Explanation: 

Detailed explanation-1: -MP3 (MPEG-1 Audio Layer III) is the most popular of the lossy formats. MP3 files work on most devices and the files can be as small as one-tenth the size of lossless files. MP3 is fine for the consumer, since most of the sound it drops is inaudible, but that’s not the case when it comes to bit depth.

Detailed explanation-2: -In practice, MP3 offers advantages because the files can be streamed easily and usually without disruptions over the Internet as a result of their small size. This allows you to easily distribute your music without technical difficulties.

Detailed explanation-3: -Firstly, the MPEG Layer 3 format (MP3 for short) supports different levels of data compression. Perhaps the most common is 128kbps (kilobits per second), but 48, 56, 64, 96, 192 and more are all in use. The lower the bit-rate, the more extreme the compression, and the more obvious its audible consequences.

Detailed explanation-4: -In general, WAV files are better quality than MP3 files, but this isn’t always the case if the WAV file has been compressed. A lossless WAV file is always best for recording and for carrying high-quality audio files. MP3 files are not bad quality but WAV is more elite.
