"title": "Amazing Audio Tool",
"body": "Update May 2, 2023. I have been an RTA audio user since February 13, 2017. Just recently I have found the need to update my evaluation and give the developers a chance to fix things. But overall I’m extremely pleased with how the developer has kept increasing the functionality of this great application. To this end I am submitting these areas that need to be updated and rectified. >>>>>>>>>>>>>>>>> iPad mini 5 generation, iOS 15.4.1, iPad 9, iOS 15.4.1, iPad 7, iOS 15.4.1. iPhone 12, iOS 15.4.1 On all iPads including the iPad mini, I am unable to export files and I am unable to delete files. Only on the iPhone 12 am I able to export a file, delete files. Please fix these bugs, thank you. >>>>>>>>>>>>>>>>>> RTA audio Pro has been an amazing app. Lets you see the sounds you hear, even the low frequency ones. The only reason I don’t give it a five star review is that I can’t export what I see as a movie video.",

"title": "Thx for s great app",
"body": "I’ve been using the app for over 2 years. I’m an audio engineer in a large mega church system. I have access to a lot of cool gear and I’m always on my iPhone as we use a group messaging app during services. And since I have my iPhone open the ease of this app is awesome. The new upgrade is a good one. This app works for me in a FOH situation every-time. Being responsible for an 1,100 seat auditorium for several services a Sunday I report back to the staff on Mondays my db levels and what frequencies were getting up there. It’s a great tool in my tool bag. Thx for the app. It works for me and our church campuses.",

There is no way to allow microphone access if the app no longer request access. The app performed phenomenally up until this issue appeared. Is there anyway to resolve this?",
