Many digital interfaces for audio engineering still resemble racks and cases of their hardware counterparts. For instance, DSP- algorithms are often adjusted via direct value input, sliders, or knobs. However, the frequency-domain visualized as spectrogram is used to analyse and manipulate audio signals. This is commonly limited to restoration, and not for creation or arrangement. Thereby manipulating audio via the frequency-domain in a visual way, sound-design and music production becomes more unrestricted and creative. This demo shows the current state of the possibilities and challenges for VisualAudio-Design.
