OverviewIt 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 descriptionMP3 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.

Stands forWaveform Audio File Format
DeveloperMicrosoft and IBM
OverviewWAV or WAVE is an audio format which was developed to store audio files on personal computers. These files include music, spoken or speech audios and sound effects. The size of the files in this codec is very large as it does not use a lossy format like MP3. This is the main reason why this format has lost its popularity. Due to its size, it is hard to transfer files over the internet which had resulted in less acceptance. This format is supported by many programs like a window Media player. Therefore, these audio files can be played using aforesaid software. One can not completely ignore this format as it provides high quality of audios. Due to this, it is used for radio broadcasting.
Technical descriptionThis format supports metadata that is why we can add details using information chunk. Data in this codec is stored in chunks as it is an application of RIFF(Resource interchange file format). Furthermore, LPCM(Linear pulse code modulation) is the most common, uncompressed audio format in this, but it can also store compressed audio like MP3. Also, it is especially used by professionals as LPCM audio format offers a maximum quality. Only files up to 4 GB are supported by this format which is one of the limitations in this format. This is because of 32-bit unsigned integer which carries the file size header. To overcome this, W64 format came into existence which can record long audios as it enables 64-bit header.
