Format Details
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.
FLAC
FLAC (Free Lossless Audio Codec) is an open-source audio format that compresses audio without any loss of quality, allowing perfect bit-for-bit reconstruction of the original recording. It typically reduces file sizes by 40-60% compared to uncompressed WAV while remaining completely lossless. FLAC is the format of choice for audiophiles, music archivists, and mastering engineers who require studio-quality audio fidelity in a manageable file size.
