Spek
Spek is an acoustic spectrum tool and audio frequency visualizer designed to decode audio streams and analyze their spectral density. It functions as an audio spectrogram analyzer that displays frequency distributions to help identify the sonic characteristics of audio files.
The tool specifically includes capabilities as a lossy compression detector, allowing for the identification of encoding artifacts and frequency cut-offs caused by lossy transcoding.
The software covers audio file inspection and spectral analysis, providing the ability to select individual audio streams and channels. Users can configure the analysis via adjustable window sizes and color palettes to tune the precision and appearance of the visualizations.
