Sound Analyser PRO

Sound Analyser is an audio app that transforms your Android device into a powerfull audio spectrum analyser with spectogram and 3D waterfall

- high dynamics with 20 FFT analysis per second
- auto or manual scale
- log (dB) or linear scale for the amplitude
- log or linear scale for frequency axis
- selectable FFT window: flat top, Hanning or rectangular
- zero-padding for better FFT frequency resolution
- selectable sampling frequency, up to 96000 Hz (supported frequency depends on the device)
- performance factor for slow devices
- zoom on the frequency and time axes (drag the axis to zoom)
- amplitude scale zoomable
- multitouch zoom
- cursor on the spectrogram with or without frequency sound reproduction
- auto-peak cursor
- auto calibration method, using the in-built speaker. The calibration file can be manually edited with a simple text editor
- portrait and landscape display
