Thanks. I can’t claim original credit. It was developed by a couple of Nashville engineer friends of mine. Dbx actually has a similar thing on a test disc they put out years ago. I like mine better. Longer recordings. Seems to be filtered better. I have ran both and had better luck with the custom one. I can tell you. It generates a much better sounding system result than full broadband pink noise.

Back in the 70’s UREI had a product called Sonopulse. It was basically the same idea but used pulsed tones. Idea was the tone was pulsed and then with a calibrated microphone feeding an spl meter the signal peaked and held. Pulsing tones is better especially in the LF range so as not to create standing waves. It was a great room tuning tool.
