AudioUtil Spectrum Analyzer captures audio signals and analyzes them right on your phone in real-time. Screenshots of the display can easily be taken through the utility's context menu. Freeze the display by touching the screen, and drag to show a value readout. Adjust multiple parameters for each utility, like frame size, zero padding, window type, range, and themes to name a few. This app can be used with a 3.5mm 4-pole (TRRS) external microphone (non-USB), if supported by phone.
