What do I want to do? With the shown code, we have created: text_01.wav,
test_02.wav, test_03.wav... Suppose the book Around the world in 80
days. Before the content of each track, I want to listen: "Around the
world in 80 days 1", "rround the world in 80 days ... When the device
plays the track, the name of it is shown in a display. But I am blind!
The name should be spoken not shown.
For each track of the book, I will create a temp wave with the name and
the number of the track and to join the temp wave with the respective
track. The two files will be created by my application, so I can assure
the sample rate and the other parameters are compatible. I don't need to
verify the possibility of concatenation. In my case, concatenation is
always possible.
