Audio Input buffer - Trying to access Audio Input on a sample by sample basis

[SamSpreadborough]

Hey everyone.
I'm new to Qt; trying it out from having previously used JUCE.

I'm trying to set up a simple audio input buffer of samples that I can access.
In JUCE you'd set up the audio device, and then access the input buffer via an audio callback:

void audioDeviceCallback (const float** inputChannelData, int numSamples)
{
const float *inL = inputChannelData[0];
const float *inR = inputChannelData[1];

while (numSamples --)
{

doSomething();

    inL++;
    inR++;
}

}

I've tried to get Qt set up in a similar fashion, but I've as yet been unsuccessful. The documentation refers only to recording to a file using QAudioInput from what I could see.

Can anyone offer any advice?

Hi and welcome to devnet,

QAudioInput returns a pointer to a QIODevice that will provide the audio data. Connect the readyRead signal from that QIODevice object to a slot of your class, there you can read the audio data received and make what you want with it.

Hope it helps
