- An OPUS file is an audio file created in the Opus format (also called "Ogg Opus"), a lossy audio format developed for Internet streaming. It uses both SILK (used by Skype) and CELT (from Xiph.Org) codecs and supports variable bit rates from 6 kb/s to 510 kb/s.

Opus Audio File(OPUS) is an audio coding format developed by Xiph.Org Foundation. It is efficient in speech coding, thanks to its low Latency. Its small – complexity suits its low embedded processors. It has taken the place of Vorbis and Speex in most new applications. It has also been ranked among the best audio formats.
It is a lossy audio format that is meant for internet streaming and uses the .opus extension. The file format supports bit rates ranging between 6kb/s to 510 kb/s.
OPUS uses the SILK algorithm and MDCT that is based on CELT algorithms to achieve its efficiency. The use of SILK for speech audio compression makes it the best option for use when it comes to short clips and audio. No matter the source of the audio file, the quality remains the same when compressed. The quality value of the audio can be as low as one, but the compression rate remains high.
Its the best option when it comes to Real-time applications: such as video conferencing, telephony, and Voice over IP, among others. The use of CELT codecs by Xiph based applications ensures high quality is achieved and minimal rates of delay experienced.
VLC media player, Aimp2, and foobar2000 are some of the windows programs that can open OPUS files.
