Computer Assisted Radio Monitoring
Last month I introduced the computer sound card and looked at how it works. Most sound cards perform two functions, which is to produce sounds with a wave file and sample sounds using a digital signal processing circuit.
It is the digital signal processing (or DSP) capability of a sound card that is used by many software programs for use by radio monitors. These software programs can do many things, such as filtering audio bandwidth, reducing noise and interference, demodulating signals, and digital recording of sound.
In this month’s column I’m going to be looking at the proper installation and configuration of the Sound Card in a Personal Computer next month. I’ll be introducing some more monitoring software that is free on the Internet.
Plus, I’ll have some letters than too. I have to
report that there was a small revolt on the part of the Mac owners out there
who insist on being represented in this column. So be it.
Sound Card Installation
There are a multitude of sound cards available
for the Personal Computer today, with multiple models manufactured by many
different companies. The reason for having so many cards available is due to
the many different types of applications that people wish to use these cards
for.
