AUDIO EXPERIMENTS 1

I feel that I must pay equal attention to the audio so as not to produce a conceptually misleading result.

I will use the window tones to program the sound as well as the forms of the animation. The window tones will form one part of the audio, the low frequency track (bass tones), and I will use dial tone frequencies to produce the higher frequency audio (melody).

Concentrating on the bass track first here are the audio results for the top three floors, read from left to right.


They were made by taking the brightness level for each window and converting them straight into a single frequency (67% brightness = 67hz).

The tone duration is dependant on whether it is a wide or narrow window section (long or short tone as with dial tones!). This means that each floor will follow the same beat rhythm of short and long sections and therefore result in a musical composition.

The audio tempo follows the tempo that I have rendered the visuals, if we say a narrow window is one section and a wide one two, each side contains 10 sections, each floor 20 overall . I will make one section half a second (15 frames), so 10 seconds per floor.

An addition at the beginning and end of each floor is an added tone (Dial tone 425hz0, signifying a working line is operating. I will use this to signify a change of floor level.

The changes are subtle for sure but when listened to together in one track will produce an interesting mutating bass line.
