Encoding Format:

MP3: Shrinks sound data without sacrificing sound quality.
ADPCM (Adaptive Differential Pulse Code Modulation): Produces a lower bit rate by recording the differences between samples.

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.

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.

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.

Select an option from the list. 128 kbit/s is a typical selection; 256- 320 kbit/s is considered near CD quality.
