IHASpatialAnalyzer: is a new method to display the stereo behaviour of audio material over time. It is based on the data of a vector-scope or gonioeter, but displays the results differently. You should be familiar with the vector-scope in order to be sure, what can be seen with this tool. IHASpatialAnalyzer can be used for the analysis of impulse responses of reverberation units. IHASpectrogram: is a tool developed to analyze the frequency content of an audio signal. It shows you the strength of a frequency over the time. The strength itself is coded in colours.
