Opus to WMA: How to Convert Opus Files Easily

by Christine Smith • 2023-06-01 14:11:16 • Proven solutions

The OPUS format was specifically designed to be used on the web. As such, it is widely used in applications related to real-time audio-specific web streaming services. It offers low compression in contrast with other audio formats, thus maintaining better quality and minimal degradation upon transfer across the web. Despite having the same bitrate as MP3, an OPUS track has a noticeably better quality to it.

That said, OPUS is a very uncommon audio file format that is sidelined by other, more mainstream formats. In this tutorial, you'll learn how to convert an OPUS to WMA format to be used on a Windows computer.

Part 1. What is an Opus File

OPUS, or OGG Opus, is a lossy audio file format that was originally devised by IETF to support internet streaming. For this purpose, it makes the use of the SILK codec, perhaps most known for its use in skype as well as the CELT codec. As of now, it is being maintained and updated by Xiph.Org.

Files with OPUS extensions are some of the most accessible audio file formats, with popular media players such as VLC and AIMP are able to load an OPUS file without any impediments. The bit rates supported by Opus are in a range between 6kb/seconds to 510 kb/seconds. Its codec sees frequent use in different venues such as Voice over IP, video streaming and sessions, etc. Despite this, OPUS is still an obscure audio codec because internet streaming is a very specific use.

For a file format designed to work on the internet, it works surprisingly well on local storage. For this reason, you might want to consider converting your OPUS files to WMA format.
