LAMA is the Audio Measurement Application that tells you what you do and not what to do! It is a toolbox of audio-measurement instruments that allow fast & easy setup, designed for live sound-reinforcement but also suitable for all other needs of audio-engineering.
The Spectrum Analyzer and Spectral History (Spectragram) instrument are used to monitor the audio-spectrum of every signal you are interested in, and of course they have various types of display -like iso-octaves or continuous- to customize the view to your personal likings.
