I have just downloaded JUCE and try to run recording module in Demo examples ( JUCE-WINDOWS\examples\Demo\Source\Demos\AudioRecordingDemo ) , but it's fail. In isRecording() method, activeWrite's buffer object has error CXX0030-expression cannot be evaluated. After debugged, I found two problems. The first is sampleRate's value is zero. The second is after I added sampleRate's value is 44100, recording module can run but recording file has only 104 byte and of course it can't be play. What is the reason? Please help me.
