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 It has superseded the Vorgis and Speex.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.

3GP Technical Specifications

File extension.3gp
File categoryVideo
Stands forAlso termed as 3GPP file format
Developer3rd Generation Partnership Project(3GPP)
Overview3GP file format is compatible with all the 3G cell phones but it can also be used in some 2G and 4G phones with certain limitations. It is a multimedia container which enables various multiple streams to be embedded into a solo file. It is used both for video and audio files. This format gives an opportunity to the user to edit, modify and transfer files on mobile devices. This aforesaid facility is available online as well. Multimedia messaging service(MMS) and Multimedia Broadcast Multicast Services(MBMS) use this extension for all media files that needed to be sent using cellular or wireless connection. Furthermore, it takes less storage space thus prevents files to consume more disk capacity.
Technical descriptionThis extension is based on ISO Base Media file format, MPEG-4 Part 12. It is specially designed for GSM(Global System for Mobile Communications) based phones and tablets. It should be noted that there are few cellular phones that use .mp4 extension to store 3GP video files. Besides this, the smaller bandwidth requirements lead to an easy transmission of files over the Internet. In this type, video streams are stored as MPEG-4 Part-2, H.263 or MPEG-4 Part-10 (AVC/H.263). And AMR-NB, AMR-WB, AMR-WB+, AAC-LC, HE-AAC V1 or HE-AAC V2(This is enhanced AAC PLUS) are used for audio streams. There are various programs linked to this format like QuickTime player, VLC Media Player and Windows Media Player; etc. Apart from this, the Nintendo 3DS also use its technology to play YouTube videos. These files can also be coded and deflated with open-source software.
