōritetanga — ko ngā pūrere waka, ngā pūrere ā-rohe, ngā DAP me ngā pūrere o te rua tekau tau e whakaako ana i a ia me te kore pātai.

Nā te mea he pūkōrero kōrero tētahi taha o te pūkōrero, ehara i te pūkōrero pūoro. E tauira ana i te pūkōrero tangata, ā, ka whakakore i ngā mea katoa i waho o te awhe whatunga, he pai mō te pūrongo reo, he tūkino hoki mō ngā mea katoa me ngā pūrere i roto. Kāore e taea te whakaora i ngā auautanga kāore i te ngaro - kāore anō kia waihangatia i te tuatahi. Ka whakangaromia e AMR te pūoro: ka tangohia e tōna awhe 8 kHz ngā mea katoa i runga ake i ngā auautanga tātari, ā, kāore he nui o te whakakōrerotanga e hoki ana ki a ia.

Mēnā he ngaro te AMR ā, he kore ngaro te MP3 (hei tauira, MP3 → WAV), kāore te MP3 faila i te pai ake i te AMR — kāore e taea e koe te whakaora i ngā mōhiohio kua whakawāteatia. Mēnā he kore ngaro te AMR ā, he ngaro te MP3, e tūmanako ana te MP3 codec ki te whakawhāiti anō; i te 192 kbps he mārama tēnei mō te nuinga o ngā ihirangi.

Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.

Mā te pūmau, ā, (48 kHz AMR → 48 kHz MP3). Mēnā e hiahiatia ana e koe te whakaiti i te tauira mō te ōritetanga (hei tauira, 96 kHz → 44.1 kHz mō te pūngao CD) ka mahi tēnei te kōwhiringa tauira ā-whakapaina ki te whakawātea ā-whakapaina.

Not in this step. The converter has no loudness setting and leaves the level as it is. To even out the volume, run the finished MP3 through a Normalize tool on this site.

MP3 plays almost everywhere. AAC plays on Apple devices, most Android phones and Sonos. FLAC plays on Sonos and Android but not on older iPods, and WAV plays on nearly everything but makes large files. There are no device presets on this page, so choose the target format your player supports.

Yes. Nobody listens to or shares the audio, which matters for personal audiobook libraries, and uploaded AMR files and their converted copies are deleted automatically about 24 hours after conversion.
