What's new in Spectrum Lab 2.72:

  • Added support for PERSEUS (a direct sampling LF..HF receiver by Nico Palermo (IV3NMV) / Microtelecom .
  • Added the possibility to "play back" the contents of the spectrogram buffer, using an inverse FFT to convert the spectra back into audible signals .
  • Added the 'hard limiter' in the signal processing blackboxes.

Spectrum Lab is a software application designed to help users analyse the spectrum of an audio signal via the PC’s soundcard and apply audio filtering operations.

The layout is not very intuitive, so rookies may spend some time trying to understand the function of each dedicated parameter.

Spectrum Lab comes packed with several tools designed to help you analyse audio signals, such as a spectrogram, spectrum graph, amplitude bar, and correleogram.

What’s more, you can generate and decode digital radio amateur communication modes, edit the color palette of the spectrogram, zoom in or out, seek a position in the audio stream, as well as view the intensity of a signal, azimuth angle, and elevation.

Spectrum Lab lets you start and stop the audio processing thread, configure the audio and FFT settings, adjust the frequency scale, automatically generate old parts of the spectrogram when changes occur, switch between multiple viewing modes, and set the audio sample rate.

Other important features worth mentioning are represented by the possibility to scale the FFT sound, insert noise effects, detect signals, work with various filters for (e.g. FFT filter, I/Q processing), schedule actions, and use the built-in HTTP server.

During our testing we have noticed that the tool offers very good sound quality, and no errors showed up throughout the entire process.

To sum it up, Spectrum Lab bundles a handy set of tools for helping you analyse the spectrum of audio signals. To make the most out of every single built-in feature, you can check the help manual for detailed information about each audio parameter.
