Highlights

  • Plots a live audio spectrum showing energy across the frequency range.
  • Renders a scrolling spectrogram that tracks frequency content over time.
  • Works from the Android device's built-in microphone input.
  • Distributed under the Apache-2.0 license by woheller69.

Über diese Anwendung

Audio Spectrum Analyzer displays the frequency content of incoming audio as it arrives. It offers two views of the same signal: a spectrum plot, which shows the distribution of energy across frequencies at the current moment, and a spectrogram, which stacks those readings over time so patterns and sustained tones become visible as bands. Both update live while sound is being picked up.

This kind of tool is used for checking room acoustics, identifying hum or resonance, tuning instruments and speaker setups, or simply seeing what a recording environment looks like before committing to it. The application is published by woheller69 under the Apache-2.0 license and is available for Android. Measurements depend on the device's own microphone and its response curve, so readings are best treated as relative comparisons rather than calibrated absolute values.
