How To Solve Windows 7 MP3 Problem

How to solve Windows 7 MP3 problem

Sometimes the MP3 files can’t be played

MP3 is not illegal. It is simply a file format.

There’s no denying that MP3 files can be used illegally, but so can your cassette deck. The publicity about law-breaking MP3 pirates shouldn’t dissuade you from taking an interest in this revolutionary way of delivering music.

Size Matters

if it’s just a file format, then what’s so special about it? Let’s start with what we had before the arrival of MP3. The most common audio file format used in computing was the WAV file. This is the file type that is used to make all the ‘beeps’ and ‘boings’ that Windows 7 produces whenever you perform an action, such as emptying your recycle bin.

You can take a look at these files and change which ones are used by opening the Windows 7 Control Panel and double clicking on sounds. The sound quality of WAV files are excellent, but there is one huge problem that has prevented them from becoming useful on the Internet for anything other than short sound bites – such as the clips and quotes from your favorite TV shows that the Net is awash with. The problem is size.

WAV files are huge. MPEG Audio Layer 3

MP3 – or MPEG Audio Layer 3, to acknowledge its full title – is basically a file format which produces near-CD quality, in about one twelfth of the space of a WAV file. It was developed by the Moving Picture Experts Group – hence the acronym – which was responsible for MPEG-1, MPEG-2 and the development of MPEG-4. There is no MPEG-3, as such, and the MP3 that we know is simply the file extension for what is one of three MPEG audio coding schemes (Layer-1, Layer-2, and Layer-3).

The principle behind MPEG is to provide, as its name suggests, more than just audio formats. How it Works

How Layer-3 decoding achieves such compression, without a huge hit to the quality of output, is quite a feat. Terms like ‘perceptual audio coding’ and ‘psycho-acoustic compression’ are enough to impress anyone, even if you haven’t a clue what they mean.

Essentially, the superfluous information is removed from the signal, and by superfluous we are mainly talking about all the frequencies that are beyond the range the human ear can pick up.

MP3 is not illegal, but copyright still applies to any piece of music, regardless of form. Therefore, the huge upsurge in MP3 files that appeared on the Net – mostly ripped from copyrighted audio CDs and converted to MP3 format – stepped on to the wrong side of the law and caused great consternation in the record industry.

Copyright is the one area that MP3 doesn’t address. There are alternative file formats that do take this into account, such as Liquid Audio, but they have failed to attract the same attention as MP3.

The number of MP3 files on the Internet is staggering. To get the best out of MP3 music, you’ll need a decent computer. Any Pentium class machine will suffice. You’ll also need a program to play your MP3 files. Windows 7 Media does a good job of that and is included in Windows 7/XP. If you fancy turning your CDs into MP3 music, you need a program called a MP3 Decoder.
