About this app
Measure the frequency response of your audio system using your phone's microphone or a peripheral microphone.
How it works:
The app plays a logarithmic chirp sweep from 20Hz to 20kHz through your speakers while recording with the microphone. It then analyzes the recording to show how your audio system performs across the frequency spectrum.
Features:
Stereo mode measures left and right channels separately
Results normalized to 1kHz reference
Average multiple runs for more accurate results
Save graphs as images or export raw data
Measurement history with comparison view
Support for microphone calibration files
Fullscreen landscape graph view
Best for:
Comparing left vs right channel balance
Identifying problem frequencies or dead drivers
Quick sanity checks on audio equipment
Keep in mind:
Results depend on your phone's microphone, room acoustics, and measurement position. This is a practical tool for relative comparisons and troubleshooting, not a replacement for professional measurement systems.
