Product Description
The Ammann CH-4900 represents robust Swiss civil engineering built for high-impact compaction and heavy road construction work. Driven by a heavy-duty industrial diesel engine, this soil compactor sound library delivers a dense, low-frequency acoustic profile. Its sonic footprint is characterized by deep engine chug, heavy hydraulic pump whine, low-end chassis vibration and resonant mechanical metalwork. It provides an authentic industrial rumble ideal for construction vehicle audio design, urban infrastructure projects, video game machinery setups or post-production soundscapes requiring heavy-duty earthmoving equipment.
Whether you are designing audio for a realistic construction simulator or expanding a specialized collection of heavy machinery, the CH-4900 offers ultra-clean, high-resolution source material capturing essential operational perspectives and mechanical details.
Industrial diesel signature: Captures the heavy diesel combustion hum, steady hydraulic drive whine, structural vibration and front/rear acoustic divergence characteristic of late-90s Ammann compaction machinery.
High-definition sonic detail: Recorded at 192 kHz using a shotgun RØDE NTG1 and stereo Shure VP88 setup to capture sharp mechanical transients, ignition tumblers, metal latch clatter and heavy engine panel movement with high clarity.
Dual-perspective engine tracking: Features distinct Front and Back recording angles for revving, startup, idling and shutdown sequences, allowing precise spatial blending between exhaust output and front radiator/engine bay focus.
Mechanical foley archive: A thorough selection of exterior mechanical recordings documenting the Ammann CH-4900: including heavy steel engine hood releases, key ignition tumblers, horn blasts and industrial light switchgear.
