Iceberg Audio is a Dublin-based independent audio software company that develops virtual instruments and effects plugins for music producers. Its flagship product is The Sub, a dedicated sub-bass instrument plugin designed and developed by producer/sound designer Davide Gubitoso and developer Philip Mackenzie, built around a custom drive algorithm aimed at generating low-end for electronic, hip-hop, and pop production.

The company's catalog extends beyond The Sub with Sub Cut, an automatic low-cut EQ that adapts its filtering to the input signal, and Beatgrader, a multi-effect plugin. A library of expansion packs for The Sub — including the 808 Box series, Analog Heat, Fuzzy Waves, Nuclear Booms, Elements, Warm Pickups, and Urban Soul — adds preset and sample content in a range of sonic styles.

Iceberg Audio's plugins run as VST3, AU, and AAX on macOS and Windows and are distributed through the company's own site as well as retailers like Plugin Boutique. The brand positions itself around minimal, streamlined interfaces and task-specific tools rather than deep, parameter-heavy synthesis environments.

Iceberg Audio has 15 products cataloged on Equipboard, including Expansion Packs, Synth Plugins, and EQ Plugins.
