Frequently asked questions

General questions

What is MP3?

MPEG-1 Audio Layer 3, one of most popular audio formats. It compresses standard audio tracks into much smaller sizes without significantly compromising sound quality. Since the MP3 file format has no mechanism for copyright protection, it is not widely used by commercial music data distribution sites.

What is WMA?

Windows Media Audio is an audio format developed by Microsoft Corporation in order to distribute CD-quality music even via low-speed communication lines such as ISDN. WMA employs a more efficient compression method than MP3, and has the advantage of reducing the bit rate with the least loss of sound quality (80 kbps encoding results in almost the same sound quality as MP3 encoded at 128 kbps). WMA is a format suitable for portable players with limited memory. WMA also provides the mechanism that allows music files to contain encrypted data such as copyright-protection information in them in combination with Windows Media Rights Manager.
