Hello,

In May 2007, Jonathan Murpy-4 started a thread named “sndwarp”.  He
suggested creating a version of sndwarp with the following new features: 

1.  Reads directly from disk like diskin, without having to load the source
file into f tables.  This would prevent two problems: a) Having to split up
large sound files between multiple tables. b) Having to load the entirety of
large sound files into memory.  
2.  The inputs for window size, window density, and window randomization are
k-rate controls.

Does anyone know if these features were ever implemented?  There was
considerable discussion in the thread, but the thread just ended without
conclusion.

The reason I ask is that I’m building a GUI soundwarp “audio player”, where
you can control the time pointer, and other time stretch parameters on the
fly.  Having to split up large files between tables and not being able to
change the window parameters after a note has begun is causing me
significant development headaches.  I’m a Java developer, not a C
programmer, so I can’t really make these changes myself without causing even
more headaches.

Thanks,
Jonathan Eck

Could it be a choice to use pvsdiskin instead?

pvsdiskin doesn't offer the flexibility of sndwarp. You can do some
stretching etc with pvsbuffer and pvsbufread but there are still more
things the sndwarp can do that these do not. I recall the thread Jonathan
refers to and was disappointed that it just sort of ended without
resolution. It seems there have been some problems with sndwarp since ver.
5.0. I never had difficulties with older versions of csound. It would be
nice to have this useful opcode updated.
