示例1: pull

void Splicer::pull(AudioChunk &chunk)
{
	Uint32 left = chunk.length(), chans = chunk.format().channels;

	Sint32 *data[PG_MAX_CHANNELS];
	for (Uint32 i = 0; i < chans; ++i) data[i] = chunk.start(i);

	//Query exhausted each loop to refresh the value of "current".
	while (!exhausted())
	{
		//Pull data from next stream
		AudioChunk sub(chunk.scratch(), output, data, left, chunk.sync);
		current->pull(sub);

		//Partial advance
		if (current->exhausted())
		{
			Uint32 cut = sub.cutoff();
			for (Uint32 i = 0; i < chans; ++i) data[i] += cut;
			left -= cut;
			current = NULL;
			if (left) continue;
		}
		return;
	}

	//The Splicer is exhausted!
	chunk.cutoff(data[0] - chunk.start(0));

示例2: pull

			virtual void pull(AudioChunk &chunk)
			{
				if (!chunk.length())   return;
				if (!valid || finished) {chunk.silence(); return;}

				int samples, have = 0, need = chunk.length();

				//Cutoff marker if necessary
				if (have < need) chunk.cutoff(have);

				//Upsample data to 24-bit Sint32s
