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. 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 pūoro katoa.

Kāore e taea te whakaora i ngā auautanga kāore i te ngaro - kāore anō kia waihangatia i te tuatahi. Ko te MP3 e whakawāteatia ana e te AAC me te Opus i ia mokatere tātai, kāore e taea te rokiroki i ngā kanikani nui ake i te rua, ā, ka tāpiri tonutia he whakamutu ā-waenga iti.

He aha te bitrate ka whakamahia e te pūkete AMR?
