Quality Analyzer

Audio analysis for iOS with real-time IEC 61672-style A-weighting, a live spectrum analyzer, and detailed file analysis. Monitor reference sound-level estimates across the displayed 30-110+ dB range, subject to the microphone and calibration limits of the device. Designed for DJs, sound engineers, and producers who want immediate audio feedback. Analyze files using Laptop & PA System translation scores, perceptual metrics such as Warmth, Clarity, Dynamics and Spaciousness, plus spectral analysis and a detailed spectrogram. Built on the same mastering engine as Instant Mastering, it helps you estimate how a mix may translate before you play it. Quality Analyzer is not a certified sound-level meter or a substitute for calibrated safety equipment.

Quality Analyzer was born from the need to understand what makes audio sound professional, and to test it before it reaches the audience.

As a DJ and producer, I needed to know: Will this track work in a club? How will it sound on a laptop versus a PA system? What does the mix actually need?

Traditional audio analysis tools felt too complex for quick checks. I wanted something that could provide immediate, practical feedback using A-weighting, real-time dB estimates, and perceptual analysis that is easy to understand.

Quality Analyzer uses the same core engine as Instant Mastering, sharing technology and insights. Together, they form a complete workflow: analyze first, then master. Two apps, one mission: better-informed sound decisions.

Whether you're checking reference sound levels, estimating compatibility before a gig, or analyzing a finished mix, Quality Analyzer gives you practical information to review. ⚡
