I M4A kusvika ku AAC kushandurwa kuri kudzokera?

Iwe unogona kushandura AAC kuma M4A pane iyi saiti. Kana imwe yemhando dziri kutaurwa iri nematambudziko, iyo round-trip haisi bit-perfect kunyangwe ichionekwa kana kutaurwa.

Ndeipi mhando yemufananidzo ndinofanira kutarisira kubva kuM4A kusvika kuAAC?

Default settings target broadcast / web quality — visually identical to the source for most viewers. For archive use, pick the highest quality option in the converter settings.

Kushandura M4A kuenda ku AAC kunodzokorora sei audio?

Hapana chikonzero. M4A uye AAC vanotakura mavhidhiyo kubva kune imwe encoder - izvo zvinosiyana ndezvekuzvitakura - saka mavhidhiyo akavharwa akavharwa akakopwa pasi pekusingaperi uye chete header uye tag block inonyorwazve. Hapana chinhu chinodecoding, hapana chinhu chinodzokororwa, uye izvo zvinobuda zvinove zvebit-identical audio munguva pfupi kupfuura muminetsi. Izvi zvinokosha kupfuura zvazvinonzwa: chero chaiyo re-encoding yeazvino-lossy audio inodhura mhando iyo hapana nhanho yapfuura inodzokorora, saka kushandurwa kwauri kunogona kuderedza munhu wese anofanira. AAC inonzi Advanced Audio Coding, yakanyorwa muna 1997 se MPEG-2 Part 7 uye yakagadzirwa kuti igadzirise MP3.

Kushandura M4A kuenda ku AAC ndeimwe yekupedzisira yekuvhara kunonoka?

Yeah, uye zvinokosha kutarisira. Both formats are lossy, so the AAC 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 AAC from that instead avoids the double pass entirely. An M4A iine AAC mumamiriro ezvinhu akawanda, kana Apple Lossless (ALAC) apo yakaita kubva ku lossless kurova. AAC ine kushaya simba asi iri nyore kushandisa kupfuura MP3, uye inochengeta kusvika pa48 machannels zvakananga sezviri, kwete sezvaiita stereo.

Chii chakakodzera kuti chiite AAC faira?

A bare run of encoded audio frames with no container wrapped around them. That's why two AAC files can usually be joined by simply putting one after the other, and equally why everything beyond the audio itself — a length, a seek index, cover art — has to be bolted on as a convention rather than being part of the format, so a player often has to read the entire file to work out how long it is. 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.

Nei foni yangu kana tafura yainge yarekodha mu M4A?

Nekuti ndezvekuti iyo hardware encoder pachigadzirwa chinogadzira. Mifananidzo yezwi, kurodha skrini uye vhidhiyo yezwi yezvose zvakagadzirwa nefoni zvinobuda se M4A pasina munhu achizvisarudza, izvo zvinoita kuti zvinyorwa zvakawanda zviende mukati mechirongwa ichi uye kuti sei mhando inowanzova yakanaka kupfuura saizi yechirongwa ichi. Hapana chinhu chinoita kuti chigadziriso chirege kuchinja; zvinoreva chete kuti chigadzirwa chakanyorwa kamwe chete, nechip yakagadzirirwa kurarama kwebhatiri kupfuura kuvimbika.
