About FLAC
FLAC (Free Lossless Audio Codec) is an audio file format that uses lossless compression. It was jointly developed by Xiph.Org, Josh Coalson and Erik de Castro Lopo in mid 2001. Due to its lossless compression, it maintains the sound at its best, making it high quality, versatile and efficient. It’s among the formats that are open-source.
About AAC
AAC (Advanced Audio Coding) is an audio format primarily used to maintain compressed version of digital audios. It’s considered to be more efficient than MP3 and WAV due to various factors. It was released by MPEG organisation in late 1997. The key features of AAC include larger channels, better frequency resolution and small size.
