Kodi ndi chiyani chomwe MP3 mpaka MP2 audio converter imapangitsa?

It re-encodes a MP3 audio file as MP2. Sample rate and channel count are preserved; the difference is the codec and container.

Kodi kuchuluka kwa sampling ndi ma channel adzakhala otetezeka?

Mwa default yes — stereo imakhala stereo, kuchuluka kwa sampling (44.1 kHz, 48 kHz, etc.) kumapita ku MP2 output.

Kodi kusinthidwa kwa MP3 kupita ku MP2 kumatha kusinthidwa?

Mukhoza kusintha MP2 kumbuyo ku MP3 patsamba lino. Ngati mtundu uliwonse womwe uli ndi vuto, ulendo wopita kumalo osiyanasiyana si bit-perfect ngakhale kuti ndi wowoneka bwino kapena wowoneka bwino.

Kodi kusinthidwa kwa MP3 ku MP2 ndi gawo lachiwiri la kutsitsa kwa lossy?

Yes, and it's worth planning around. Both formats are lossy, so the MP2 encoder is working from audio that has already been through one psychoacoustic pass, and its own decisions compound the first set. At 192 kbps or above the result is still transparent for most listening. If you have a lossless master anywhere, encoding the MP2 from that instead avoids the double pass entirely. MP3 ndi lossy: psychoacoustic model amachotsa ma frequencies kuti nkhope sizingayembekezere kuti adziwe, makamaka pa 128 mpaka 320 kbps. MP2 ndi lossy koma amagwiritsa ntchito zosatheka filterbank kuposa MP3, nthawi zambiri ntchito pa 192 mpaka 384 kbps.

A bare kuyendetsa encoded audio ma frame ndi palibe bokosi wozungulira iwo. Thats chifukwa chake awiri MP2 owona akhoza nthawi zambiri kugwirizana ndi kungoika mmodzi pambuyo pa wina, ndi mofanana chifukwa chake chilichonse m'mbali mwa audio yekha - m'lifupi, a kuyang'ana index, cover art - ayenera kukhala bolted pa monga chisankho kuposa kukhala gawo la mtundu, kotero wosewera mpira nthawi zambiri ayenera kuwerenga zonse owona kuti ntchito kunja mmene m'lifupi ndi. It's about the simplest thing that can be called an audio file, which is exactly why it turns up inside other containers more often than on its own.

Ngati ma diski alibe pa shelf, kubwezeretsa ku mtundu wopanda kusowa ndi kulemba kuchokera komwe kumapatsa zotsatira zabwino kwambiri kuposa kusintha kwa mafayilo omwe alipo. MP3 ndi MPEG-1 Audio Layer III, anamaliza mu 1993, ndibe kwambiri universally decodable audio mtundu kuti ali.

Kodi MP3 ndi youlere kugwiritsa ntchito ndi kugawa?

Yes, popanda zofunikira zofunika kuganizira. Specification ndi anthu, aliyense angagwiritse ntchito encoder kapena decoder popanda kufunsa kapena kulipira, ndipo palibe amene angasinthidwe ndi mawu amenewa pambuyo pake - chifukwa chake amawonekera m'mapulogalamu otsegulira, m'ma injini a masewera ndi kulikonse komwe kuvomerezedwa kwa lisensi kungakhale kuwononga ntchito. Kusintha kuchokera kwa izo sikunachitike; mafayilo omwe mwakhala muli nawo amakhalabe oyenera kugwiritsa ntchito monga momwe anali.

N'chifukwa chiyani wina angakonzekere ku MP2?

Kwa m'modzi mwa mapulogalamu kapena zida zosiyanasiyana zomwe sizilandira chilichonse — zomwe ndi nkhani yoyenera komanso chifukwa chokhacho choyenera. MP2 ili ndi zaka za m'mbuyo: codecs zatsopano zimachita ntchito yomweyo ndi kukula kocheperako, osewera amtundu uliwonse amachotsa thandizo kwa izo kuposa kuwonjezera, ndipo palibe china chatsopano chomwe chimapangidwa m'madera ake. Ngati pali chinachake m'mzerecho chomwe chikufunikira, sinthani ndi kusunga choyambirira ngati mtsogoleri. Ngati palibe, sinthani kuchokera kwacho.
