About This Tool

The Radio Analyzer is a comprehensive online tool for analyzing radio signals and audio frequencies. Upload WAV, MP3, or other audio files to visualize the waveform, perform Fast Fourier Transform (FFT) analysis to see the frequency spectrum, and measure key signal characteristics including signal-to-noise ratio (SNR), bandwidth, dominant frequencies, and amplitude distribution. The tool provides both visual representations and detailed numerical metrics for radio engineers, hobbyists, and audio professionals.

Frequently Asked Questions

Find Quick Answers

What audio file formats are supported?

The tool supports WAV, MP3, OGG, and FLAC formats. For best frequency analysis results, use uncompressed WAV files with high sampling rates.

How accurate is the frequency analysis?

Frequency accuracy depends on the audio file's sampling rate. The tool performs FFT analysis with configurable resolution up to 8192 points for detailed spectrum visualization.

Can I analyze live radio streams?

Currently, the tool analyzes uploaded audio files. For live stream analysis, you would need to record the stream to a file first, then upload it for analysis.

What signal metrics are calculated?

The tool calculates signal-to-noise ratio (SNR), bandwidth (3dB and 10dB), dominant frequencies, total harmonic distortion (THD), peak amplitude, RMS amplitude, and crest factor.
