Full product details

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.

The story behind the app

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. ⚡
