Sonic Visualisation

This sonic visualisation involved a few stages. First, original music had to be created using an M-AUDIO Axiom air mini 32 midi-controller keyboard, recorded using the Ignite software package and exported as a .wav file. This .wav file was imported into a downloadable edition of Sonic Visualiser, a sonic analysis tool created by the Centre for Digital Music at the University of London. Sonic Visualiser created an exportable .png file of the .wav file converted into a spectogram. Information on the nature of spectograms can be found at charm.rhul.ac.uk.

Below is a copy of the .png file. To view it correctly, right-click the image, save it and then open it with Paint. This should allow one to view the entire image as a movable image in its proper scale.

The .png file is a static image without sound. Sonic Visualiser creates a .sv file that can be viewed if the software is downloaded but it is not exportable. To create a video of its playback necessitated using a camera, in this case an Olympus SZ-14.

The video below is a slightly cropped version of the visualisation (some bass frequency notes appear below the horizontal axis). It features green, rather than white, spectogram effects. As the camera could only record the sound distantly, there was a significant drop in both the quality of the audio as well as its volume (it may be best to playback at a high volume).

The video file below is a .wmv file version of a .mp4, converted using WinFF in order to reduce its file size sufficiently to enable its uploading.

Spectograms record the frequency, loudness and length of every sound. The louder the sound, the darker the colour. Notes sound when the image reaches the left vertical axis.
