Spek is free software available for Unix, Windows, and Mac OS X. It Supports Popular lossless audio files formats, uses multiple threads for faster analytics, ultra-fast signal processing, and a high n number of frequency bands for the best spectrogram quality; spectrograms can be saved as images with drag and drop support.

Spek is a lightweight windows application whose purpose is to help you build the spectrogram for an audio file in order to analyze the frequencies comprised in a sound. The layout is intuitive enough to be configured without having to consult a help manual or watch online tutorials, the program uses the GNOME platform, which includes the Lib, GTK+, Cario, Pango, as well as the FFmpeg Libraries.

Spek was desinged with an overall simplicity in mind, so it doesn't comprise many configuration settings; you are allowed to upload the audio files into the working environment using the built-in browse function or drag and drop operations. During our testing, we noticed that Spek carries out a task quickly and no errors showed up throughout the entire process; it is not quite friendly with system resources, so the overall performance of the computer may be hampered.

To sum things up, speak offers a simple yet efficient software solution when it comes to helping you generate spectrograms it can be easily installed and configured by all types of users regardless of their experience level

Features:

  • Support all popular lossy and lossless audio file formats thanks to the FFmpeg libraries
  • Ulta-fast signal processing uses multiple threads to future speed up the analysis
  • Shows the codec name and the audio signal parameters
  • Allow saving the spectrogram as an image file 
  • Drag and drop support, associated with common audio file formats
  • Translated into 19 Languages

I love using Spek for Windows because it's a really handy tool if you want to do a deep-dive into the acoustics of your audio files. If you're a music nerd like me, then you must check this program out. Its analysis is truly top-notch and it offers insights into your acoustics that are simply unparallel by competitor programs on the market.

Spek is a free and open-source software tool for acoustic spectrogram visualization and analysis. It can be used to analyze the frequencies of audio recordings, identify noise and artifacts, and visualize the audio signal in time and frequency domains. It supports a variety of audio formats, including MP3, WAV, AIFF, and FLAC.
