Note: Windows Media Encoder has many bitrate choices, the following bitrates are meant to act as guidelines only.

Audio

Voice only

AM radio

            20kbps            - This is an excellent bitrate for broadcasts that are primarily talking. It can also be used for situations where bandwidth issues require a lower bitrate.

Music

FM radio

            32kbps            - This is the current industry standard for FM radio broadcasts. It will work well for any music broadcast, or as a higher quality option for voice broadcasts.

Music (higher quality)

            64kbps            - Using this bitrate will provide a higher quality broadcast that works well for delivering near-CD quality music.

CD quality

MP3 quality

            128kbps          - This is generally the highest audio bitrate you should use. It will deliver excellent quality. Note: You should compare a 64k broadcast to a 128k broadcast, as many people do not feel the slight increase in quality is worth doubling their bandwidth usage. This is a personal preference decision.
