OPUS Audio Format

OPUS Converter

OPUS, or OGG OPUS, is a free and open source audio file format. Developed by Xiph.org foundation and later standardised by the IETF (Internet Engineering Task Force), it uses lossy compression to shrink files, while maintaining a high quality sound with minimal degradation. OPUS files are encoded with SILK or CELT codecs and use the OGG container format. Originally built for online media streaming, this file format is very practical for real-time interactive and audio-specific web streaming services with low delay (latency).

It is a very versatile file format, accommodating both high and low bitrates. That said, OPUS isn’t as widely used compared to more well-known audio file formats, being sidelined by other formats such as MP3 and WMA. Typical uses for OPUS files include web-based audio and video streaming, video conferencing, gaming, and radio broadcasting. OPUS files can be opened using compatible browsers such as Chrome, Firefox and Opera, but can’t be played by typical Mac media players or by Windows Media Players prior to the 2022 version. Alternative multimedia players such as VLC, FFmpeg or AIMP, however, do support the OPUS format.

VTT Document Format

VTT files are text files which contain extra information about web videos, such as subtitles, captions, descriptions, chapters, and metadata. The standard for Web VTT was developed by the World Wide Web Consortium (W3C) in 2010 in response to a perceived need for greater flexibility when displaying video online. Each VTT file contains timed text tracks on single line or multiple lines, with data about subtitles to display. Files are similar to another popular subtitle format, the SRT file, but VTT is more extensible - it allows for customisation of font-sizes and colours and the ability to store metadata about the video, such as the title and the author. Popular video sharing sites such as Youtube and Vimeo support VTT files, and they can also be used on social media platforms such as Facebook, Twitter and LinkedIn.
