Comments on AudioTool for Android

★★★★★ Tim Rolufs Sr. · Mar 18, 2024

Excellent app, even better with the Dayton audio imm-6 external microphone. Well worth the price. I used it at a local outdoor concert to measure the frequency ranges of the instruments being played and the spl of the concert was 105 near the speakers and a constant 100 at my seat. I look forward to using it in my basement, car and my son's truck.

★★★★★ Kevin Wilks · Feb 25, 2024

This tool is a lifesaver. Works perfectly on the SONY XPERIA Z. ****update 2024*** holy macaroon, been using this tool for over a decade now, and I cannot express in limited words how invaluable it has been to my progression, efficiency and effectiveness throughout the years. I'm on the S24 Ultra now, and it performs flawlessly for PA diagnostics (generator), RTA and general level monitoring.

★☆☆☆☆ Geocentric · Apr 1, 2025

It's not accurate at all from 30 HZ to 70 HZ or so. Reads extremely low from 30 to 60hz range compared to spectroid with same mic and position. My 30hz isn't almost 30 decibels less than peak bass. For speakers and earphones it is saying it has basically zero low end. High resolution set on "flat" and it's way off until around 70hz. Not my mic or me at all. Spectroid is more accurate and it's free. What is going on with high-end reading? Can't tune bass with this at all. Used calibration file too

★☆☆☆☆ M W · Jun 27, 2023

I have a Dayton Mic. A Motorola Stylus phone. I have no Audio Tool folder on my phone. I can only move my Calibration File to internal storage on my phone, I have no way of getting the Audio Tool Folder into my internal storage. I've saved files on the Audio Tool app but this does not help me find a way to move my calibration into Audio Tool. After Using 1/3 Octave Calibration I am unable to Load Cal. If I can't load my Cal File I'd like my money back please.
