Blue Cat's FreqAnalyst is a spectrum analyzer that lets you monitor the spectral content of your audio signal in real time. It has been designed to provide extreme smoothness and high resolution for both time and frequency: unlike most spectrum analyzers, Blue Cat's FreqAnalyst is able to display continuous variations even with a very high frequency resolution, thanks to its unique smooth interpolation algorithms.
Most aspects of the audio to frequency display conversion can be managed, which lets you total control over the monitoring. A special thresholding system has been developed to help you see the important parts of the spectrum easily. In case you need extra precision in a particular frequency range, you can zoom the display and check the part of the graph you are interested in.

SG-1 gathers some features which are usually isolated in other sonogram tools.
It works in real-time. It continues analyzing in the background, and only stops when you freeze it. Both in frozen or running mode, every time you click or drag within the sonogram area, frequency and amplitude rulers highlight the values corresponding to that point.
A little LED-like screen shows you in detail analysis information and parameter modifications, or the transport position when idle.
The unusual thing: it comes with six scientific color palettes (twelve considering they can be inverted, by clicking the palette twice), which can be switched on the fly with a single click. Each of them can highlight different dynamic ranges, from high power kickdrum beats, to little spikes coming out from the noise floor.
Every palette can be shifted by simply dragging the dB ruler, to better contrast the right amplitude ranges.
You can vary the number of snapshots-per-second on the fly, to increase or decrease the time resolution. At any time you can change the zoom ratio, without loosing in resolution over the signals which have already passed by.
Of course you can scroll the zoomed screen while analyzing, to easily locate the frequency range of interest.
A mark button is provided: it allows highlighting interesting parts of the waveform for subsequent individuation.
