Spek (Acoustic Spectrum Analyser)

Spek helps to analyse your audio files by showing their spectrogram.

Audacity has a similar feature (among many others).

Another option is to just use sox (you probably have this installed anyway).

Code: Select all

sox yourfile.flac -n spectrogram -o spectrum.png

Thanks, I wasn't aware that sox does spectrograms!

Note to self - to prepare spectrograms for all the files (*.flac) in the directory do:

Code: Select all

for i in *.flac; do sox "$i" -n spectrogram -o "${i%%.flac}.png"; done
