Audio spectrum Analyzer for Android.
I wrote this small (but potentially useful) Android app to experiment with and understand various features of the Android SDK, including:
- Pan and pinch to zoom
- User preferences
- Custom attributes
- View animations
- Audio subsystem
Files:
- fftLibrary: a library project containing the FFT code
- audioAnalyzer: A simple android app to excersize the FFT library
I'm making this available in the hope that it is useful. Stephen Uhler
