Information about MP3

File extension
mp3
File category
Audio
Stands for
MPEG Audio Layer-3
Developer
Fraunhofer- Gesellschaft (A German research institute)
Overview
It is a digital Audio which compresses the tracks using the lossy format. Although, it follows the lossy format, yet, there will be no noticeable change in the quality of audio. It only discards the superfluous information that a human ear is inefficient to process or hear. With the help of the this extension, one can upload and download audio files with ease, irrespective of the internet connection speed even a dial-up connection users can access these files. There are a number of MP3 Blogs(music blogs) available on the internet where maker uploads music files and a user can download the same without any trouble. These blogs help people to get an insight into the music world. Hype Machine is an example of an audio blog.
Technical description
MP3 uses lossy data compression, which means when data is encoded it is not the full original version, it’s a substitute to original copy but in a smaller size. This compression can lead to a decrease in file size, ranging from 75% to 95%. This format is based on perceptual coding due to which this extension screens out the noise, and results in an audio file that uses a low bit rate(lowest bit rate in it is 128kbps). It provides audio of fair sound quality. As it is only an audio file, thereby, if there are any images linked to it then they need to be stored in a separate file.

Information about OPUS

File extension
opus
File category
Audio
Stands for
Ogg OPUS
Developer
Xiph.Org
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 It has superseded the Vorgis and Speex.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.
