What's a good Android app for recording lectures clearly, even from the back of a large classroom?

Microphone Amplifier by DOSA Apps seems promising. It boosts mic volume and has an interesting implementation of noise reduction.

As someone who attends quite a few talks and seminars, I'm always looking for ways to capture audio clearly. Microphone Amplifier looks like it could be quite useful in those situations where the speaker's voice doesn't quite carry. The app boosts the microphone volume, which is essential, but the integrated noise reduction is what really caught my eye. It's an interesting implementation, and I'd be curious to test its efficacy in a real-world lecture hall. I also appreciate that it offers cross-platform compatibility, as I often need to transfer recordings between my Android phone and my laptop for transcription and analysis. I could see this being pedagogically sound for students too, especially those who benefit from reviewing lectures multiple times.
