示例1: checkNumberOfChannelsForInput
// Any time a connection or disconnection happens on any of our inputs, we potentially need to change the
// number of channels of our output.
void ChannelMergerNode::checkNumberOfChannelsForInput(AudioNodeInput* input)
{
ASSERT(context()->isAudioThread() && context()->isGraphOwner());
// Count how many channels we have all together from all of the inputs.
unsigned numberOfOutputChannels = 0;
for (unsigned i = 0; i < numberOfInputs(); ++i) {
AudioNodeInput* input = this->input(i);
if (input->isConnected())
numberOfOutputChannels += input->numberOfChannels();
}
// If the actual number of channels exceeds the max allowed, just drop the excess.
numberOfOutputChannels = std::min(numberOfOutputChannels, AudioContext::maxNumberOfChannels());
// Set the correct number of channels on the output
AudioNodeOutput* output = this->output(0);
ASSERT(output);
output->setNumberOfChannels(numberOfOutputChannels);
// There can in rare cases be a slight delay before the output bus is updated to the new number of
// channels because of tryLocks() in the context's updating system. So record the new number of
// output channels here.
m_desiredNumberOfOutputChannels = numberOfOutputChannels;
AudioNode::checkNumberOfChannelsForInput(input);
