FLAC is a codec that compresses a lossless audio file. These files are often used in professional recording studios. However, this format implies some compression of information, so the same song in FLAC format can take up to half less memory than the original CD. And if, for example, you copy music from a CD into this format, it will not differ in any way from the original, regardless of its bit rate or frequency range. The compression ratio and bit rate vary depending on the complexity of the material to be compressed - for example, singing with a guitar lends itself to compression better than recording a symphony orchestra. FLAC is often used to create audio collections and are used for listening on premium equipment.
OPUS file is an audio file created in the Opus format, a lossy audio format designed for streaming on the Internet. It uses both SILK (used by Skype) and CELT (from Xiph.Org) codecs and supports variable bit rates from 6 kbps to 510 kbps. Opus is a completely open source, royalty-free, highly versatile audio codec. Opus is good for streaming both speech and music over the Internet. The Opus codec is used for Voice over IP (VoIP), video conferencing, in-game chat. The Opus format is supported by various software, including the TeamSpeak VoIP application, the Mozilla Firefox browser, the GStreamer framework, and the VLC media player. The main advantages of OPUS are the high audio quality and good compression achieved through dynamic adaptive streaming.
