Process Microphone voice using Qt

Arun Kumar K S asked:

Hi,

I am developing one sound processing application using Qt as front end
For that how we get data samples from a microphone and need to process it using Open Source SoundToch library,

The method I need to implement as given below

m_soundTouch.putSamples((SAMPLETYPE*)block->lpData, block->dwBufferLength / sizeof(SAMPLETYPE));

I tried by overriding qint64 writeData(const char *data, qint64 len); in QIODevice but i failed to implement above method and change its pitch and produce new voice as output in speaker

Thanks,
Arun Kumar K S
