Depending on the format you are converting to you can select different frequencies, channels, bits per sample, and bitrates. These are described below.
Frequency: Frequency is the number of times an event repeats (number of vibrations produced by a signal or sound) in a given period. Frequency is measured in Hertz (Hz). One Hertz is one cycle per second. In Blaze Media Pro the settings are listed in kHz (kilohertz).
Channels: Mono or Stereo? 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; therefore stereo produces better quality sound
Bits per sample: The more bits used to store each sample in digital form, the more thorough the original signal's amplitude can be represented. This in turn may result in higher audio quality in the system. However, the more bits used per sample, the larger the digital audio data size will be.
Bitrate: The more bits used to store each sample in digital form, the more thorough the original signal's amplitude can be represented. This in turn could result in higher audio quality in the system. However, the more bits used per sample, the larger the digital audio data size will be.
