Music on this site is available in different formats for the following reasons.
When you click on a "play" button to listen to a song, a flash MP3 player "streams" the MP3 over a live connection. These files are formatted as 64 Kbps bit rate MP3s in order to help keep the sound file from "breaking up" in transit for those listeners who have slower internet connections.
As a registered site member, you can download any of my songs available here for free. The free downloads are the same 64 Kbps format as the MP3s you listen to here online. Membership is free and it only takes a minute to sign up.
When you choose to purchase a song, you will get an MP3 file formatted at either 128 or 192 Kbps bit rate. The higher bit rate provides enhanced sound quality that is becoming more popular with music buyers.
Of course, CDs provide you with the best listening experience with the standard for CD audio at 16-bit/44.1kHz format. When you purchase my music collection CDs or purchase licenses to use my music in your productions, you will receive the songs as either CD-Quality WAV files or as CDA (CD Audio) files.
