uint FIRFilter::evaluate	(	soundtouch::SAMPLETYPE *	dest,
		const soundtouch::SAMPLETYPE *	src,
		uint	numSamples,

	)		const

Applies the filter to the given sequence of samples.

Note : The amount of outputted samples is by value of 'filter_length' smaller than the amount of input samples.

Returns

Number of samples copied to 'dest'.
