Overview

It 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 It has superseded the Vorgis and Speex.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 description

OPUS 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.

Overview

It is an audio file format which is proprietary or closed source software. It is available in four different versions. First one is the original WMA codec. This gives competition to the MP3 and it came into existence in 1999. Next is WMA Pro which is an advanced and new codec. It uses lossy compression but provides audios of high resolution. The third is WMA lossless codec and it encodes audio without losing any information. Lastly, there is WMA Voice which is again a lossy compression and it was developed for audios with low bandwidth or low bit rates. Microsoft has developed an advanced systems format which is used by ‘Windows Media Audio' to store encoded audios. Metadata objects like the album, the genre of track and title; etc. can also be added in this codec. The prime use of this extension by users is streaming on the internet.

Technical description

Microsoft has various claims about this codec. Firstly, it was alleged that at 64kbps this format will deliver the same quality of audio as of CD. This was rejected at the end. The second claim is that it gives better sound quality than MP3 at the same bit rate. Thirdly, it was professed that this extension provides a similar quality of audio at a lower bit rate than MP3 at a higher bit rate. Apart from this, there is an option available for this container i.e. DRM(Digital rights management) and this option is completely elective. One may or may not choose this choice. A number of software support this format like Windows media player, Microsoft expression encoder; etc.
