FYI : i am currently supervising a students project about this, for the
whole academic year.
I submitted this project planning to enhance and extend Scilab sound
capabilities, and it
was actually assigned to a group of 5 students in School of engineering.
Implementing a sound recorder through the standard microphone is one of
the addressed topics.
It is set as a priority for the mid-term evaluation of the project, in
The priority is also to get a fully portable solution, and without C/C++
code and compilation
using any Scilab API, that would require to be reviewed and recompiled
for each new Scilab 6.x release.
We know how this makes external modules quickly obsolete and unusable.
On this aspect, porting the portaudio and sndfile modules to Scilab 6
has been considered.
But after being assessed, it looks too hard to do. BTW, it would not
remedy to the need to
recompile. So, it is not a priority of the project.
Using Java in open source projects requires more care today than one
year ago, due to
major changes in Oracle Licenses policy since early 2019. But java is
still a first way to be
