Oh I completely neglected that libsndfile automatically loads any
filetype it supports. You can open FLAC's as well as wave's and other
filetypes in the waveplayer example. But it loads the file all at once
and doesn't use any buffering, so you can't load really big files
because the memory allocat
I've fixed the performance issue with the wave player example. Instead
of constantly redrawing a large amount of data (it would max out my
single core), I've employed a caching technique.
Basically, the waveform only needs to be redrawn when the window size
changes. So I hold two buffers, one for

Before you ask, it was a new DLL. I never had it in my repo before,
not even in an earlier changeset, or in any of my other repos.
Btw, I've noticed something very interesting. I've pushed a 2.2
megabyte DLL in less than 2 seconds to the repo. That's impossible
with my limited ~20Kb upload speed. I wonder if github does some kind
of caching, if it does it probably did a hash check on my file, got a
match, and just copied an ex
I've just added a brand new GUI example!
This time it's a wave player that draws the waveforms of the left and
right channels of the wave file, and also draws the playback position
as a typical sequencer would do.
It also allows you to change the playback position, just point and click!
Here's a
The C examples compile and run fine, so I must be doing something
wrong on the D side.
Ok this does the trick: nm -D libportaudio.so
It does list all of those functions though.
IOW is there a utility I can use on Linux to list .so exports?

I've also tried manually copying the two (I don't know why there's
two) shared libraries to the local folder, the libportaudio.so and
libportaudio.so.2 files.
Command was:

Sure, I'll test it on Ubuntu sometime soon and see how it works there.

There's bindings for that too (although only Windows was tested):

PortAudio is really just a uniform layer over APIs which already exist
on the platform, so any synchronization problems those APIs have will
be reflected in PortAudio. I did some reading about this in the
portaudio newsgroups, and synchronization seems to be a difficult
issue to solve.
I'll resear
