Play a QAudioBuffer

Question

Which is the best way to play QAudioBuffer of a format supported by audio card? Have I to create a QIODevice and convert it to raw data manually or is there a better way?

Answer 1

A QAudioBuffer is very lightweight handle over a raw QByteArray. It is raw data already. You can think of it as a QByteArray with a few extra information fields attached to it.

You can write the QAudioBuffer::data() to a QIODevice returned by QAudioOutput::start().
