Acoustic spectrum analyser. Spek alternative written in Rust. The program is used to create spectrograms of audio files. It uses FFmpeg for audio decoding, like the original.
This application is a GUI for ffmpeg's showspectrumpic function, which allows you to generate spectrograms from audio files. For a detailed explanation of the available options and their functionalities, the best place to check is the official ffmpeg documentation: https://ffmpeg.org/ffmpeg-filters.html#showspectrumpic
I built this because the original Spek appears unmaintained, and installing it on rolling release distributions like Arch Linux often caused dependency issues with older libraries.

The Windows installer is experimental and may not work perfectly on all systems.
MacOS builds are available, but I can't test them since I don't own any Apple devices. Use at your own risk.
