WAV igcina ngokuvamile i-PCM engacindezelwanga engaqondakali — yonke isampula igcinwa ngokugcwele, noma yikuphi ububanzi be-bit nesampula yezinga elithathwe.

I-AAC izwakala ingcono kakhulu kune-MP3 ngaphansi kuka-128 kbps futhi iyi-audio track ejwayelekile ku-MP4, YouTube, Apple Music ne-broadcast.

Ingabe urekhodi olude WAV luzokhuphula ngokuphumelelayo?

Ama-akhawunti amahhala afinyelela ku-100 MB ngefayela ngalinye, futhi WAV ahamba ku-10 MB ngomzuzu ngayinye kwi-stereo ngoba akukho okucindezelwe - yonke isampula igcinwa ngokubanzi okugcwele. Amaminithi ayishumi akhona emkhawulweni. I-Premium iphakamisa umkhawulo ngokuqinile, futhi ifomu line-4 GB ye-cage yayo ngaphesheya, ngakho-ke izingqungquthela ezide zifika zihlukaniswe zibe yizingxenye ezilinganiselwe; zulazisa ndawonye futhi zithathwa njengemisebenzi eyodwa. WAV ikhulu kakhulu — cishe i-10 MB ngemingwane ye-stereo ngekhwalithi ye-CD — futhi ifomu elidala line-4 GB ye-loft futhi akukho indawo ye-tags efanele.

Ihele AAC liphele nini nge-bitrate?

Iphutha 192 kbps ku AAC olahlekelwayo; dlula-nge- AAC ongalahlekelwayo. Nciphisa ku 320 kbps uma ufuna ubukhulu obuphezulu bokungathembeki okulahlekile, 128 kbps ku-podcast yokusabalalisa obukhulu-bulinganiselwe, noma 96 kbps ku-voice-only sources lapho ifayela elincane libalulekile kunemininingwane yestudio.

Ipayipi lisebenza ngehardware esilawula ngayo kusukela ekuqaleni kuya kukuphela; akukho inkonzo yeqembu lesithathu ethola ifayela lakho.
