Option	Description
Name	Assign a meaningful name to the Audio Formats. For example, select Telephone Quality includes 11.025kHz, 8 Bit, Mono attributes.
Save As	Save an audio recording profile.
Remove	Remove an audio recording profile from the dropdown list.
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).
