Format

Select the audio format for a new recording profile. Currently the only option is PCM (Pulse Coded Modulation), which is an uncompressed audio data format.

Attributes

  For most of the attributes, the higher the number, the higher the quality of the recording and the larger the movie file.

The attributes include (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.

  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).

  Stereo audio format doubles the size of the audio data you record, only use Stereo only if you record with a stereo microphone.

Data Rate
The data throughput of the audio stream in kilobytes per second (kbps).
