What is a Spectrogram?

Every signal is a combination of unique frequencies, and can be disassembled into its frequency components. ("Frequency Spectrum")

A Spectrogram is a technique that is used in Audio Analysis (Spectral Analysis) to see the real-time behaviors of signals. It plots the frequency components of the signal over time.

The bar on the left shows the frequency (in [Hz]) and the color is the intensity of that frequency.

Why AndroSpectro?

For non-techies - AndroSpectro is the simplest spectrogram app available. Just press the "Play" button. Feel free to Zoom-in/Pan using multi-touch gestures. You can also easily set the Maximum level or press 'auto' for auto-leveling.

For techies - AndroSpectro gives you control over every parameter you can think of. Display up to 3 minutes of continuous recording history and save as an image for later viewing.

For mega-geeks - Export the raw Spectrogram data to Matlab for further analysis. Your phone becomes your handheld input device for advanced audio analysis. (We wish we had it as a student)
