Comments on AudioTool for Android

★★★★★ Great hifi tuning tool. Using with Dayton Audio imm-6 mic with calibration file. Stays set unless you change it. Enter mic serial on DA site and download xxxxx.txt calibration file. Rename from xxxxx.txt to xxxxx.cal. Move file from Download folder into the Audio Tool folder. In the app go to "Menu" and select "Load cal". Choose the xxxxx.cal file. n.b. If you do not see the Load Cal menu entry, click on "Use 1/3 Octave Calibration". Re-opening the menu will then show the button.
★★★★★ RTA is useful with dayton IMM-6. Had to remove a star because of inconsistent results with spl offset. May be compression on mic. I am not exactly sure why spl is not lining up with another spl meter.
★★☆☆☆ 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
★★☆☆☆ 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.
