Information about AAC and FLAC file formats
|🔸 File format
|🔸 Full name
|AAC - Advanced Audio Coding
|FLAC - Free Lossless Audio Codec
|🔸 File extension
|🔸 MIME type
|🔸 Developed by
|Bell Labs, Fraunhofer Institute etc.
|🔸 Type of format
|Audio compression format
|Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates. ISO and IEC have standardized AAC as part of the MPEG-2 and MPEG-4 specifications.
|FLAC (Free Lossless Audio Codec) is an audio coding format for lossless compression of digital audio and is also the name of the reference codec implementation. Digital audio compressed by FLAC's algorithm can typically be reduced to 50-60% of its original size and decompress to an identical copy of the original audio data.
|🔸 Technical details
|AAC supports the inclusion of 48 full-bandwidth audio channels in one stream plus 16 low-frequency effects channels, up to 16 "coupling" or dialog channels, and up to 16 data streams. The quality for stereo is satisfactory to modest requirements at 96 kbit/s in joint stereo mode; however, hi-fi transparency demands data rates of at least 128 kbit/s.
|The technical strengths of FLAC compared to other lossless formats lie in its ability to be streamed and decoded quickly, independent of compression level. Compared to compressed audio formats, FFmpeg's FLAC implementation was noted to have the fastest and most efficient embedded decoder of any modern lossless audio format.
