Kushandura M4A kuenda ku AC3 ndeimwe yekupedzisira yekuvhara kunonoka?

Yeah, uye zvinokosha kutarisira. Both formats are lossy, so the AC3 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 AC3 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. AC-3 imhando yemultichannel audio, iyo inowanzo shandiswa pa5.1 at 384 or 448 kbps, ine metadata yekuti mashoko aite sezvinoita.

Chii chakakodzera kuti chiite AC3 faira?

A bare run of encoded audio frames with no container wrapped around them. That's why two AC3 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?
