Spek - Acoustic Spectrum Analyser is a program used to analyze the acoustic spectrum, i.e. the distribution of the intensity of sound components depending on their frequency. The program presents the results of conducted analyses by means of a spectrogram.

The developer of the tool used FFmpeg libraries, so Spek supports a very wide range of music file formats. The program quickly handles sound analysis, showing information about the parameters of the audio signal and the codec used in the file. It also allows you to save the spectrogram as a graphic file, which allows you to conveniently share the results of your analyses.

Spec - Acoustic Spectrum Analyser was developed as part of an open source project and its source code can be found on GitHub.
