The page dedicated to listening is available in two versions:
1) The first version (based on Flash) is faster, more efficient and more attractive, but is not compatible with the old browsers. To reach it, please click here.
If you experience serious and persistent problems in viewing it, please try the second version (but try this first version, first).
2) The second version (based on Java) loads very slowly (you are warned…), is less efficient and less attractive, but is compatible with almost all the browsers. To reach it, please click here and wait.
