Spek is a free, open-source acoustic spectrum analyser that renders spectrograms of audio files. It is a cross-platform desktop application built in C++ using FFmpeg for decoding and wxWidgets for the GUI.
Use cases
- view a spectrogram of an audio file
- analyze frequency content of a recording
- check audio quality or detect encoding artifacts visually
- inspect specific audio channels or streams
- compare DFT window sizes and functions when analyzing sound
When to choose
- you need a simple, free spectrogram viewer on Linux, Windows, or macOS
- you want to visually inspect frequency content of many audio formats via FFmpeg
- you prefer a lightweight native GUI over command-line tools like sox or ffmpeg filters
When to avoid
- you need programmatic spectrum analysis or numerical FFT output
- you need real-time live audio analysis rather than file-based inspection
- you need advanced editing or measurement features beyond spectrogram viewing
