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 It has superseded the Vorgis and Speex.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.

3G2 Technical Specifications

File extension.3g2
File categoryVideo
Stands for3GPP2 (An extended form of MPEG-4 Part 12)
Developer3rd Generation Partnership Project 2
OverviewThe 3G2 format is an upgraded version of .3GP file and it functions to save both audio and video files in 3G phones which are based on CDMA (Code Division multiple access). By using this format, we can transfer files over the internet and can store videos on mobile phones. It consumes less storage space when compared to the 3GP file. Therefore, it helps to save the disk space. Also, this format is very good for mobile streaming and downloading as it supports bandwidth, which is easily compatible with 3G cell phones. Moreover, this is both ISO Base media file format MPEG-4 Part 12 and MP4 file format MPEG-4 Part 14. We can use various software to open these files. For example, Apple’s free QuickTime, VLC Media player; etc.
Technical descriptionIt is a parallel format of MPEG-4 Part 14 or MP4 but a simplified version, not the complex one. This is the perfect format for 3G cell phones to store videos as low bandwidth is required and besides this, it takes less space to store videos. 3GPP2 can store similar video and audio streams as of 3GP and some additional streams as well. For instance- AMR-NB, AMR-WB, AMR-WB+, AAC-LC, HE-AAC v1, and HE-AAC v2. In addition to these aforesaid streams, EVR-C, EVRC-B, EVRC-WB, VMR-WB are other extra streams used in this format. MPEG-4 media is stored in 3G2 format using MP4 and AVC file format specifications.
