Format Details
MP3
MP3 (MPEG Audio Layer 3) is the world's most popular digital audio format, developed by the Moving Picture Experts Group in the early 1990s. It uses psychoacoustic lossy compression to dramatically reduce file sizes while retaining audio quality that is perceptually adequate for most listeners. MP3 transformed the music industry by making digital music portable enough to share over the internet and store on devices with limited storage.
OPUS
Opus is a totally open, royalty-free, highly versatile audio codec. Opus is unmatched for interactive speech and music transmission over the Internet, but is also intended for storage and streaming applications. It is standardized by the Internet Engineering Task Force (IETF) as RFC 6716 which incorporated technology from Skype's SILK codec and Xiph.Org's CELT codec.
