Through the described digital processings, sounds are brought further into an electro acoustic repertoire. Initially concrete sounds sound more artificial and physically impossible. It was easier to reach such results with a rich starting points. Hearing the raw recordings, the ensemble did already doubt whether they were unprocessed. Results of highly varied processings with numerous controlling curves made it hard to predict the results. It is an exploration for the composer and sound editor.
With a sample rate of 96000 Hz, the sonograms show frequency contents up to 48000 Hz. A few of them show ultrasound frequencies which will not be perceptible for the human ear.
