Hi guys, I just wanted to give an update on the integration of
librubberband into TerminatorX.
To understand rubberband, i wrote a small console Jack app that can play
wav files at diferent speeds, keeping pitch. It works well. The code is
attached.
I have a question to for the devs out there though: It seems to me that
i have to run process() a few times with a fixed blocksize before,
getRequiredSamples() returns something >0 in Realtime-mode. All other
options are default options. Is this true? I need some help on this
issue.
thanx Gerald

Hi, has someone looked at the code? I really need an answer to the
question.

Sorry, I didn't notice this earlier on LAD because the subject line
("Is TerminatorX development stalled?") bore no relationship to the
substance of the query. No slight to TerminatorX intended, but I
wouldn't normally look at messages on LAD about it!

You have to supply process() with a certain amount of data before
anything becomes available at output, yes. If you are using a small
fixed block size, then yes it is true that you will likely have to
call process() several times. You might like to consider querying
getLatency() first, after setting the initial ratios, and "priming"
the stretcher with that number of zeroed samples before you start.

Thanx, I'll look at the solution.
