ANSARI Yusuf: Wasteland (animated spectrogram)

Yusuf Ansari: Wasteland
Wasteland is an electronic music composition, which has been realized by Yusuf Ansari during the period, he worked with Claude Lenners at the Luxembourg Conservatory for Music. The piece comes in 2 versions, using similar sound material: the first version has been mounted in the Logic Audio Software and the second one was programmed in MaxMSP.

The spectogram
This movie is an animated spectrogram of an electronic music composition. Realized with the Acousmographe-Software, the movie shows exactly what's actually happening while listening to the music.
This composition is a part of our new series of Spectrograms, which intend to provide a more complete approach for anyone, intending to listen to music in a deeper manner. While illustrating the sounds by pictures generated by themselves, we allow a better kind of investigation. The listener gets the opportunity to enter into a process, which gives him the opportunity to recognize - and sometimes expect - the sounds, he's able to see, because they are drawn by a software which uses a precise Fourier analysis.
These animated pictures use colors for representing intensities or dynamics (black = nothing, blue = low level, red = mid level and yellow = high level). The frequencies, going from 0 up to 22050 Hz, are represented in a linear scale from the floor up to the ceiling of the movie-window: equidistant rays represent sounds with harmonics and clouds illustrate noisy moments.
The spectrogram comes with a stereo waveform, which represents the normal way for illustrating sound files: the left channel is white and the red channel has got a red coloration. These waves are exactly superposed upon the spectrogram and represent the global dynamics of the pieces.
A red cursor illustrates at any moment the actual position and helps in reading this special kind of score.
Therefore, every movie of our series is a little tutorial for anyone, who intends to learn to read spectrograms and to enter into the investigation of sound events or recorded musical compositions.
This ability is also very important for any musician who wants to analyze the sounds he creates. In order to do so in real-time, we've developed our Soundalyzer-software, which uses the same colors for representing sound events.
