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 :

þûþýþûþûþúþøþøþ÷þøþùþøþöþõþóþòþñþðþðþðþþÀþÁþÁþ¿þ»þºþºþ»þ»þ¹þ¸þ·þ´þ²þ±þ¯þ¯þ®þ*þ«þ©þ©þªþªþ¨þ§þ¥þ¢þ¡þ*þŸþžþœþšþ™þ™þ™þ—þ”þ”þ”þ“þþŒþŒþ‹þŒþ‹þ‰þ†þƒþ„

þûþýþûþûþúþøþøþ÷þøþùþøþöþõþóþòþñþðþðþðþþÀþÁþÁþ¿þ»þºþºþ»þ»þ¹þ¸þ·þ´þ²þ±þ¯þ¯þ®þ*þ«þ©þ©þªþªþ¨þ§þ¥þ¢þ¡þ*þŸþžþœþšþ™þ™þ™þ—þ”þ”þ”þ“þþŒþŒþ‹þŒþ‹þ‰þ†þƒþ„

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.
