StereoSample Class

Detailed Description

The StereoSample class provides a simple wrapper for a stereo audio sample.

This templatized structure lets you treat a block of individual samples as an interleaved stereo stream. This is most useful when used with the templatized data() functions of QAudioBuffer. Generally the data is accessed as a pointer, so no copying should occur.

There are some predefined instantiations of this template for working with common stereo sample depths in a convenient way.

This structure has left and right members for accessing individual channel data.

For example:

 // Assuming 'buffer' is an unsigned 16 bit stereo buffer..
 QAudioBuffer::S16U *sample = buffer->data<QAudioBuffer::S16U>();
 for (int i=0; i < buffer->sampleCount() / 2; i++) {
     qSwap(sample[i].left, sample[i].right);
 }
