pysox-devel — Pysox development

[Mark H. <mar...@gm...>]

Hi!

I'm trying to build a pretty simple application using PySox, and it's
sort of getting a little difficult to follow the minimal documentation
there is available. Is there any way someone could write more
comprehensive documentation for the wrappers, *including* a list of
built-in effects? I had to hunt for days just to find the 'trim'
effect....

Also, I'm running into a bit of a problem with the library. I have a
conditional block that does the following:

1. Open a CNullFile
2. Create a CEffectsChain with the null file and an already-open file
3. Use a trim effect to chop out a small part of the null file
4. Flow the result into the other file
5. Re-open the other file
6. Create another CEffectsChain with ostream= the file we just flowed to
7. Create a ConcatenateFiles effect with the file we just flowed to and
another separate file, add it to the chain
8. Flow the result into the other file
9. Close and re-open the files to the point they were at previously, so
the conditional block doesn't make it impossible to do the rest of the
tasks.

When the conditional doesn't happen, the program runs fine (and even
does what it should do on the first try!) but the conditional not only
freezes my entire computer for about a minute, it causes an
out-of-bounds memory reference and the application crashes.

Is this a bug in the ConcatenateFiles code? Is it related to the fact
that I continue on to use MixFiles on two files, one of which is the
result of the above? Did I make a mistake?

Thanks for everything,
