4.33 from 6 Reviews

The Opus Audio Codec is the industry-standard audio compression solution for crystal-clear voice calls, gaming audio, and music streaming.

This download includes the complete encoder, decoder, and essential DLL files.

What You Get in This Download

This package provides everything needed to encode and decode Opus audio files on Windows:

Opus encoder (opusenc.exe) - convert audio files to .opus format.
Opus decoder (opusdec.exe) - convert .opus back to WAV.
Essential libraries (libogg.dll and libopus.dll).
Automatic foobar2000 integration for .opus playback.

Why Choose Opus Over Other Audio Codecs?

Opus delivers superior audio quality while using minimal bandwidth and storage space.

Unlike MP3 or AAC, Opus automatically adapts bitrate based on content type - switching seamlessly between speech optimization and full-bandwidth music encoding.

The codec excels in real-time communication applications including Discord, Microsoft Teams, Zoom, and WebRTC-based services.

Online gaming platforms rely on Opus for low-latency voice chat that remains clear even on unstable connections.

Media Player Support

Major media players handle Opus files natively. VLC Media Player plays .opus files without additional configuration. MPC-BE and MPC-HC support Opus through their integrated LAV Filters.

For Windows Media Player and other DirectShow-based players, install DC-Bass Source Mod or add LAV Filters to enable Opus decoding.

The K-Lite Codec Pack includes Opus support through its bundled LAV Filters component.

Several free converters handle Opus audio conversion alongside FLAC, MP3, and Ogg Vorbis formats:

LameXP - batch converter with advanced encoding options.
TAudioConverter - straightforward interface for quick conversions.
Opus GUI - dedicated Opus encoding with full parameter control.
winLAME - wizard-style converter supporting Opus output.
fre:ac - open-source encoder with CD ripping capabilities.
