Detailed Description

template<guint ORDER, bool USE_SSE>
class Bse::Resampler::Upsampler2< ORDER, USE_SSE >

Factor 2 upsampling of a data stream

Template arguments: ORDER number of resampling filter coefficients USE_SSE whether to use SSE (vectorized) instructions or not


Constructor & Destructor Documentation

template<guint ORDER, bool USE_SSE>
Bse::Resampler::Upsampler2< ORDER, USE_SSE >::Upsampler2 ( float *  init_taps) [inline]

Constructs an Upsampler2 object with a given set of filter coefficients.

init_taps: coefficients for the upsampling FIR halfband filter


Member Function Documentation

template<guint ORDER, bool USE_SSE>
guint Bse::Resampler::Upsampler2< ORDER, USE_SSE >::order ( ) const [inline]

Returns the FIR filter order.

template<guint ORDER, bool USE_SSE>
void Bse::Resampler::Upsampler2< ORDER, USE_SSE >::process_block ( const float *  input,
guint  n_input_samples,
float *  output 
) [inline]

The function process_block() takes a block of input samples and produces a block with twice the length, containing interpolated output samples.
