Description: The result of a constant-Q transform applied to the waveform of a C major chord played on a piano. The x axis corresponds to frequency mapped to the standard pitch names (increasing from lower pitches on the left to higher frequencies on the right). The y axis is time, with the start of the piano chord happening at the bottom and the release happening at the top (8 seconds later) The darker areas correspond to higher values of the Constant Q transform. The peak values are vibrating frequencies of the strings. The leftmost 3 strongest peaks are at the fundamental frequencies of the notes of the C major chord (C, E, G). The the remaining peaks to the right of the fundamental frequencies are overtones. This image was created using FFmpeg's showcqt filter, which is also available as a foobar2000 component as foo_showcqt, which is a port by Wamoc/Alireza Ayoubi.
