MP3 or OGG

Channel: Selects a channel, such as mono or stereo. A stereo signal consists of two separate audio channels, while a mono signal has one. A single audio data file may contain information for one, two, or in some cases, more audio channels. This means that stereo produces better quality sound.

Bitrate: The audio bitrate setting defines the audio quality of the MPEG output. A higher bitrate setting produces better quality, while at the same time resulting in a larger file size. On the other hand, a lower bitrate produces a smaller file size, while the quality is lessened.

Priority/Quality: For MP3, select quality from drop-down list; 0 = best quality, 9 = fastest speed

Conversion Frequency (Hz): Select the frequency, or the number of times an event repeats, or number of vibrations produced by a signal or sound, in a given period. Frequency is measured in Hz. One Hertz is one cycle per second. In Blaze Media Pro, the settings are listed in kHz, or kilohertz.
