What is a OPUS file?
OPUS is a modern, highly flexible audio codec developed by the IETF and Xiph.Org Foundation. It combines the best aspects of Skype’s SILK and Xiph’s CELT codecs to deliver excellent audio quality across a wide range of bitrates and applications — from voice calls to streaming music.
OPUS is especially useful in real-time communication tools like Zoom, Discord, and WebRTC-based browsers. It adjusts dynamically to network conditions, providing smooth and clear sound even with bandwidth fluctuations.
How to open OPUS files
OPUS files are supported by VLC, Foobar2000, Audacity (with plugin), and mobile apps like Opus Player. WebRTC-compatible browsers also support this format.
To convert OPUS to more widely used formats like MP3 or AAC, use AnyConv online for a fast result.

What is a M4A file?
M4A stands for MPEG-4 Audio and is a popular audio format used for storing compressed audio files. Unlike MP3, M4A files often use AAC encoding, which provides better sound quality at similar file sizes. It was developed by Apple and is widely used in iTunes and iOS devices.
M4A files are typically used for music and podcasts, offering high efficiency and compatibility with modern players. Since they don't support digital rights management (DRM), they are preferred for unrestricted distribution of audio content.
How to open M4A files
M4A files can be opened with iTunes, QuickTime, VLC Media Player, and most smartphone music apps. They’re fully supported on macOS, iOS, and many Windows players.
To convert M4A to MP3 or WAV, use AnyConv for a fast and simple online conversion.
