Apple Workgroup Server 8150/110 - Manual (Page 130)

3 Click the icon that represents the source of sound output.
About the sample rate: Most of the time you will not need to change the
sample rate. Use the Rate pop-up menu to change the sample rate only if the
sound you wish to play was recorded at a sample rate different from the current
setting. For instance, if you play a QuickTime movie containing sound recorded
at 44.1 kHz, set the sample rate in the Rate pop-up menu to 44.1 to hear the full
quality of the sound. Increasing the sample rate slows performance.
m Do not set the sample rate higher than the sample rate of the sound you are
playing, since this slows your server’s performance without improving
sound quality.
m Do not change the sample rate if the Play-Through option is selected.
m Do not change the sample rate for sound coming from a device connected to
the sound input port.
The other options cannot be changed. If you use a program that provides
sound recording in mono format, you can use its mono setting.
4 Close the Sound control panel.
Recording an alert sound
Although your server can produce stereo sound, the server records alert sounds
in the same way as other Macintosh models: in 8-bit mono sound, at a sample
rate of 22.254 kHz. This makes the alert sounds you record compatible with all
Macintosh computers. For instructions on recording a sound, see the “Sound”
topic of Macintosh Guide, available in the Guide (
h) menu.
