OK I've actually slept simce my rock and roll days, but IF I remember correctly, white noise has equal energy per hertz which means that it has a rising frequency responce plot as frequency rises. Sound systems are more properly equalized with "pink" noise which is white noise filtered to yield equal energy per octive or a flat frequency response.
If you set up EQ with white noise you will have a "hotter" high end than you might want. Does the internal generator create pink or white noise? Bill AD5OL >>> "Tim Ellison" <[EMAIL PROTECTED]> 11/15/05 11:47AM >>> I was setting the receive EQ this morning and had an idea that I wanted to share with the Flex-Radio virtual neighborhood. Back many moons ago when I was much younger, I played in a rock band (for all the reasons you would join a rock band) and one of my jobs was to help the sound man set the final EQ specific to the speakers we were using and the geometry of the venue we were playing. We did this with a white noise generator and an audio spectrum analyzer. My thought was we have most of those components already in the PowerSDR application. If you added a white noise generator you could direct the output to your speakers and while using your microphone to measure the output, you manually (or with an automatic software routine) adjust the receive EQ until you flat line the response. This would allow you to compensate for room acoustics and non-linear speaker response.
