О конвертации AAC в FLAC
AAC delivers perceptually transparent audio through lossy compression, typically at 128-256 kbps. FLAC (Free Lossless Audio Codec) stores audio with perfect bit-for-bit accuracy while achieving 50-70% compression versus raw PCM. Converting AAC to FLAC decodes the lossy AAC data and re-encodes it losslessly, producing a file that preserves every sample the AAC decoder outputs. This is commonly done for archival purposes or to prepare files for workflows that require lossless input.
Зачем конвертировать AAC в FLAC?
Lossless audio editors and mastering chains expect FLAC or WAV input. If you apply effects to an AAC file and re-export as AAC, you compound lossy artifacts with each generation. Converting to FLAC first gives you a lossless working copy that survives unlimited editing cycles without further degradation. FLAC is also the standard archival format on Linux and Android, supported natively without extra software.
