You can use a tone generator program to make whatever frequency, duration, and waveform that you want, and then save it as a .WAV file and burn the file to a CD. I like NCH Tone Generator, because it's simple and flexible. It does sine waves, square waves, triangle, sawtooth, pink noise and white noise. It will also do sweeps, which are nice for tracking down squeaks and rattles in panels. Here's a link to the program: https://tinyurl.com/3yxfd Hope this helps, Scott Gardner

Do you hook the computer to the car to use the tone generator? I couldn't find any "save-to-.WAV" feature in WinISD. Scott Gardner

In the Parts Express Cat. there is a device called a Minirater made by Neutrik. Fits in your hand and will do sine wave, square wave, white noise, pink noise plus sine sweeps. The cool feature is it's LCD display that shows you what you are outputting, unlike many units which just have dip switches. The output levels are displayed in dBu, dBv or V. It is $235.00 however I have yet to find anything better. Goodluck!

The Ultra tool is called SMART which is quit a powerfull Acoustic Program. Similar to the Meyer Sound SIMM ($10,000 plus 2 weeks of classes) used for live sound. This software will show you in real time what the Ref mike is detecting compared with the input signal. The result shows what is being reproduced from the speakers and what effects the vehicle or room is having. It works with music or pink noise. Also very helpfull for setting or finding delay times and SPL. The program will store results and graphically overlay previous measurments. Just very cool. My copy is company owned and have no idea what the current cost is.

Using Pink from a laptop has not worked as well as a dedicated signal generator. A Minirater or a Goldline PN-3 works. With a laptop or computer you are limited to the freq. responce of the card and the quality of the recorded file. As you playback other wave files, eq might be added or subtracted which could throw off everything. A dedicated unit is more consistant and repeatable which is the basis for the ideal Reference Signal. A week, month, year later a dedicated unit will have the same level and signal, priceless for serious competitors!
You can do 150db in your car? I get 110db 100 feet away, and have 25,000 people singing along. Loud is easy, making it sound good, that hard and rewarding! You can't recone your ears!!
