Spectrogram

A spectrogram is a visual representation of the spectrum of frequencies of a signal as it varies with time.

PreviousDecode SSTVNextbinary-exploitation

Last updated 1 year ago

Online Tools

  • Display a spectrum of signal amplitudes on different frequencies. Upload audio file like .wav or .mp3, .ogg.

Using Audacity

Audacity is an audio editor which also can be used for decoding signals in audio files.

  1. Open an audio file in Audacity.

  2. Click the name of the file at left menu (which contains the reverse triangle icon).

  3. In the drop-down menu, check Spectrogram.

  4. If you want to edit advanced settings, click Spectrogram Settings in the menu and edit values.

  5. Click Play button.

Using Inspectrum

Using Rtl-433

# -A: Pulse analyzer.
rtl_433 -A <file>

is a radio signal analyzer for .cf32, .cf64, etc.

decodes radio transmissions from devices on the ISM bands.
