Doppler + Air

Sound Particles Doppler + Air pairs two audio effects for creating convincing movement and distance in your mixes. Doppler recreates the shifting pitch, level and frequency balance of a sound passing a listener, making it useful for vehicle flybys, moving effects and cinematic transitions. You can set the exact moment of closest approach for picture sync, choose metric or imperial units, and work with microphone configurations from mono and stereo to surround and Ambisonics. Air focuses on the high-frequency absorption that occurs as sound travels through the atmosphere. Rather than relying on a basic low-pass filter, it models air dampening with location presets, custom settings and a visible frequency-response curve. This bundle suits sound designers, post-production editors and producers who want realistic spatial cues for dialogue, effects or experimental music. Formats include AAX Native, AU, VST and VST3.
