MP3 players play many different formats of music and files. Although not all files that you would want to put on your MP3 player will come in these formats so you will have to change them to these kinds of files. Now there are different ways but the most popular way is to use an Encoder.
This changes the code of the file so you can become a new format and you will be able to use it on your MP3 player. Although there are many different kind of MP3 encoder on the internet but the most popular is the LAME MP3 Encoder. This encoder was started in the mid 1998. Now there is only 4 members left working on this project although it has been the best MP3 encoder that works at mid-high bit rate and also at VBR. This LAME MP3 encoder was created thanks for the dedicated work of all its developers.
Also, not only that it's very useful and can work quickly, it is also the most actively developed. So basically there are different kinds of encoder that encodes different kind of files. If you own a MP3 player, it is best to find a MP3 encoder. This will allow you to play all your other type of files on your MP3 by just simply converting them. It is best to find a fast one as you do not want to wait a long time for the files to get encoded so you can quickly enjoy your music on your MP3 players.
These MP3 players include the iPod created by Apple. A popular music file format is the WAV but not many MP3 players support this format so you may use an encoder to convert the WAV files to a MP3 file so you can quickly put it onto your MP3 player to play the music. Also, not just changing the file format, you can edit the music files as well. You can change many parts of the music file so it fits your need by using a simple MP3 encoder. Although like written in the first part of this, there are many different types of MP3 encoder and if you're trying to find some MP3 encoders, you may choose the all popular LAME MP3 encoder, BladeEnc and many more of these special MP3 encoders. Some of these encoders are not free and requires and ISO which can be bought since ISOs are on CD and DVDs. There are illegal versions of these programs and since your need a CD key to work these you can also find a CD generator but this is not wise and it is still best to find a free one on sourceforge like the LAME MP3 encoder.
So now you know how to find them and what they do, next time you need music, just convert it through an MP3 encoder and also you would be able to edit music files using a MP3 encoder by changing many different aspects of the music file.
