What is MP3?

MP3 has become the commonly used format for converted audio files to be stored and transferred over the internet. These files take up much less space than the audio format used on, for example, a CD player.

Bandwidth and file size - An important fact to understand about MP3 files is that they can be recorded different bandwidth to produce different sounding and performing files. Recording at a low bandwidth produces smaller files with a telephone-like quality. Recording at a high bandwidth to produces a fairly large file with much higher sound fidelity. The smaller the file, the more quickly it streams or downloads.

You will note that some of our library offers you a choice about which bandwidth to download or stream. If you have a fairly slow connection or older computer, we recommend that you use the lower bandwidth in order to avoid a long delay on downloads. Please be aware, also, that many of the archival classes in our data base were NOT recorded with professional equipment. In these cases you may not notice a significant difference when you download at the higher bandwidth. The file only reproduces as much quality as there is in the original recording.
