About the formats

Extension flac
Category Audio/Music file formats
Developed by Xiph.Org Foundation
Mime type audio/flac

Description

FLAC, or Free Lossless Audio Codec, files contain digital audio. FLAC files utilize lossless quality, meaning that there is no loss of any original sound data. When compared to MP3 (lossy audio format), FLAC files are generally larger. Nonetheless, FLAC’s lossless compression algorithm can reduce audio by up to 70%, and still be able to reproduce the original audio afterwards. The format is royalty-free.
Extension aac
Category Audio/Music file formats
Developed by Fraunhofer Institute, Nokia, Dolby, AT&T, Sony and others
Mime type audio/aac

Description

AAC files are audio files using Advanced Audio Coding compression. AAC is a lossy format, meaning the audio quality remains almost the same as the original source. The slight loss leads to the audio files taking up less space, which makes them ideal for music streaming or when bandwidth is limited. AAC is superior to MP3 for handling frequencies above 16 kHz. The encoding efficiency for transient and stationary signals is also better when compared to MP3.
