First, we will need a short loop. Noisy sounds with some high-frequency content work well for this. We can then:<\/p>\n
\n- On DspBusSetting_0, create a new Bus and name it \u201cDistortion\u201d\n
\n- Add some DSP Effects such as Distortion and Chorus<\/li>\n
- Send Bus to MasterOut<\/li>\n
- Set Volume fairly low (e.g., 0.15)<\/li>\n<\/ul>\n<\/li>\n
- On BusMap For AISAC and Automation<\/em>, apply Distortion Bus to DspBusName2<\/li>\n<\/ul>\n

<\/p>\n
\n- Rename AisacControl_00 to \u201cAisac_ProjectileDistance\u201d<\/li>\n
- Create a Polyphonic Cue named \u201cProjectileWhizz\u201d\n
\n- Drag in looping projectile Material<\/li>\n
- Set Pan Type to 3D Positioning<\/em><\/li>\n
- In the 3D Positioning tab, set:\n
\n- Distance \u2013 Aisac_ProjectileDistance<\/li>\n
- Doppler Factor \u2013 4.00<\/li>\n
- Attenuation Distance Min \u2013 20.00<\/li>\n
- Attenuation Distance Max \u00ad\u2013 40.00<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

\n- \n
\n- Create new AISAC with two graphs set to:\n
\n- Name \u2013 \u201cAisac_ProjectileWhizz\u201d<\/li>\n
- Control \u2013 \u201cAisac_ProjectileDistance\u201d<\/li>\n
- Graph Type \u2013 \u201cVolume\u201d and \u201cBusSend2 (Distortion)\u201d<\/li>\n
- Create Fast Change<\/em> curves on each<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

With everything set up, we can experiment with different settings on the DSP Bus Effects. We can also swap out the Material for a different loop or even layer different loops together. Lower attenuation distance values will make the projectiles audible only when they are very close to the player, but larger values could make the scene sound too busy.<\/p>\n
Testing<\/h2>\n
Let\u2019s open up the Session View to test our audio system. We can drag our BulletWhizz onto Player1, open the Positioning 3D tab, enable Attached 3D Object on Player<\/em>, and offset the Source X-axis left or right of 0. Then, by dragging the Z-axis value up and down, we can simulate a projectile\u2019s motion through the air. Since an AISAC controls the Distance parameter, the DSP effect is automatically controlled by the distance between the player and the projectile. This means it sounds especially daunting as it nears the player.<\/p>\n","protected":false},"excerpt":{"rendered":"Introduction When designing for an FPS game, it is important to sonify threats to the player.
