void lpc_filter_fast | (EST_Track &lpc, EST_Wave & res, |
Synthesize a signal from a track of linear prediction coefficients.
Synthesize a signal from a track of linear prediction coefficients. This function takes a set of LP frames and a residual and produces a synthesized signal.This is functionally equivalent to lpc_filter_1 except it resduces the residual by 0.5 before filtering. Importantly it is about three times faster than lpc_filter_1 but in doing so uses direct C buffers rather than the neat C++ access function. This function should be regarded as temporary and will be deleted after we restructure the low level classes to give better access.
