## Description

Audio Spectrum Analyzer Pro is a powerful real-time audio analysis extension for Chrome. It features an octave band Real Time Analyzer, FFT plots, and supports linear and log scales, with FFT sizes up to 16384 and a variety of window functions. It also provides max/min tracking for any selected frequency to help you pinpoint spectral details.

It includes pre-calibrated profiles for device-integrated mics and AirPods/AirPods Pro for safer, more accurate measurements. External microphones (wired or Bluetooth) are supported, and it supports Noise Rating and Noise Criterion metrics for reliable sound assessments.

## Review summary

The app is praised as a strong real-time spectrum analyzer with an ad-free, easy interface and solid live-performance use. However, reviews consistently complain about subscription barriers and paywalls, significant iOS 16 compatibility and performance problems, licensing/trial friction and device-compatibility issues, mic-only input limits (no file import or external input), and graph/UI quirks that hinder precise frequency pinpointing.

### Pros

- Real-time spectrum analysis with clear live visuals that aid frequency identification and live sound work.
- Ad-free and easy-to-use interface, especially in the free form offered.
- Highly regarded by professionals and performers, often preferred over built-in mixers for live sound.
- Multiple graph types and measurement options that remain usable in the free tier.
- Helpful for identifying pitch and tuning during performances and sound checks.

### Cons

- Subscription/paid model with features behind a paywall and frequent prompts, reducing perceived value.
- iOS 16 compatibility and performance problems, including slow processing, freezes, and UI glitches (dynamic island issues).
- Trial/licensing friction and device compatibility concerns (cancellation/restoration issues, Mac vs iPad limitations).
- Input/output limitations in practice (mic-only input; no upload or external audio input support; unclear mic calibration options).
- Graph/UI accuracy and usability problems (numbers obscured, axis orientation issues, difficulty pinpointing frequencies, limited zoom/scale).
