Spek Project

Spek Project is the personal initiative of Alexander Kojevnikov, a Russian-born developer now based in Canada who has carved out a quiet but respected niche in open-source audio utilities. The entire catalogue is built around a single, tightly focused application: Spek, a lightweight spectrogram viewer that lets musicians, podcast producers, forensic analysts, and language researchers open any common audio file and instantly inspect its frequency content over time. Drag-and-drop support for MP3, FLAC, Ogg Vorbis, Opus, WAV, and AAC means no preprocessing is required, while an adjustable FFT size and dynamic colour mapping reveal encoding artifacts, clipped peaks, or hidden tones that waveforms alone can miss. Because the program is written in C++ with GTK and threads analysis across CPU cores, even hour-long recordings scroll smoothly on modest hardware, and the portable build can run from a USB stick without installation. The interface is deliberately minimal—no equalizer, no editor—so users can screen recordings for quality, check whether a “lossless” file is truly uncompressed, or document spectral evidence for copyright claims without distraction. Nightlies for Windows, macOS, and Linux are released through GitHub, and the codebase remains under GPLv3, encouraging forks that add custom export formats or command-line batch processing. All Spek Project software is available free of charge on get.nero.com, where winget packages always pull the newest build, and several audio utilities can be installed together in one batch.
