Full product details

Sound levels are shown across the 30-110+ dB range, within the limits of the device’s microphone and calibration. For files, you also get perceptual metrics (warmth, clarity, dynamics and spaciousness), spectral analysis and a detailed spectrogram. The app is no 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. ⚡
