4 Troubleshooting Your Personal Workstation and Using the Setup Program
If Your Personal Workstation Has an Audio Problem

Audio Input from the
Microphone is Too Low,
or No Audio At All
Check that the microphone specifications meet the requirements of the
16-bit sound components. The microphone should be a 600-ohm
dynamic type.
Humming Noise
If the power grounding of your audio components is inadequate, a
humming noise may be generated. This may happen if your Personal
Workstation is connected to a hifi system. Plug all devices into adjacent
power outlets (outlets within 5 cm / 2 inches of each other), or use line
filters.
Occasional Crackles
When Playing Back
Sounds
These crackles are usually the result of your Personal Workstation being
unable to transfer audio samples within the required time. A solution is
to use a lower sampling rate. Recording and playing back at 22 kHz is
less demanding upon system resources than recording audio at 44 kHz.
The Personal
Workstation Hangs
While Recording
Uncompressed digital audio can eventually fill your hard disk. For
example, one minute of stereo sound recorded at a resolution of 44 kHz
will occupy about 10.5 MB. Before recording, check that there is enough
free space on your hard disk.
Data compression can reduce the space required. The A-law and
µ
-law
hardware compression used by the audio interface enables the
sampling of sound at a resolution of 16-bits, but it generates the same
quantity of data as an 8-bit sample.
