Most real-world engines need to play multiple sounds simultaneously. Since QAudioSink only outputs a single stream, you must build a . qt audio engine
QAudioFormat format; format.setSampleRate(48000); format.setChannelCount(2); format.setSampleFormat(QAudioFormat::Int16); // ... check format support QAudioInput *input = new QAudioInput(device, format, this); QFile outputFile("recording.wav"); outputFile.open(QIODevice::WriteOnly); input->start(&outputFile); // Qt 6
When you need direct access to the audio buffer (for synthesizers, analyzers, or custom codecs), step down to the low-level API. // Qt 6.5+ QPermissions permissions
