Sample Frequency	See Bit Rate and Sample Frequency for all settings. Frequency at which
	the audio is sampled at the encoder. Range 8–48 KHz. Shown for
	Audio Rate1 only. Audio Rates2 and 3 share this common value. If
	Audio Rate2 or Audio Rate3 s enabled, the Sample Frequency is
	automatically set to 44.1 KHz.

Audio Rate2	Use to configure multiple bit rates. Check Enabled to display
	configuration settings for Audio Rate2. Once enabled, AudioRate2 and
	AudioRate3 are available for selection on the Multicast, Server, and
	Archiver pages. If selected on those pages, an error will display if you
	attempt to disable them on this page.

Audio Rate3	Use to configure multiple bit rates. Check Enabled to display
	configuration settings for Audio Rate3.

Bit Rate and Sample Frequency

The following are the allowed combinations of Bit Rate and Sample Frequency when Audio

Channels is Stereo or Mono (left only) or Mono (L+R).

For example, if you configure the archiver for a two-hour duration, and there is a disruption that forces it to close one file and open another, the time in file1 plus the time in file2 will equal two hours regardless of how long the disruption lasted. When the archiver is configured with a duration and a file size set to 0 Maximum, the archiver limits are 4 GB or 12 hours, whichever comes first, no matter how many disruptions occur and how many files are created firmware Windows Media Archiver -- Slot1the C drive.
