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
What do you mean by "the last jackframes%L samples" ??
The process() callback tells you to process nFrames samples.
Are you wanting to access the samples the preceeded this?
If so, you'll need to store them somewhere yourself. Jack
doesn't store them.
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.
You don't necc. need to process them independently of the
jack callback. However, you will need to create your own
buffer to store your data.
However, if your calculations can't be done within a single
process() callback without taking too long, then you will
either need to break up your calculation so that it will fit
(time-wise) into the process() callback. If you can't do
that, then you /will/ need to process them independently of
the jack callback.
