hello

	i processed an audiofile with flanger and resonx
	and then when reading this file i wondered why i get
	so many samples out of range when adding some instruments.

	after tolve's mail i looked what the waveform was like
	in this file and there was a huge dc-offset. when
	reading this file with soundin, i placed dcblocks
	and after that no samples out of range. 
	maybe out should have dc-blocking always?
