Spectrogram APK for Android

Spectrogram is a free multimedia application designed for Android devices that provides users with an advanced spectrogram viewer for time-frequency analysis. This application offers extensive customization options, allowing users to adjust the FFT resolution from 32 to 65536, select various window types, and choose different color scale types. Additionally, it includes several interface modes to enhance user experience and adaptability to different use cases.

One of the notable features of Spectrogram is its ability to reduce spectrum leakage through nine distinct window algorithms. The app is equipped with a fast pause and resume button, which facilitates quick analysis, and offers an option to keep the screen active, overriding the device's screen timeout settings. However, users should be aware that the amplitude value is not available due to potential inaccuracies without proper device calibration.
