BLOCKFRAMEPAIRACCEL - Precompute structures for block processing

Usage

F = blockframepairaccel(Fa,Fs,Lb);

Description

[Fao,Fso]=blockframepairaccel(Fa,Fs,Lb) works similar to blockframeaccel with a pair of frames. The only difference from calling blockframeaccel separatelly for each frame is correct default choice of the slicing windows. Frame objects Fa,Fs will be accelerated for length 2*Lb.

The following optional arguments are recognized:

'anasliwin',anasliwin : Analysis slicing window. sliwin have to
be a window of length 2Lb or a string accepted by the firwin function. It is used only in the slicing window approach. The default is 'hann'.
'synsliwin',synsliwin : Synthesis slicing window. The same as the
previous one holds. The default is 'rect'.
'zpad',zpad : Number of zero samples the block will be padded
after it is windowed by a slicing window. Note the frames will be accelerated for length 2*Lb+2*kv.zpad.
