I'm looking for test frequencies to burn on a cd. I'm looking for a wide range to help test speakers, monitors, and equipment. Once I have the frequencies I'd like to make one each track and last for around 30 seconds. I'd also like to include a right channel test and left channel test. I can make all that once I have all the frequencies. I can also put it in a zip file for others if I'm able to make or find one.
