SPEK
Acoustic spectrum analyser for audio files
GPL-3.0
ABOUT
File tags lie about bitrate and sample rate. A transcoded MP3 can look like a lossless FLAC. Spek draws a spectrogram so engineers see frequency cutoffs and fake hi-res without a full DAW.
INSTALL
brew install spekINTEGRATION GUIDE
1. Check whether a FLAC is a transcoded MP3 by reading the spectrogram
2. Inspect frequency cutoffs on a lossy encode before shipping audio
3. Compare two encodes of the same track visually
4. Spot upsampled 16-bit masters sold as 24-bit hi-res
