Opus is a free, open-source audio codec developed by Xiph.Org and the IETF, standardized in 2012 (RFC 6716). It supports bitrates from 6 kbps to 510 kbps, covering both low-bitrate voice calls and high-quality music streaming with a single codec. Opus consistently outperforms MP3, AAC, and Vorbis at equivalent bitrates in independent listening tests. It is used by YouTube, Spotify, Discord, WhatsApp, Zoom, and WebRTC applications. Opus is natively supported in Firefox, Chrome, Edge, and most modern media players including VLC, MPV, and foobar2000, across Windows, macOS, Linux, Android, and iOS.

FLV file is a bitstream created for video transmission over the Internet. Audio information in flv files is usually encoded in mp3, but other formats are also possible. Being one of the oldest flash-formats, FLV is very popular because of its simplicity, although it is inferior to more modern formats in quality, especially when using a low bit rate. Although the format is primarily intended for streaming video, it can also be used to store information locally.
