LiquidSonics is a UK-based audio software developer specializing in reverb and spatial processing plugins for music production, film, and broadcast post-production. The company is best known for its Fusion-IR technology, a dynamic convolution approach that combines impulse responses with algorithmic modulation to capture the time-varying behavior of high-end hardware reverberation units and acoustic spaces more faithfully than static convolution allows.

The product catalog is built around several flagship reverbs. Seventh Heaven and Seventh Heaven Professional emulate the Bricasti M7 hardware reverb, with the Professional edition extending up to Dolby Atmos 9.1.6. Cinematic Rooms is a surround and immersive reverb aimed at post-production workflows, supporting channel formats from stereo through 9.1.6. Reverberate 3 is a convolution plugin oriented around impulse responses of classic hardware, while Lustrous Plates focuses on plate reverb emulation. Additional titles include Tai Chi, Illusion, HD Cart, and the M7 Link control utility.

LiquidSonics plugins are widely used in professional music and post-production environments, with the company noting credits on Grammy-winning records, Oscar-winning films, and Emmy-winning television productions.

LiquidSonics has 7 products cataloged on Equipboard, including Reverb Plugins and EQ Plugins. Their gear is featured by 6 artists, with the strongest followings in Electronic, Stage & Screen, and Pop. Notable users include Anthony Rodriguez, Hans Zimmer, and Madison Beer.
