I have 10 sound files saved in wav format that I'm trying to normalize to the same SPL level. Each is pink noise of a certain frequency range. Using a normal "normalize" function in Cool Edit only normalizes the peak value, but I need the SPL to be equal across all files. I'm guessing I'll need to amplify each wave file by a certain amount to get them to all reach the same value (-3 or -6dB I'm guessing). I was going to do this by trial and error, but I'm hoping that there is an easier way...

Here are the values for what I have:

Band 1: 50hz / -16.2dB
Band 2: 100hz / -22.94dB
Band 3: 180hz / -22.8dB
Band 4: 350hz / -22.16dB
Band 5: 700hz / -22.27dB
Band 6: 1.30khz / -22.52dB
Band 7: 2.50khz / -22.37dB
Band 8: 5.00khz / -22.48dB
Band 9: 10khz / -23.2dB
Band 10: 18khz / -24.46dB
