The user interface of the final version of the system with two spectra loaded in, ready for analysis.

Chemical spectra are an important part of how research chemists analyse the outcomes of experiments. However these complex spectra can be very difficult and time consuming to analyse. This paper outlines an investigation into using sonification to improve the understanding and ease of analysis of chemical spectral data. The project specifically uses sonification techniques to display Nuclear Magnetic Resonance (NMR) spectra.

Two sonification methods were designed to offer different perspectives on the data; "Spectral Audification" allows a quick overview of the data while maintaining its subtleties whereas a simple parameter mapping method allows more in-depth analysis of the spectra such as the use of rhythmic patterns to make sets of peaks easily identifiable.
