Default 192 kbps for lossy AC3; pass-through for lossless AC3. Override to 320 kbps if you want maximum lossy fidelity, 128 kbps for size-restricted podcast distribution, or 96 kbps for voice-only sources where the smaller file matters more than studio detail.
Kodi kuchoka ku FLAC kupita ku AC3 kumachepetsa kwambiri mtundu wanga wa audio?

Ngati FLAC ndi yopanda kusowa ndi AC3 ndi yopanda kusowa, yembekezerani kuti AC3 encoder ibwezeretse; pa 192 kbps kuwonongeka kumakhala kosadziwika kwa nkhope zambiri.
Ndikoyenera - dzina, woimba, album, chaka, mndandanda wa nyimbo, album art, BPM, kusewera-kupeza kumawerengedwa kuchokera ku FLAC chomera ndi kulemba m'madera ofanana pa AC3 chomera. ID3v2 (MP3), Vorbis maganizo (OGG, FLAC), MP4 atoms (AAC, M4A), RIFF INFO (WAV), iXML chidutswa zonse map cleanly.

Mwa default ndi yemweyo (48 kHz FLAC imatulutsa 48 kHz AC3, 44.1 kHz FLAC imatulutsa 44.1 kHz AC3). Kuti mukwaniritse zofunikira — monga kuchepetsa 96 kHz studio masters mpaka 44.1 kHz AC3 polemba CD, kapena kuwonjezera 22 kHz voicemail mpaka 44.1 kHz AC3 — mndandanda wolowetsa wa sampling-rate umagwiritsa ntchito kuwonjezera kwa SOX-style.
Kodi ndingasinthire kuwala kwa mawu m'mawindo a FLAC mpaka AC3?
+
Ndiyo — kusankha kwa loudness-normalize kumagwiritsa ntchito ITU-R BS.1770 / EBU R128 ku AC3 output, kulenga -14 LUFS (streaming standard) kapena -16 LUFS (podcast standard) kapena malire apadera.
