Query noise level in Android

Question

I want to develop a small Android app to measure the current noise level (probablyin dB). But I have no idea what to look for in the libs. I don't want to record the noise. Can someone give me a pointer what classes to look at?

Answer 1

I recommend looking in these classes:

android.media.AudioFormat
android.media.AudioManager
android.media.AudioTrack

We used them in the Blinkendroid audio package a short while ago.
