URGENT : QMultimedia : get the datas of a RAW (audio) file.

[fitzy]

Hello !

The sound datas are stored into the RAW file as Signed Integers.

But the datas look like this :


þûþýþûþûþúþøà ¾Ã¸Ã¾Ã·Ã¾Ã¸Ã¾Ã¹Ã¾Ã¸Ã¾Ã¶Ã¾ õþóþòþñþðþðþà °Ã¾Ã¾Ã€Ã¾ÃÃ¾ÃÃ¾Â¿Ã¾Â»Ã� �ºþºþ»þ»þ¹þ¸þ� �·Ã¾Â´Ã¾Â²Ã¾Â±Ã¾Â¯Ã¾Â¯Ã¾Â� �þ*þ«þ©þ©þªþªþ ¨þ§þ¥þ¢þ¡þ*þŸ� �¾Å¾Ã¾Å“þšþ™þ™þ ™þ—þ”þ”þ†Ã¾â€œÃ¾ÂÃ¾Å’þŒþ‹ þŒþ‹þ‰þ†þÆ� �þ„

How can I get the values of the integers ?
I think that a QAudioInfo (cf. readData/writeData) might do it, but I don't know how to use it ! :(
(I already checked the documentation)

Please help !

I couldn't find any reference to QAudioInfo in the documentation.

There's a spectrum analyzer example that makes use of the raw data.
