Hi,
I have written a FFTW based block convolution jack client, but I am
having difficulty processing the last jackframes%L samples of the jack
buffer. I have read that it might be an idea to collect the samples
into a second buffer and process them independently of the jack
process callback, but I have no clue how to implement that. Any
suggestions would be appreciated.
I'm not sure that it will work for convolution, but this might help:

It hides the complexity of buffer management when doing fft+ifft, using a
callback which receives buffers of frequency domain data. The code also deals
with windowing the signal.
