YES c'es't one of the WAR book that is truly informative Eyrolles (and I bought some I have left across the throat to the report content / price)
The one is a good beginners of rflexion even if it is still a little hungry.
However, the accents are put on the real problem of the sound, which is a big step forward compared to other books cans.
We need more concrete examples, examples and sample .....
Otherwise a good buy ....
