Hi Im a bit of an experimenter I have plenty of time on my hands but not much money.
Im into internal combustion engines.
I am currently interested in Ruben's Tubes.
I have some sound waves to try on one let me know if you have a working one, I would like to see the affects of my engine sounds.
I have attached a sample of my engine going through the gears with the bass boosted by 18 dB and mid to HF cut.
12345 18 dB bass boost.mp3
I can raise or lower the frequency to suite the length of the tube.
