About Opus Format
Opus is a modern audio codec developed by the Xiph.Org Foundation and standardized by the IETF. It was designed to be a versatile, low-latency audio codec suitable for both speech and music. Opus provides excellent compression efficiency and is widely used in streaming, web applications, and voice communication.
History and Development
Opus was developed by the Xiph.Org Foundation and standardized by the IETF in 2012. It was designed to replace older codecs like MP3 and AAC with a more efficient, open-source alternative. Opus combines technologies from Skype's SILK codec and Xiph.Org's CELT codec to provide excellent quality at low bitrates. The format quickly gained adoption in web browsers, streaming platforms, and voice communication applications.
Technical Specifications
Opus is a lossy audio codec that supports variable bitrates from 6kbps to 510kbps. It can handle both speech and music content, automatically adapting its encoding techniques. Opus supports sample rates from 8kHz to 48kHz and can encode mono or stereo audio. The codec is designed for low latency, making it suitable for real-time applications like voice chat and streaming. Opus is completely free and open-source with no licensing restrictions.

MP4 to Opus Conversion
MP4 videos contain both video and audio tracks. When converting to Opus, the video track is removed and only the audio track is extracted. The audio is then encoded in Opus format using Opus compression. The conversion process preserves the audio quality while removing the video data, resulting in much smaller file sizes.
Format Limitations
Opus has some limitations compared to MP4: it only contains audio, so video information is lost. The format may not work on all devices, especially iOS devices without third-party apps. Some older players may require conversion to other formats. However, Opus provides better quality than MP3 at the same file size and is completely free and open-source.
