For my Ball-rolling game project in Unity 3d, I needed to replace the temporary engine sound I used as a placeholder. I wanted to record actual rolling friction sounds that would be modulated by the FMOD autopitch function for a more realistic experience. After a bit of experimenting with things I had around the house, I decided on using the big red marble from an optical trackball. <\/p>\n

\nFirst, I tried the inside of a computer case. It had a nice resonance, but I had difficulty getting more than a half-second’s worth of rolling before it smacked into the side of the lid.<\/p>\nhttp:\/\/tungstenfilamentgroup.com\/blog\/wp-content\/uploads\/2014\/10\/trackball_experiment_metallid.wav<\/a><\/audio>\n

\nSimilar to the metal lid problem, I couldn’t get much of a good roll. I found I could rock it back and forth to sustain it a little longer, but this gave it a seesaw effect of pitching up and down. Note, that this was just a quick test recording I did with the air conditioning running, so the quality is not up to snuff.<\/p>\nhttp:\/\/tungstenfilamentgroup.com\/blog\/wp-content\/uploads\/2014\/10\/trackball_experiment_plasticlid.wav<\/a><\/audio>\n

A few days later, I took inspiration from the wall of death\/wheel of death motorcycle stunts<\/a>. I started looking for round surfaces that I could rotate the ball around the inside of, centripetally. <\/p>\n

The cake carrier gave me quite a few variations in tone. I could use the clear plastic part with or without the bottom lid for different effects. <\/p>\nhttp:\/\/tungstenfilamentgroup.com\/blog\/wp-content\/uploads\/2014\/10\/cakepan_examples.wav<\/a><\/audio>\n

The metal pot is one that I’ve used in the past for PVKII, to impart the voice of the Heavy Knight with a ringing, metallic resonance. Whether or not the bottom of the pot was damped help give some extra tonal possibilities to the pot as well. <\/p>\nhttp:\/\/tungstenfilamentgroup.com\/blog\/wp-content\/uploads\/2014\/10\/metalpot_examples.wav<\/a><\/audio>\n

The watering can didn’t end up working out very well for the ball-rolling project, but I did end up sampling it as percussion for the game’s music. Look for a new video of the game project shortly.<\/p>\n","protected":false},"excerpt":{"rendered":"
