Hi and welcome to devnet,

You can see how to do that in the details of QAudioRecorder's documentation as well as the linked example.

Thank you sir but ive been hovering the documentation for days and i really cant get something. Noob here sorry :( The documentation gives a dropdown list of my usb soundcard. What i am after sir is , i my self will manually assign my input device on my code without generating a drop down list. Thank you sir```
audioRecorder->setAudioInput(proper calling of my usb sound card)

QString str1 = ui->lineEdit_8->text();
QString filename = str1 ;
QString Nfile = "N";
QString Nfilename = filename + Nfile;
audioRecorder = new QAudioRecorder(this);
QAudioEncoderSettings audioSettings;
audioSettings.setCodec("wav");
audioSettings.setQuality(QMultimedia::HighQuality);
QString input1 = "Microphone (USB Pnp Sound Device)"; // part where i guess i have the wrong syntax to call my USB sound card
audioRecorder->setAudioInput(input1);
audioRecorder->setEncodingSettings(audioSettings);
audioRecorder->setOutputLocation(QUrl::fromLocalFile(filename));
audioRecorder->record();
QString input2 = "USB Audio Device"; part where i guess i have the wrong syntax to call my USB sound card
noiseRecorder = new QAudioRecorder(this);
noiseRecorder->setAudioInput(input2); 
noiseRecorder->setEncodingSettings(audioSettings);
noiseRecorder->setOutputLocation(QUrl::fromLocalFile(Nfilename));
noiseRecorder->record();

[edit: Fixed coding block SGaist]

If you want to hardcode that because you know what device you want to use. Use qDebug to print the values returned by audioRecorder->audioInputs(); on the console and then use that to feed input1 and input2.

@SGaist I seeem and i agree with you sir. But i cant get qDebug to work. I dont know how to print it. :(

SGaist

Doesn't qDebug() << audioRecorder->audioInputs(); work for you ?
