Xenakios:
Thanks for the update! The sound format issue seems to be fixed.

However, I am wondering why the new build seems a bit slower than the old pvoc with the sound format bug? Can the speed difference be just because the old build wrote just 16 bit files whereas I am making the new build write 32 bit floating point files? Could it be that you accidentally posted a debug binary or some such for Windows now? :)

Actually, even the older pvoc program seems to run curiously slow compared to the CDP programs that actually process the analysed data...Might there be some chances for optimizations?

rwdobson:
Is this the  PC or the Mac version showing the slowdown?

I tested only on Windows. The slowdown isn't very big.

Xenakios:
It occurred to me that maybe the reason for the pvoc program being somewhat slow is because of its extreme amount of text output it produces...I realized this now that I tried running pvoc anal with a "long" input file (about 6 minutes) via the JUCE C++ library's ChildProcess. I already had to change that code in JUCE's Windows implementation to have more buffering for the process's text output. But now I ran into a situation where I had to increase the buffer amount even more.

Perhaps it could be a good idea to produce less progress text output while pvoc runs...?
