Tips
What is FLAC?
FLAC, the abbreviation for Free Lossless Audio Codec, accomplishes data compression without sacrificing the integrity of the audio source. FLAC's free and open source royalty-free nature makes it well-supported by many software applications. Audio sources encoded to FLAC are typically reduced to 50-60% of their original size. Compared to lossy formats like MP3, FLAC playback support in portable audio devices and dedicated audio systems is limited at this time.
What is MP3?
MP3, standing for MPEG-1 Audio Layer 3, is a patented digital audio encoding format using a form of lossy data compression. It is a compressed audio format that allows for smaller file sizes with similar sound quality. Audio sources encoded to MP3 are typically 10 to 12 times smaller than their original size. It is a common audio format for consumer audio storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on digital audio players.
