Spectral Representation

Spectrogram is a very powerful tool. Well it is possible to see the sound..differently. And not only possible but it tells us alot of stuff we simply do not know about.

What you see here is the song by Lady Gaga - Judas. What we actually see here is the vocals singing Judas.

This is a screenshot taken from a spectrum analyzer with 20 DB audio gain and 23 ms Resolution.

The Yellow is the hotter areas while blue and green indicate more colder areas. If we look closely at the display of the spectrogram we can see the colors are telling us everything. Horizontal axis representing time and vertical axis frequencies. The third dimension is the amplitude of a particular frequency at a particular time is represented by the intensity of color. The frequency axis can be either linear or logarithmic, depending on what you want to use the graph for.

Here we can not only see the area where the vocals have been cut but also see where they have been boosted making it very easy to find out how the professionals have equalized the vocals. And It doesn't matter really the colors are showing the hot areas in red. Most of the spectrum can be read and see exactly in what frequency are the cut or boost have been applied. So for example if you wonder where to boost or cut your vocals you can just load a song thru the advanced spectrum analyzer and it will reveal some pretty interesting stuff. Not only can vocals bee seen, completely everything from instruments, to kicks, claps patterns, snare rolls, layers and melodies can be. Not only that, the spectrum can also be manipulated by switching models in different ways but that is not the point of this article right now.
