WMA (Windows Media Audio) is a proprietary audio codec family developed by Microsoft, first released in 1999 as a competitor to MP3. The WMA format comprises four variants: Standard (lossy, general purpose), Lossless (WMA Lossless, for archiving), Pro (high-resolution multichannel audio), and Voice (optimized for low-bitrate speech). At equivalent bitrates, WMA Standard offers quality comparable to MP3. WMA is natively supported by Windows Media Player and Xbox consoles, and plays on most modern media players including VLC and foobar2000. While its popularity has declined with the rise of AAC and streaming services, WMA files remain common in legacy Windows environments.

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.
