Detailed Description
This templatized structure lets you treat a block of individual samples as an interleaved stereo stream frame. 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 frame structure has left and right members for accessing individual channel data.
For example:
// Assuming 'buffer' is an unsigned 16 bit stereo buffer.. QAudioBuffer::S16U *frames = buffer->data<QAudioBuffer::S16U>(); for (int i=0; i < buffer->frameCount(); i++) { qSwap(frames[i].left, frames[i].right); }
See also QAudioBuffer::S8U, QAudioBuffer::S8S, QAudioBuffer::S16S, QAudioBuffer::S16U, and QAudioBuffer::S32F.
Member Function Documentation
StereoFrame::StereoFrame(T leftSample, T rightSample)
Constructs a new frame with the supplied leftSample and rightSample values.
StereoFrame::StereoFrame()
Constructs a new frame with the "silent" value for this sample format (0 for signed formats and floats, 0x8* for unsigned formats).
StereoFrame<T> &StereoFrame::operator=(const StereoFrame<T> &other)
Assigns other to this frame.
