SonoUno is a sonification software for astronomical data presented on a table (txt or csv files). The software is being developed based on the study of other software (Sonification Sandbox, MathTrax and xSonify) and standards of accessibility like the ISO 9241-171:2008 (Guidance on software accessibility). In order to develop the first approach of a graphical user interface, we perform a theoretical framework based on bibliography of user cases, focused on blind and visual impairment people.

The develop language is Python and we use modular design, in order to do collaborative work. The sonoUno now is multiplatform, tested on windows 10, Ubuntu (16.04 and 18.04), CentOS 7 and Mac (Mojave and Catalina); the development team work continuously to maintain this benefit. The principal goal of the SonoUno is to allow the user to open data files (txt or csv extension), show the plot and sonify the data. At the moment, the sonification is perform by variation of pitch and the sonification settings allow to change the volume and the timbre.

Additionally, SonoUno allow to select a specific range of data on the ‘x’ axis, mark and save point of interest in the data, apply predefined mathematical functions (for example, logarithm and square) and manipulate the data arrays with an Octave interface. In the section settings, the user can configure the plot and some features of the sound.

Finally, the software allows the user to save the plot, a text file with the points marked on the data and a csv file with the plotted data.
