OPUS Technical Specifications

File extension.opus
File categoryAudio
Stands forOgg OPUS
DeveloperXiph.Org
OverviewIt is a format for audio files which compresses the audios using lossy compression. It neglects the redundant information which can not be processed by the human ear. Internet Engineering Task Force (IETF) has standardized this format. It has superseded the Vorgis and Speex. It offers low latency i.e. there is a less delay in the signal when it enters the system and when it emerges out, this results in real-time interactive communication like video conferencing. Due to its good audio quality, it is widely used by in various listening tests.
Technical descriptionOPUS has good compatibility with low-end embedded processors as it is less complex. Ranging from 6kbps to 510kbps, it can support both variable and constant bitrate coding. Also, the frame size from 2.5ms to 60ms is supported by this codec. It works smoothly and maintains stability (by avoiding the distortion) while mixing of packets from distinct streams. Speech, Hybrid and pure-CELT are the three different methods used for encoding the audios of varied frequencies. For compressing the Speech up to 8kHz, SILk is used which is an audio compression developed by Skype Limited. The next mode, Hybrid uses CELT to compress the audio files above 8kHz frequency or for wider bandwidth and frame sizes 10ms and 20ms are supported by this mode. CELT(Constrained Energy Lapped Transform) is an open and free audio compression format which is especially used in communication that requires low latency. For general audio, the last mode pure-CELT is used. CELT is used for frame sizes which are less than 10ms.

WEBM Technical Specifications

File extension.webm
File categoryVideo
Stands forWeb Media file
DeveloperGoogle(Initially developed by On2, Xiph and Matroska)
OverviewWEBM is a multimedia container used for both audio and video formats. It is open-source and royalty-free software due to this, it can be implemented and changed for improvement by any developer. It uses different codecs to compress files. For instance, for video streams compression it uses VP8 or VP9 video codecs and for audio streams, it uses Vorbis or Opus audio codecs. It provides videos of the highest quality and that too with real-time delivery. It provides users with the playback option on any device which is due to the low computational footprint. It is licensed under BSD(A family of acceptable free software licenses). Besides this, it has another project named as Webp for images.
Technical descriptionIts structure is based on the Matroska container. That is why it can support both multiplexing and de-multiplexing. It uses core technologies like HTML, HTTP and TCP/IP which can be easily implemented and this is the main reason for its success. VP8 and VP9 are highly efficient to provide video of the highest quality. It is cost-effective due to its greater efficiency for bandwidths. It is a substitute for H.264 and MPEG4 which are patented software and have copyright. Videos of this format allow playback but it is possible only in Android version 2.3 that is Gingerbread and above. When ‘Rockchip’ came into the market in 2001 it made possible the implementation of full hardware of 1080p. Also, LiVES video editor version 1.4.9 allows coding and deflating of videos in real-time.
