Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une-lossless master nganoma yikuphi, ukukopisha i-MP3 kusuka kulo kunciphisa ukudluliswa okuphindiwe ngokuphelele. MP2 ilahlekelwa yinto kodwa isebenzisa isihlungi esilula kunaso iMP3, isebenza nge 192 kuya ku 384 kbps.

Noma yini esekelwe ku-channel ehlukile ihamba lapho lokhu kwenziwa. I-MP3 ihlukaniswe ngokukhethekile yi-AAC ne-Opus nganoma yisiphi isivinini se-bit, ingagcina ngaphezulu kwama-channels amabili ngokunembile, futhi ihlala ifaka ukulibazisa okuncane kwe-encoder.

Ihele MP3 lisebenzisa i-bitrate enjani?

Iphutha ngu-192 kbps ku MP3 olahlekelwayo; udlulisa-nge- MP3 ongenalutho. Nciphisa ku-320 kbps ku-audiophile noma ku-64-96 kbps ku-audiobooks ekhuluma-magama (icacile ku-voice, ihlukanise ubukhulu befayela ngamaphesenti).

Ingabe ngingenza i-batch yokuguqula amahele angama-MP2 abe MP3?

Yebo — susa isibaya se MP2 amafayela ngaphakathi futhi sizoziphatha ngokufanayo. I-Premium inemisebenzi eminingi efana ne-parallel futhi akukho lutho oluphezulu lwesayizi yefayela ngalinye, ngakho-ke i-500-file batch iphele ngemizuzu endaweni yamahora angama-10.

Ingabe i-MP3 izogcina isilinganiso esifanayo sesampula njenge-MP2?
