Audio recorder examples with Qt 4.5

Hi,

I am developing a program for embedded device (Blackfin BF548). The program needs an audio recorder build in it. Currently, I am able to record sounds into an audio file. But the problem is, I cannot stop recording when I need it to. I tried QThread using the method here. But the thread will only quit after while loop ends, which is never. And terminate() is a bad idea.

Any solutions?Or does anyone has similar example codes?

Please note: The embedded version of Qt I have is Qt 4.5. Thanks.

Kind regards,
Wen
