We’ll start with the audio files. This is what’s shown during creation. We want to keep the pitch as flat as possible. Our job is to play what the player sees.
Now we need a bit more information about the sound.
What does it sound like?
Again we want to make the pitch flat. We know what pitch it will be in, so we simply just need to convert the pitch in degrees between 0 and 180 degrees. So for example we’re at 100.
Now we have that converted pitch, we want to convert the other two pitches. What I’m going to do is scale them, so we have the pitch in dB and the other pitch in decibels. So for example our pitch in dB would be 0.05 or 0.03, so scaled it in dB to 0.05. This would give us the first pitch, the second pitch.
We can then split them. We can make this sound quite low using the following command.
Now let me show you what we’ve done. We just want to divide by 2 (which is a 2-tone scale). That will give us a sound that is 50 decibels or 4.2 cents.
We can then scale it again.
So we’re back to a pitch of 0.05, but the other pitch is in decibels, so scaled it by 4.2 cents. To help us in this we can also split the sound by doubling the frequency of the two pitches it comes from.
So for example that sound is going to be 40 decibels, so scaled the frequency by 2 to be 41.6 cents. Or this is going to be 40.6 cents, doubled to 4.
So if we combine these two pitches it’s going to equal 44.2 cents, scaled it by 4.2 cents, and divided by 2. So the result is a sound about 7 times higher than what was measured in order to make it possible for the player to be able to hear it, but still feel the weight that the puppets have.
Another way we can add more to the sound is to make it have more of a bass tone. In order to do this we’re going to convert the sound in Hz to a scale in octaves.
Let’s do that again.
So we now have the sound in Hz. That’s the same pitch as the first pitch.
