This box lists the audio format attributes. The attributes are (from left to right):
Sample Rate in kHz Number of audio samples per second, or the fidelity of the audio recording.
Sample Size in Bits How much data to record for each audio sample.
Note An 8-bit sample size is possibly satisfactory for voice recording. Since using a 16-bit sample size doubles the size of the audio data you record, use it only if you must have the highest quality recording.
Mono or Stereo The number of audio channels to record. Mono means record one audio channel, Stereo means record two audio channels (right and left).
Note: Stereo is only useful if you are recording with a stereo microphone. Since using a Stereo audio format doubles the size of the audio data you record, use Stereo only if you know you are recording with a stereo microphone.
Data Rate The data throughput of the audio stream in kilobytes per second (kbps).
Note: For most of the attributes, the higher the number, the higher the quality of the recording and the larger the movie file.
