Audiobel: Professional SPL

Works great for ambient noise levels including highest and lowest levels indicators and recording ability for later playback.

I love this app and use it for the simple tasks that it provides. But I do think it needs more features revolving around audio. The features I think you should add are: spectrogram. Now this being one thing that I would like to see is just something that I would use a lot.

This App looks pretty solid. I've wanted something like this for a long time and am excited to test it with a neighborhood issue where a commercial property has installed an alarm that wakes the neighbors. The development work on this App is greatly appreciated!
