The Little Labs IBP Phase Alignment Tool is designed to eliminate the hollow, comb-filtered sound that occurs when combining out-of-phase or partially out-of-phase audio signals. It provides precise control over phase relationships, allowing audio engineers to address phase issues that commonly arise when blending multiple microphones or combining direct and miked sources. This tool delivers a clean, natural sound by aligning audio signals without compromising tonal integrity.

Beyond its corrective capabilities, the IBP serves as a creative instrument for shaping audio phase as a unique tonal element. It is useful in a variety of recording scenarios, including multi-mic drum kits, acoustic guitar and vocal combinations, and split guitar amp setups. The phase alignment process is simple and fast, enabling users to experiment with phase relationships to enhance the overall mix and improve clarity and depth.

The Universal Audio version of the IBP is optimized for digital audio workstations, featuring a continuous Delay Adjust control that expands phase alignment options in the digital realm. It offers flexible phase adjustment between 0° and 180°, a Phase Center switch for frequency-dependent phase control, and individual bypass options for precise workflow management. This combination of features makes the IBP a powerful and intuitive solution for both fixing phase problems and creatively manipulating audio signals.
