What a huge help this app is

Used with iPad mini. Ran pink noise to do the best I could to flatten the sound. What a difference this made! I can see areas that need improvement but I need DSP. For now this works! Thank you

Does not work on MQDY2LL/A iPad Pro with iTestMic 2

The app keeps saying “Accessory found iTestMic 2” then “Accessory removed iTestMic 2” and repeats until the mic is removed from my iPad Pro. Sometimes it just crashes or freezes on my iPhone 12. Both have latest IOS.

Great tool

A great app for the price. Very good comparison when using the inbuilt iPhone microphone to a dedicated RTA mic.
Easy to read screen and easy user functions.
