MP3 visit WAV file format

The digitization of speech and music has been around for a long time, Remember tape decks, reel to reel and 8 Tracks? The problem with these types of devices is that it is based on a magnetic tape that loses its quality over a period of time. Then came along compact disk CD for short and revolutionized the music industry with promises of high quality sound and scratch resistance, yea right!, compared to the old vinyl disk. Ho! How I miss the vinyl disk. The sound richness of vinyl just made my listening more enjoyable and closer to listening to real musical instruments. Now remember that digitizing real analogue instruments like a guitar or piano involves sampling or taking a sample at a very high frequency and saving the result via an analogue to digital converter to a hard disk or compact disk CD. Then the reverse is also true in that a digital to analogue converter is used so you can hear the sounds back in an analogue way.
Now note that a typical CD hold about 20 songs and that they are saved in a WAV format with a quality that is pretty good. Then came along the MP3 format, a format in my view is acceptable for speech but not for music listening, now I say this for those of us who appreciate all the nuances of what analogue instruments provide. Lets take a guitar for example. If you ever listen or played one you will know that the sound quality is at the maximum level because they has been no transformation or manipulation of the wave form.
At the medium level you have CD quality format that is very close to the original sound waves and at the lowest level, due to further digital compression, in order to minimize disk space you have the MP3 format. So it is a question of less quality over quantity.
Now for some consumers the MP3 format is quite acceptable for music listening but let’s not forget how music is first created and the processes involved.
MP3, WAV
