Correlometer is an analog-style stereo multi-band correlation meter designed to enhance phase analysis in audio mixing. Inspired by the correlation meter found in the PHA-979 phase-alignment plugin, it provides detailed insights into phase relationships across multiple frequency bands. This tool helps audio engineers detect out-of-phase elements that can affect the clarity and coherence of a mix, particularly in the mid to high-frequency ranges where such issues are often hard to hear but impactful.

Unlike traditional broadband correlation meters that offer an overall view of phase alignment, Correlometer breaks the audio spectrum into 4 to 64 adjustable bands, allowing for precise identification of phase problems within specific frequency areas. This multi-band approach is especially useful for tasks such as phase and time alignment of bass and drum pairs, guitar microphone and direct input combinations, or stereo recordings captured with two microphones. Its adjustable band quality factor and averaging time give users control over the selectivity and responsiveness of the correlation measurements.

Correlometer integrates seamlessly into any workflow with features such as side-chain input for comparing separate audio sources, zero processing latency, and support for all sample rates. The resizable user interface adapts to different screen sizes and includes multiple color schemes along with Retina and HighDPI support, ensuring clarity and ease of use. This plugin offers a reliable and detailed solution for engineers aiming to optimize phase coherence and improve mix clarity.
