Auditory display is the use of sound to communicate information from a computer to the user. [1] The primary forum for exploring these techniques is the International Community for Auditory Display (ICAD), which was founded by Gregory Kramer in 1992 as a forum for research in the field.
Audio analysis refers to the extraction of information and meaning from audio signals for analysis, classification, storage, retrieval, synthesis, etc.The observation mediums and interpretation methods vary, as audio analysis can refer to the human ear and how people interpret the audible sound source, or it could refer to using technology such as an audio analyzer to evaluate other qualities ...
The lines are a grid, a method for dividing and containing recorded cartographical data. The land masses and oceans are cartographical data in a raw content (pictorial graphical) format. The text is in an alphanumerical symbolic raw content format. A recording format is a format for encoding data for storage on a storage medium.
Video of air pollution data from Beijing being conveyed as a piece of music. Sonification is the use of non-speech audio to convey information or perceptualize data. [1] Auditory perception has advantages in temporal, spatial, amplitude, and frequency resolution that open possibilities as an alternative or complement to visualization techniques.
During conversion, audio data can be embedded with a digital watermark to prevent piracy and unauthorized use. Watermarking is done using a direct-sequence spread-spectrum (DSSS) method. The audio information is then modulated by a pseudo-noise (PN) sequence, then shaped within the frequency domain and put back in the original signal.
Sonification - communication with sound, especially including machine-generated non-verbal sound; Auditory display - equivalent of a computer monitor, except with sound; Audification - subset of sonification which is the auditory equivalent of visual design, including data sonification within the broad field of design

Observable data is often known as raw data, or raw content. [4] A primary raw content format may be directly observable (e.g. image , sound , motion , smell , sensation ) or physical data which only requires hardware to display it, such as a phonographic needle and diaphragm or a projector lamp and magnifying glass .
