  In the last decade, the multi-sensory approach to data analysis has gained
relevance. The possibility of including people with vision difficulties in the
field of education and the dissemination of science is part of it. However, in
the field of scientific research, the topic is not yet accepted, mainly due to
the lack of conclusive evidence related to its robustness and performance,
except for a few exceptions. On the other hand, very few of the tools that
allow data to be sonifyed are focused on the user or have an interface that
allows controlling the sound production process and, at the same time the
visualization of data. Of those that meet this requirement and present
application in the field of astronomy and astrophysics, only four have included
people with visual disabilities in the design and only two of them have carried
out tests with users in Focus Groups during its development. This work details
the characteristics of sonoUno, with its end-user-focused design, its
capabilities in specific use cases in astrophysical data analysis related to
spectroscopy and photometry, following the basic software functionalities while
also introducing some innovation.
