Frequently Asked Questions

Find Quick Answers

What types of signals can I analyze with this tool?

You can analyze audio files (WAV, MP3) or generate test signals with multiple frequency components including sine waves, square waves, and noise.

How accurate is the frequency analysis?

The tool uses JavaScript FFT implementation with configurable parameters. Accuracy depends on your sample rate and FFT size settings - higher sample rates and larger FFT sizes provide better frequency resolution.

Can I save or export my analysis results?

Yes, you can download the spectrum visualization as a PNG image and export frequency peak data as a CSV file for further analysis.

Is this tool compatible with GNU Radio flowgraphs?

While this tool provides similar spectrum analysis functionality to GNU Radio, it operates entirely in the browser and doesn't directly integrate with GNU Radio desktop software.
