''a posteriori'' sonification

The great majority of sonification examples available on the web are audio files that represent a sequence of several data layers of a certain phenomena (physical, astronomical but also metadata, web statistics, economics, health parameters) during a certain period of time. These are stored data converted to an audio file.

We call a posteriori when the data is sonified after being collected and stored. a posteriori comes from Latin and means "from the latter" or "from the one behind". It is usually used in philosophy to refer to a statement that comes after experience. While in real-time sonification we do not know what exactly will be the next data input, in a posteriori sonification, when we store a sequence of data we can take our time to analyze it and adjust our output sounds and test them. The data set is translated into a sound piece as a whole.

TwoTone

There are many a posteriori sonification applications that you can find online. TwoTone is a software program by Google that allows you to generate sounds from data. This software has its own database, and it is updated regularly. This shows how popular sonification is.
